As temperatures rises in summer, majority of families in Pakistan start worrying about heatwave and they start thinking how to control temperature of their home inside. To control temperature of home the key factors are walls and roof. People try different techniques to protect themselves from heat. Recently some YouTube influencers tried to convince people that use of Plaster of Paris (POP) as a heatproofing solution is the most effective and cheapest solution. We will discuss the pros and cons of its use.

The Myth of POP for Heatproofing

Plaster of Paris is a powder based chemical used for filling of holes in walls, however not meant for thermal protection. Its use in outdoor environments, particularly on rooftops, raises several serious concerns:

  • Moisture Absorber: POP is highly porous and absorbs water easily. Once dried and exposed to rain, dew, or even humidity, it begins to soften, crack, and wash away.
  • Not weather-resistant: In heavy rains, the POP layer breaks down and wash away.
  • Lacks adhesive strength: Unlike acrylic POP does not bond well to cemented or metallic surfaces in the long term, making it unsuitable for permanent outdoor application.

A Smarter, Durable Solution: Advanced Chemical Heatproofing

Instead of risking unreliable results with POP, modern chemical heatproofing solutions offer advanced protection and durability. The best companies in the field are now using a scientifically formulated blend of powerful materials, including:

  • Titanium: Enhances UV and thermal resistance, helping to deflect heat and maintain cooler indoor temperatures.
  • Nitro Sole: It is rubberized material increasing not only bonding with surface but due to its flexibility it reduces the risk of cracks.
  • Calcium Carbonate: It is filling material that increases  thickness and density, increasing the coating’s ability to act as a heat insulator.
  • Acrylic Binders: It is very strong adhesive material,  famous for its elasticity, and long life against strong weather conditions.
  • Ammonia Liquid MEG: It increases  chemical stability and avoids microbial growth.
  • Taxanol: It enhances  application flow and ensures a smoother, more even finish just like wall paint.

These chemical coatings are designed specifically for rooftops, terraces, and exterior walls and offer benefits that POP simply cannot match.

Why You Should Switch to Chemical Heatproofing

  • ✅ Waterproof and Heatproof: Give the advantage of 2 in 1. In the expense of heat proofing gives the protection of  waterproofing as well without extra charges.
  • ✅ Long Lifespan: Chemical based solution works for 5 to 10 years.
  • ✅ Eco-friendly and Safe: All of the above mentioned ingredients are non-toxic and environmentally friendly.
  • ✅ Cost-effective in the long run: If cost is divided of number of years it works then solution is very economical in long run.

Conclusion

Plaster of Paris is not designed for external weather exposure and fails quickly when used for heatproofing. If you’re looking for a smart, durable, and effective solution, chemical-based heatproofing using materials like titanium, acrylic, calcium carbonate, and Taxanol is the right choice. Don’t be misled by temporary fixes — invest in professional chemical coatings for real, lasting relief from heat.

For expert heatproofing with proven materials, always choose a reputable company that uses modern formulas — because your comfort, safety, and savings matter.
