how do I apply for a job at asian paints?

  • Please upload your CV at the careers page on this website. The HR department will get in touch with you if there is a relevant opening.

can the products be applied during rainy season?

  • Well, every product has its own drying time. And its quite risky to paint during the rainy season. If in case, you go ahead with the painting and it rains heavily, not allowing enough time for the paint to dry , you might have to face problems. Hence, we recommend you to observe the weather condition and then go ahead with painting.

how long should one wait before painting in case of a new construction?

  • You need to allow a curing period of 45 days for exteriors, and 3-6 months for interiors.

what does curing period mean? why should one follow this process?

  • Curing period means the walls should be left bare. This is because the paint should not react with the chemical present in the cement.

can ink or other stains be washed off?

  • Most wall paints made by Asian Paints are washable, compared to other brands. Common stains, like pencil marks, can be easily cleaned. But, it is difficult to clean tough stains. You may try using a mild detergent to clean the stains.

how do the stains on the floor be removed after the painting is over?

  • Any paint stains should be wiped off immediately. Use a mop and clean up each room after the painting is over. Enamel paint stains require thinner for cleaning. You can also use turpentine to scrub them off the floor.

do any asian paints paint offer protection against termites?

  • Yes. If entire furniture is coated with Wood Finish, it is difficult for the termites to attack the surface.

what paints can be used on the surface where there is already attack of termites?

  • If the termites have already infected the furniture, you will have to treat the furniture for termites, with the solutions easily available in the market, e.g. Termiguard. No Wood Finish is Termite proof.

what is acrylic?

  • Acrylic basically means water based products, which have High Density Particles that result in an excellent finish on your walls.

what are emulsions?

  • Emulsions are acrylic based paints, which are water based. These are available for Interior Wall surfaces as well as Exterior Wall surfaces.

what is the difference between solvent-based and water-based paints?

  • Water-based paints are diluted with water, while solvent-based paints are diluted with solvents like Mineral Turpentine Oil (MTO). Emulsions are water-based paints while enamels, lustre and matt finishes are solvent-based paints. Emulsions look better on walls and are ideal for drawing rooms. Solvent-based paints are ideally suited for kitchens and bathrooms since they are water-resistant. Enamels are used on wood and metals.

what are primers and putty?

  • Primers and putties are applied on the paintable surface before the final paint is applied. Before you apply putty or primer you have to sand the wall with sandpaper. Putty is a kind of paste prepared for applying on walls to fill in any minor dents or to level the surface. Since putty is absorbent, a coat of paint applied directly over it would lead to the paint being absorbed unevenly, leading to patches. A primer layer on top of the putty is a must. It takes away the unevenness caused by putty and the final paint comes out perfect. Thus, you get both protection and good finish.

what is the role of primer paint?

  • Primer paint is a preliminary layer of coating that is applied on the materials prior to the paint. It ensures that the paint adhesion to the surface is proper, enhances the durability of paint, and imparts extra safety to the surface being painted. Primer also seals pores in permeable materials, and averts bleeding from knots. If suitably applied, primers will enhance the life of the paint, and also improve its appearance.

what is the pre-painting procedure for interiors?

  • The pre-painting procedure for Interiors includes the following steps: 1) Check surface for dampness or water seepage. 2) Rectify the water seepage problem at the source. This could mean repairing leaking plumbing or cracks in the exterior walls. 3) Any loose plaster should be removed from the wall. Check for loose plaster by tapping on the walls. Any hollow sound means the plaster is loose. 4) Masonry work to be undertaken to fill up all cracks and repair broken plaster.

what should be taken care of while painting?

  • While painting, you need to keep in mind some tips: 1) To save on costs, buy paint in the largest pack possible. 2) Stir and strain the paint thoroughly before application. 3) Rectify existing surface problems like cracks/seepage, etc before the actual painting process. 4) Ensure that the paint is bought from an authorized dealer. 5) Ensure that the shop has an additional quantity of paint in case you need it later (of course, at our dealers especially Colour World, you will not find this problem.) 6) If you are using thinners, primers and undercoats, ensure that they are of good quality. 7) Always clean spilt/splashed paint with a recommended thinner while it is still wet.

what precautions should be taken while painting?

  • While painting, one must take a few precautions, such as: 1) Do not use cotton rags for cleaning, use soft synthetic or muslin cloth.  Otherwise, threads will stick to the surface leading to a patchy, uneven finish. 2) Do not apply the next coat without the first one drying, otherwise you will have a wrinkly, patchy finish as well as loss of gloss. 3) Do not sandpaper very hard, otherwise there will be scratches, roughness and poor gloss. 4) Do not apply very thick coats, otherwise there will be a thick rough finish, resulting in slow drying. 5) Avoid mixing paints yourself. Buy readymade paints as far as possible, otherwise there will be patchy and inconsistent columns in the finish.

can one use kerosene for thinning of paint?

  • We do not recommend you use kerosene for thinning of paint, otherwise there will be delayed drying and reduction in gloss.

what happens if thick layer of putty is applied?

  • If a thick layer of putty is applied there is a possibility of cracks developing after a period of time.

how quickly does the paint dry?

  • Duration of painting depends on the number of rooms you plan to paint and how many painters are working. Paint drying time for Emulsion is 4 hours minimum, though 6 to 8 hours is preferred. Distemper takes 6 to 8 hours, while Enamel, Primer, Lustre and Matt Finish requires 8 to 10 hours. Wood Finishes takes 2 to 3 hours.

should a newly painted house be vacated for some time?

  • Your house will smell a little but it is not necessary to vacate it. Keep the windows open and the smell will disappear faster.

how many coats of paint should be applied?

  • Depending on the condition of the walls and the colour of previous paint, 2 to 3 coats should be applied.

how does one check whether curing is done properly or not?

  • Use PH paper (Range 8-14). PH of the plastered wall should be less than 12.

what are the main reasons for failure of paint after application on surface?

  • The main reasons of paint failure after application on surface are the applicator and improper treatment of surface.

what is the relationship between dry film thickness (dft) and wet film thickness (wft)?

  • The relationship between dry and wet film thickness depends on the volume of solids in the coating. Solids by volume is normally given as a percentage of the total volume of tha paint. DFT = WFT X solids by volume e.g. If Wet Film Thickness is 100 microns and solids by volume is 75% (0.75), Dry Film Thickness comes to be 75 microns.

on what factors does wet film thickness depend?

  • The applied wet film thickness depends on many variables such as the type of coating, application method (air pray, brush, roller, airless spray, electrostatic, tribo gun, etc.), equipment quality, operator, substrate material, the size and shape of the part, etc. Incorrect coating thickness could lead to technical problems or excessive costs.

what problems can a very low dry film thickness lead to?

  • Extremely low dry film thickness can lead to: 1) Insufficient corrosion protection 2) Hiding power problems 3) Erosion - removal of paint film from selected areas 4) Grinning - underlying surface is visible 5) Rust spotting 6) Undercutting - visual corrosion beneath the film

what problems can very high dry film thickness lead to?

  • Extremely high film thickness causes problems like: 1) Extra material costs 2) Sagging (sags), runs - downward movement of paint soon after application 3) Alligatoring - very large cracking 4) Cracking 5) Mud cracking - paint appears as dried-out mud flat with network of random cracks 6) Tackiness - stickiness in film

what is the role of primer in paint?

  • Primer paint is the preliminary layer of coating that is applied on the materials prior to painting. It ensures that the paint adhesion to the surface is proper, enhances the durability of paint, and imparts extra safety to the surface being painted. Primer also seals pores in permeable materials, and averts bleeding from knots. If suitably applied, primers will enhance the life of the paint, and also improve the appearance.

why are darker shades are more expensive?

  • Dark shades are more expensive due to the pigment's (mostly organicin) which are added to colour the base and get the required shade. Darker shades mean more quantity of pigments.

what are the different types of cracks and how can they be treated?

  • Cracks occur as buildings age. Temperature changes and weather conditions make them grow. They can be classified as structural or non-structural. Structural Cracks: Structural cracks are usually found in the load-bearing parts of the construction, like beams and columns are serious. They are caused by movements of the foundation, shrinking of masonry as it dries or heat-related roof shifting. They form in straight vertical or horizontal lines and or stepped diagonal lines. These cracks should be taken care of by specialists. Non-structural cracks: Non-structural cracks refer to cracks in the plaster of interior or exterior walls. They are mostly caused by reactions within plaster compounds and building materials, and external forces like temperature changes, environmental factors etc. They can also be caused by use of poor materials and inferior labour. They are usually haphazard and not very wide and are found on the flat portions of the wall and not on the load bearing areas. They can be effectively treated using crack filling compounds. Make sure to fill till the wall is level.

after filling cracks, the treated part of the wall is not level with the rest of the wall. Is this shrinkage?

  • Most water-based crack fillers contain some amount of water along with other ingredients, so that it can be applied easily with a putty knife. Once the crack is filled in with the paste, the water may evaporate from it, causing it to depress a little. This is called shrinkage. The issue can be solved easily by applying multiple coats till the crack is fully filled and all shrinkage accounted for.

why is low voc important?

  • VOCs or Volatile Organic Compounds are substances within paint that give off harmful emissions. These emissions continue long after the paint has dried.They have a strong odour, and cause a variety of health problems such as headaches, dizziness, asthma and allergies. They are also linked to cancer. Select a Low VOC finish so that your family and your children are not exposed to harm.

why is surface preparation important?

  • For paint to adhere well, to perform over time and display all its characteristics, the substrate must first be prepared properly. Surface dirt will prevent the paint film from adhering to the substrate and will peel off faster. If fungus is not removed, new growths could appear even on the newly painted film. Flaking paint will also reduce the new paints ability to adhere. The smoother the surface, the better the finish and performance. Fill all holes and sand surfaces to create an even surface for the paint.

can I wipe painted walls with water to clean them?

  • New generation paints have excellent washability characteristics. This means you can wipe them with mild detergent and water to remove stains, without affecting the colour or the finish of the paint. Most beverage, food and dirt stains, and some chemical patches can be removed in this manner. Washability characteristics differ from paint to paint so check the technical features to understand what performance you can expect.

how can we avoid the smell of paint?

  • Water-based finishes are usually odour free. Do keep windows and doors open while painting. However, a slight smell may linger for a few days if you’re using a solvent based paint.

how do I remove fungal or algal growth on walls?

  • Brush the affected area thoroughly with a wire brush. After the growth is removed, clean the surface with a bleaching powder solution made by mixing 50g bleaching powder in 1 litre of water. Apply on the affected area with a sponge, and leave the solution on overnight. After it dries, wipe it off with clean water. This will effectively remove the growth. However, if there’s dampness in the area, the growth may recur. Therefore it is a good idea to waterproof that entire area. Keep doors and windows open so that the area is exposed to air and sunlight.

how do we remove paint from an electric board?

  • First, ensure that all switches are off before you start removing the paint. If the paint splatters are recent, they can be cleaned with a cloth soaked in warm water. If they have already dried, scrape off with a paper cutter, after first wrapping its blade in a cloth to prevent scratches from forming. Do not use any strong solvent as it may damage the plastic surface of the panel. Do not switch on any fixtures till the board is dry. You can also use mineral turpentine oil to remove paint from glass and steel. Do note that the recommended method for painting involves proper masking of light fixtures and other elements in the house to avoid such problems.

what are the best conditions in which to paint?

  • Try to paint when temperatures are above 3 degree centigrade and relative humidity is less than 85%. For more details refer to the technical data sheet of your selected product.

what is the difference between waterproofing and damp proofing?

  • Damp proofing is a system of control which prevents moisture from passing through walls and floors into interior spaces. It increases moisture resistance, but does not completely prevent water from entering the surface. Waterproofing is a more complete method of resisting moisture as it stops water seepage caused by hydrostatic pressure, which is the rising of ground water into your surfaces. Damp proofing uses materials like tar, waterproofing is more environmentally friendly and uses materials like rubber.

what is the difference between leakage and seepage?

  • Seepage and leakage are very similar and are often confused. Seepage is when water escapes from all over a porous surface, usually leading to damp patches. Leakage is when water or any liquid escapes through defined cracks or holes on a surface. It usually appears in the form of drips. Depending on whether the problem is leakage or seepage, the wall can be treated accordingly.

how do you measure moisture content in the substrate?

  • The most effective way to measure moisture within a substrate is to use a moisture meter. This is usually carried out by professionals. Moisture meters have LED displays which show the moisture content, usually in % MC. ASTM, the American regulating body, details 5 test methods. The plastic sheet method involves taping a clear plastic sheet to the surface and examining it for moisture after at least 16 hours. Other methods include using specialised in situ probes and infrared thermography.

how do I ensure moisture in the wall does not blister the paint?

  • Moisture causes blisters, where the paint lifts from the surface in little bubbles. It usually occurs when moisture seeps through exterior walls into the home, or through damp interior spaces like bathrooms, to the exterior surface. It can also happen if paint is applied on a damp surface. Check for sources of interior and exterior moisture, and deal with them by installing vents, exhaust fans or sidings as appropriate. Then, scrape away all loose paint and sand the surface. Repair old caulk. Once the surface is completely free of old coatings and fully dry, you may repaint with a high quality water-based paint.

what is the difference between a sealant and an adhesive?

  • Adhesives and sealants perform two different functions, though some of the properties are common. Adhesives are used to bind two materials together and prevent them from separating. Sealants are used to block gases and liquids from entering the surface on which it has been applied. Depending on the type of sealant, they have multiple functions; they keep out moisture, provide insulation, and protect against fire. Some sealants may have adhesive properties, and some adhesives may have sealing qualities. However, sealants are generally more elastic to stretch over a surface and have less strength than adhesives which must hold together two surfaces.

what is Movement Accommodation Factor (MAF)?

  • Movement Accommodation Factor (MAF) refers to the ability of a sealant to expand or contract to accommodate movements in the joint. It is expressed as a percentage of the joint’s minimum size. MAF is important because all materials change in size depending on the temperature.

how can we dispose paint?

  • Avoid wasting paint. Empty containers may also contain some residue of the paint, so they must be disposed of safely. Dispose of surplus and non-recyclable products via a licensed waste disposal contractor. Disposal of this product, solutions and any by-products should at all times comply with the requirements of environmental protection and waste disposal legislation and any regional local authority requirements. Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains and sewers.

what safety precautions must be followed while painting?

  • Store your paints in cool dry conditions. Ensure there is adequate ventilation during application. Wear overalls, goggles, dust masks and gloves and avoid all contact with skin and eyes.

my wall has overlap marks. how can I avoid this?

  • Overlap marks usually happen when you paint in large sections and it begins to dry before you paint the area next to it. Make sure you paint in smaller sections.

how do we prevent brush marks on the wall?

  • Brush marks are usually caused by improper paint dilution, worn out brush bristles or poor application techniques. Experienced painters do not face this issue. Check if the issue is caused by one of the reasons mentioned, and get in touch with us if it persists.

why is it important to carry out paint thinning correctly?

  • Thin paint as recommended by the manufacturer. Both overly thinned or insufficiently thinned paint will not perform as indicated. Some products can be used without thinning, others require varying degrees of thinning. Make sure you use the recommended thinner and ratio at all times.

why is it important to use the right tools?

  • The recommended tools vary from product to product. Depending on the surface, consistency of finish or type of look required, you will have to use brush, roller or spray as recommended. For more porous substrates roller or brush is ideal. Fully solid floor screeds are laid on with trowels. Whereas for decorative indoor finishes, there are specific tools instrumental to creating the look. Do pick the right tool to ensure the right finish.

how do I decide how much paint to buy?

  • Use our paint calculator feature to figure out the amount of paint needed for your project. Usually, one litre yields one coat of a little less than 100 sq.ft of surface area, but this varies significantly depending on the surface finish and type of paint. Rough and textured surfaces will yield less coverage.

how do I choose the right colours for my home?

  • The colours you choose will depend on your personal tastes and preferences. Colours are intricately linked with mood, and can elevate or depress your spirits. For rooms that require rest and repose, opt for cooler colours from the blue, green and lavender families. Pastels will work very well in such spaces, while dark colours may be overwhelming and depressing. For rooms that are about energy and vitality, such as living rooms, family rooms or home offices, try warm colours from the red, orange and yellow families. Mild warm shades such as peach and lemon yellow create happy atmospheres. Of course, vibrant colours must be used carefully; try to restrict them to feature walls or décor accents such as furnishings or art. For smaller, darker spaces, use light colours to liven them up and create an illusion of space. Using neutral colours also helps you play off your prized objects.

what is the difference between colour and tone?

  • Colour is a phenomenon of light caused by how our eyes detect differing qualities of projected or reflected light. Hue defines pure colour. Tone is a visual property of colour. Tone is softer than the original colour as colour is mixed with white, greys, black.

why do colours on my computer screen look different when I print them?

  • Monitors and printers may be calibrated differently leading to differences in colour. When in doubt, refer to a physical shade card from Berger Paints available at one of our outlets, or request a wall swatch.
