Painting the exterior surfaces of your home takes very different planning and preparation from doing interior spaces. This is a comprehensive guide to the entire process so that your home interior design is ready for the cool weather
’Tis the season to be outdoors, and if you are looking forward to have that leisurely cup of tea in the balcony or throwing a barbecue for your friends in the courtyard, it is time to get your house ready. The outside of our homes are exposed to a lot in terms of weather, elements, pollution, ageing and damage that the paint job on interior surfaces don’t have to deal with. Due to these added factors, you need to keep a few points in mind while choosing the right emulsion.
Plus, if you are looking for a personalised, stylised look for the exterior walls there is so much on offer that you won’t know what to try! For all those questions you might have about the type of products, application and surface prep, we’ve got the experts to clue us in:
Identifying And Tackling Problem Areas
Before you get started with all the steps involved in painting including surface prep, you need to check your exteriors for various kinds of damage and fix those first. There are several issues you should be on the lookout for:
1. Dampness in the walls can be caused by exterior or interior leakages and it is crucial to understand what is causing it. Damp spots can result in algae growth, formation of bubbles in the paint, flaking and peeling of the paint, and a continued weakening of the structure over time. Civil repair work might be required along with interior and exterior waterproofing treatments. Read our comprehensive guide to waterproofing here. To deal with algae growth, properly scrub and clean the surface with a solution of bleach and water. After it is completely dry, you can prep the surface with Trucare Bioblock from Asian Paints which is designed to kill and prevent the growth of algae and fungi on surfaces.
2. Age and exposure to the elements causes cracks, especially on the exterior walls. This can also lead to weed growth near and within the cracks. Remove the weeds and seal in cracks before starting the painting process. To seal the cracks, Asian Paints recommends using their SmartCare Crack Seal which is a fibreglass reinforced, ready-to-use crack-filling compound for masonry surfaces or their SmartCare Textured Crack Filler which is an acrylic crack filler with a grainy texture for exterior surfaces.
Preparing Your Surfaces For The Paint
After you have taken care of the problem areas, you will need to prepare the walls correctly for the paint to adhere to it well. This could include re-plastering or application of putty and primers. Asian Paints provides a range of undercoats for exterior surfaces depending on your needs.
1. Clean the surfaces thoroughly to remove dirt, dust and other residue. You can scrape the walls with a wire brush where necessary and finish with jet washing the surfaces. You will also need to sand down the surfaces to remove loose particles and old paint flakes.
2. It is at this stage that the professionals might recommend re-plastering in case of major damage. Freshly plastered surfaces are alkaline which can cause issues like patchiness and lime blooming which is a white discolouration on the paint. To avoid this, you should let the plaster cure properly with water for at least four weeks before painting.
3. You might then need to apply putty over any minor irregularities or imperfections in the surface for a smooth canvas.
4. After the putty dries completely, it’s time to apply a primer. This step is important as the primer enables the paint to adhere to the wall better and provides a layer of protection to make the paint job last longer.
5. Pay attention to your roof tiles at this stage. This surface directly faces the sun and rain while also being porous so the tiles might need a special coating. Check out Asian Paints’ Apex Tile Guard that comes in a range of shades. This water-based coating for roof tiles, Kerala bricks and non-porous baked clay tiles provides water repellence and resistance against algal and fungal growth.
Choosing The Right Exterior Paint
There are a few key points to keep in mind when deciding what exterior paints to use depending on different locations and factors.
1. Emulsions are water-based acrylic paints. These have
‘high-density particles’ that result in a silky and smooth finish.
2. Weather conditions like harsh sunlight and humidity affect the durability of your paint. Look for emulsions that are UV-resistant to avoid fading.
3. Pollution can also affect how long your walls will look fresh. Erosion- and dust- resistant versions help protect against this.
4. Water leakages and dampness can be tackled with
5. If your exteriors are prone to algal growth, choose emulsions that come with anti-algal protection.
6. Emulsions also come with crack bridging up to 2 mm which is a good option for walls with minor surface cracks.
7. Choose emulsions that come with at least a five-year performance warranty that covers against issues like fading, flaking, peeling, algal and fungal growth.
8. Lastly, you can purchase sample sizes to try out different colour combinations. Asian Paints also has a wonderful guide, which you can download here, to help you choose the right colours and combinations for the exterior spaces.
