5 Gal. Ultra Siliconizer 100% Acrylic Elastomeric Reflective Roof Coating (Silicone-modified)

Hi Ka, clean the surface and make sure is out of dirt, grease, oil or any debris; then re-coat the surface to correct the imperfections a let it dry for 24 before expose it to the rain.

Hi Matt, for your asphalt flat roof I would recommend the Lanco Ultra Siliconizer. We highly suggest waiting 24 hours in between applications. When necessary you can prime the entire roof surface with Acrylic Primer Sealer AS-210 at a rate of 250 sq./ft.gal. as this product is specially formulated to penetrate and seal internal cracks and porous surfaces. Then you need to apply two perpendicular coats of the Ultra Siliconizer (recommended product for the asphalt roof), at a rate of 50 sq./ft. per gallon.

Hi sox2014, the brand that you can use is GRACO, just make sure it is not electric but gas. The most important thing is that the machine needs a pump with 1500-2000 psi on a pump also 1-2 gallon delivered per minute.

I wouldn't know about spraying in on, it's very thick, almost a gel.I rolled mine on by dumping and spreading it with the roller.

Hi Ted, the Ultra Siliconizer which is 100% acrylic, has the enough amount of silicon to make it waterproof and seal your roof, but with the advantage of any 100% acrylic roof coating which allows you to paint on top and re-coat in a future with any acrylic elastomeric product.

That is not recommended. I think it causes the shingles to become brittle.

I'd say 250 sq.ft. but I put it on really thick with a roller.

Hi Sagebrush, Ultra Siliconizer™ is a single component 100% acrylic silicone elastomeric for roofs and walls with outstanding adhesive properties that will provide a thick, high performance, water and weather resistant seal on most surfaces, usually without need of a primer coating. The recommend coverage is 50 ft.2/gal. (4.65 m2/gal.) @17 dry mils, 32 wet mils per application and we recommend two applications.

Hi Ernie, the Ultra Siliconizer™ is a premium high solids, 100% acrylic roof coating modified with a very small amount of silicone, that adheres tightly to most roofing substrates and provides a long lasting water and weatherproof seal. It has excellent energy savings properties due to its sun and heat reflectance. Miami-Dade County approved. But our recommendation is to use Aqua-Proof™ Primer which is a monolithic membrane made of styrene/butadiene latex that provides an easy alternative for many waterproofing applications as a base or primer. Aqua-Proof™ performs best when used as a primer over existing surfaces and tested extremely well during continuous water immersion. It waterproofs concrete and protects from silage attack. You can also use over wood, but you always have to topcoat in which case you can use the Roof Coating, paint, stucco or thin set and tile. It's a great product.

Hi Vardo, unfortunately we recommend not to use the Ultra Siliconizer on a plywood previously treated with water sealant.
