Elastomeric Waterproofing is the sort of paint to use if you’re painting a building and require a color that produces a moisture barrier. Even though elastomeric paint hasn’t been around as long as other paints, it’s become one of the most popular coatings for industrial, commercial, and residential structures since the late 1950s. If your building is in a location where moisture is a constant problem, you’ll want to learn more about elastomeric paint.
What Is Elastomeric Coating and What Does It Mean?
Elastomeric coatings, often known as wall paints, are protective barriers applied to both interior and exterior walls. Water-based coatings and paints, as well as acrylic latex paints, are examples of Elastomeric Waterproofing. A latex coating or acrylic latex is another name for an elastomeric coating.
Elastomeric coatings, also known as acrylic resin coatings, are latex paints with a milky hue while wet and become flexible, elastic, and translucent after drying. On concrete buildings, they are applied as a thick layer.
Elastomeric Waterproofing Material is ideal for painting buildings that require moisture-resistant paint. Exterior features such as concrete walls, roofs, and floors are commonly coated with Elastomeric Waterproofing. However, they should not be used on wood siding or logs that need to breathe since any crack in the layer allows moisture to seep into the wood, causing rotting, mould development, and other problems.
What does Elastomeric Waterproofing Coating do?
Elastomeric Waterproofing provide the following functions:
- Avoid chalking, cracking, blistering, peeling, flaking, and flaking.
- Color that lasts a long time.
- It dries rapidly and has a low odour.
- Solvents and bacteria are resistant.
- Stick to it tenaciously.
- When applied to surfaces, it dries smooth.
- When the coat dries, it closes the open pores in the concrete.
What are the Types of Elastomeric Waterproofing Membrane?
1. Elastomeric Acrylic Coatings
Acrylic elastomeric coatings are water-based and are applicable on sloped roofs. If water does not flow off an acrylic top, the elastomeric waterproofing coating will dilute, change back to a fluid, and wash away.
Acrylic Elastomeric Waterproofing are made up of around 52 per cent solids and 48 per cent water by volume, so nearly half of the product is lost to evaporation when applied. They are, nevertheless, less expensive than many other elastomeric coatings, partly because you’ll need to use a lot more product to compensate for what evaporates.
2. Elastomeric Silicone Coatings
Silicone elastomeric coatings are silicone resin-based coatings with a solids content of 96% and a carrier content of 4%, which means they won’t wash away as an acrylic coating would.
Flat roofs benefit from this sort of Elastomeric Waterproofing because it can handle standing water. They’re in the middle of the pack in terms of performance and cost, and they’re twice as weather resistant as acrylics. They are, nevertheless, more costly than acrylic Elastomeric Waterproofing.
3. Elastomeric Coatings Made of Urethane
Compared to silicone and acrylic coatings, urethane Elastomeric Waterproofing are more impact-resistant than any other Elastomeric Waterproofing available. However, they are pretty costly.
How Are Elastomeric Coating Used?
- Step 1: Gather Appropriate Tools and Equipment Because the correct tools make applications more accessible and faster to complete.
- Step 2: Clean and Apply Pressure Roof cleaning The importance of preparation in coating application cannot be overstated. The roof must be clean, dry, and structurally sound before applying the coating.
- Step 3: Repair and strengthen the roof. Before applying the elastomeric roof coating, rectify all areas of damaged areas.
- Step 4: Perform a Field Adhesion Test. Then, do a field adhesion test on the roof to determine which primer (if any) is required.
- Step 5: Combine and stage roofing materials. To ensure optimal application, properly mix all Polygalas materials, including the elastomeric roof coating.
- Step 6: Set up the spray equipment and start spraying. To apply the coating, utilize airless spray equipment with a minimum volume per minute of 3/4 gallon and a minimum pressure of 3,300 p.s.i.
What are the Advantages of Elastomeric Paint?
- It’s simple to apply using a roller or a brush.
- Flexible can bridge fissures.
- Protective – acts as a barrier against salts and gases in the atmosphere.
- High-build – hides flaws in the substrate.
- Waterproof – protects concrete from salts carried by the water.
- UV-resistant – keeps its appearance.
There are Several Disadvantages to be aware of.
The use of elastomeric paint or coating has a few drawbacks. The first is that it is prohibitively costly. It may be up to 50% more expensive than regular paint, but it covers considerably better. Elastomeric paint is more difficult to deal with than ordinary paint since it is so different. It can also create unpleasant lumps in your finish if not applied correctly.
Getting to the Required Level of Performance
An adequate film thickness is essential to ensure that elastomeric roof coatings operate well. This is to guard against UV deterioration since coatings with insufficient film thickness may not be able to filter UV rays and bridge fractures effectively. When this happens, the color behind the layer begins to show through, making the white coating seem grey if placed on a dark surface.
At a minimum of 20 dry film thickness, elastomeric roof coatings can achieve the physical qualities indicated in the technical data sheet (TDS) (DFT).
