Our UV Protective and Power Saving Top Coat is the ultimate solution for all your outdoor coating needs! This high-performance top coat is specially formulated to protect your surfaces from harmful UV rays while also reducing energy consumption.

Our top coat is made with advanced UV-absorbing technology that blocks out harmful UV rays, keeping your surfaces looking fresh and new for longer. It's perfect for use on outdoor surfaces such as roofs, decks and patios.

In addition to providing UV protection, our top coat is also designed to help save energy. Its advanced formula reflects the sun's rays, reducing the amount of heat absorbed by your surfaces and helping to lower your cooling costs.

Our top coat is easy to apply, and dries quickly to a durable finish. It's also resistant to chalking, fading and cracking, making it ideal for harsh outdoor environments. It's perfect for homeowners and contractors looking for a long-lasting and energy-efficient coating solution.

Before application, you need to ensure to apply a layer of Sealer / Primer on any surfaces including previously painted surfaces, or Rust Inhibitor Primer on any raw metal surfaces as well as over your cured Waterproof Sealant to promote adhesion for the application of the Thermal Coating.

Pair this Protective Top Coat with our Waterproof Sealant and create the ultimate dual-layer waterproofing membrane!

APPLICATION - If applying in cooler temperatures, ONLY apply in the middle of the day to allow the product to fully cure. If rain is imminent, DO NOT apply Thermal Coating to the surface.

**NOTE** - Ensure to use Sealer/Primer or Rust Inhibitor Primer prior to applying Protective Top Coat to any surface.

WARNING!! - Product NOT to be immersed e.g. Water tanks, ponds, gutters, or any ponding water.

Top coat

I have not finished yet but I am hoping it will be extremely affective

Vadim Weisbek
My shed roof is saved!

I highly recommend the UV protective top coat that I recently used. I had been considering replacing my shed roof due to age and condition, but after applying the top coat, I'm confident that I won't need to for at least 10 years.

Not only did the top coat help to reduced the temperature in my shed, but it also provided excellent UV protection, which is important for maintaining the integrity of the roof. The application process was straightforward, and I was able to do it myself with no problems.

Overall, I'm very happy with the results and would highly recommend this product to anyone looking to protect their roof and save money in the long run.
