What is better elastomeric or silicone?

Longevity. Many factors can affect the longevity of an elastomeric coating, but mil for mil, silicones last longer than acrylics. This is mostly due to the inherently superior UV and moisture resistance of silicone materials.

What is the difference between elastomeric and silicone?





Silicone is an appropriate coating for polyurethane foam roofs. It can resist some types of weathering and is effective for applications that require multiple coats. Elastomeric coatings have elastic properties, so they do not crack easily.

Is elastomeric roof coating the same as silicone?

Quote from the video:
Quote from Youtube video: Silicone. Will last for many decades after a disciplic coatings are not the same. For an average application an acrylic coating may last up to ten years before the sun's UV rays deteriorate.

How long does elastomeric coating last?

10-20 years

But how long do elastomeric roof coatings last? Elastomeric roof coatings will perform for 10-20 years depending on the initial application thickness. For a 10-year warranty, 20 mils of elastomeric roof coating will need to be applied.

What is silicone elastomeric?





Silicone elastomers



Silicone rubbers or elastomers are a range of heat stable elastic silicone materials used for electrical insulation as sheet, tape, wire and cable coverings, extruded sleevings and mouldings, unsupported, but more extensively as coated glass-fibre cloths, tapes and braided glass sleevings.

Is silicone good for roofs?

Silicone roof coating systems are great alternatives to replacing your roof system. You can restore your commercial roof to working condition in less time, with less cost, and while keeping your building under warranty.

What will silicone not stick to?

Mold Release



Generally, silicone RTV mold making rubber does not stick to anything, and nothing will stick to it. The exception is that it will stick to itself, other silicones, silica, and glass.

Where is elastomeric paint used?

One of the best reasons to use elastomeric paint is that it places a secure coating on the surface you are painting. This coating creates a barrier so that moisture is unable to penetrate the walls. This will work well on surfaces such as masonry, stucco, poured concrete, roofs, bricks, wood, and metal.

What is the difference between elastomeric and acrylic paint?



For exterior painting, acrylic and elastomeric paints are among the most popular paint types to use due to their flexibility and resistance to the elements. In terms of basic differences, acrylic is a resin type and is usually thin and strong, while elastomeric, a property of paint, is thick and strong.

Can you paint over elastomeric coating?

Weathered elastomeric coatings may be refreshed by application of a quality exterior acrylic latex paint. Proper surface preparation must be done and the paint applied under appropriate conditions.

Can you roll elastomeric paint?

Elastomeric Coating is easily applied with brush, roller (3/4” Nap Roller recommended) or suitable spray equipment.

How long does elastomeric paint take to dry?



Dries to the touch in 4-6 hours. Longer dry time required in cooler temperatures and higher humidity. Allow 24 hours between coats. After two weeks, cured paint film may be cleaned with a mild, non-abrasive liquid detergent.

Does elastomeric paint need primer?

Do You Need Primer With Elastomeric Paint? Almost any structure can be coated with an elastic film that is durable, tough, and waterproof. It is imperative that the imperfections are completely filled with primer and paint or water will penetrate underneath the finish and cause peeling.

Is elastomeric paint waterproof?

Advantages to Elastomeric:



Waterproofing properties – Elastomeric paint can provide a waterproof system to the home if specifications are followed. Protects from wind driven rain – Strong wind driven rain can harm paint coatings. Elastomeric paint is designed to withstand this more so than typical house paints.

How many layers of elastomeric are there?

Always consult the manufacturer and instructions for exact application recommendations, but in general you should plan on giving your roof at least two coats to achieve a minimum of 20 dry mils thickness.

Is one coat of elastomeric paint enough?



Elastomeric paint doesn’t need multiple coats. With two coats of elastomeric paint over an excellent primer, the cracks will be filled and water will be unable to penetrate.

Can you paint elastomeric paint over elastomeric paint?

So to summarize, elastomeric coatings may always be used over top of existing elastomeric paint, but even a high-grade elastomeric will only last 10 years, give or take.

Can you sand elastomeric paint?

Sand the surface with 220-grit sandpaper. The trick to good adhesion is roughing up the smooth elastomeric finish. On a slick surface, paint tends to drip easier and provide only spotty coverage. Sandpaper helps make the surface more callous for easier painting.

What is the difference between elastomeric paint and elastomeric coating?

Density – The paint is up to ten times thicker than regular paints, and when it is dry you can notice the difference. Elastomeric coating contains up to twenty mils each coating compared to a regular paint, which reaches only about three mils for each coat applied. An excellent example to look at is tarps in a store.

Can I use elastomeric paint indoors?



It can be applied with a brush, roller, pad, or sprayer. Can be used indoors or outdoors.
