A guide to exterior acrylic paint: which brand is best for Thai sun, and won't peel however much it rains

Thailand's fierce sun combined with year-round humidity and rain is what makes exterior walls peel, chalk, grow mould and fade quickly. Choosing a highly durable exterior acrylic emulsion paint is therefore the best long-term investment to keep your house looking new and protect the concrete structure from moisture effectively.

Checklist of features your exterior paint must have

When buying exterior paint, don't just look at the colour — read the specifications on the side of the can. Extra-durable paint (10-15+ year grade) should have these specs:

• 100% pure acrylic: strong adhesion and a dense molecular structure, so the paint doesn't peel easily and stands up to the weather
• Heat reflection (UV protection / cooling technology): lowers the heat built up in the wall, keeping the house cooler and saving on electricity
• Stain-resistant and washable (self-cleaning / dirt shield): rain washes the dust off by itself, so the wall stays clean and bright
• Mould and algae protection: very important for homes in high-humidity areas or with frequent rain

Which brands are worth a look, and how to choose for your home?

In the Thai market, the leading brands all have reliable ultra-premium top grades, such as TOA (SuperShield) , which stands out for durability and heat reflection; Beger (BegerCool) , which focuses on cool-home, high heat-resistance innovation; Nippon Paint (Weatherbond) , known for its flexibility in covering hairline cracks; and Dulux (Weathershield) , which withstands extreme weather. Which brand you choose depends on your budget and the features you care most about, but the most important thing is to choose that brand's highest grade for long-term value.

3 steps for exterior painting that lasts and doesn't peel easily

• Step 1 Prepare the surface: wash off dust and algae and scrape off all loose old paint, then apply an anti-mould solution and let it dry completely
• Step 2 Apply primer: for old walls, use a primer for old plaster (oil-based types adhere especially well); apply 1 coat to bind dusty plaster firmly
• Step 3 Apply the top coat: apply 2 coats of exterior acrylic emulsion paint, letting the first coat dry completely before the second

Safety precautions: Exterior painting, especially on houses of 2 storeys or more, needs scaffolding or proper safety equipment. If you aren't experienced, we recommend using a professional painter for safety and a neat, smooth finish.
