Your Ultimate Guide to Applying Elastomeric Paint

applying elastomeric paint

Elastomeric paint is a very durable and waterproof coating. It works great for outdoor surfaces that are exposed to the weather. Unlike regular paints, elastomeric paint can stretch and compress without getting damaged.

Applying elastomeric paint can be tricky, so it’s best to get help from a professional. Even though you don’t need special tools, proper application takes experience. You need to know how to prepare the surface, get the paint at the right thickness, and apply it evenly.

A professional will be able to do all of this correctly to give you a smooth, long-lasting finish for your outdoor project. Their expertise is important for getting the best results with elastomeric paint.

First, What is Elastomeric Paint?

Elastomeric paint is a type of paint that has high elasticity and can stretch and move with the surface without cracking or peeling. A combination of elastic polymers, pigments, and solvents makes up its composition. The elastic polymers, typically acrylic or silicone, give the paint its elasticity. It can stretch and move with the surface.

The paint is best for the outdoors. Elements such as wind, foot traffic, or snow. Areas prone to movement or expansion and contraction due to changes in temperature and moisture. Elastomeric paint is also known for its durability and waterproofing qualities, making it an excellent choice for a long-lasting finish. Use it on stucco, concrete, masonry, and metal surfaces. It can be applied with a brush, roller, or sprayer.

Pigments provide color, and solvents act as a painting medium and help ensure even application. The exact composition of elastomeric paint can vary depending on the manufacturer and the specific type of elastomeric paint. Some elastomeric paints may also contain additional ingredients, such as UV inhibitors or mold inhibitors, to enhance their durability and resistance to environmental factors.

Preparation

Properly preparing the surface is necessary for successfully applying elastomeric paint. You need a clean, smooth surface for the paint to bond well and last a long time. Before applying the elastomeric paint, you need to remove any dirt, grime, or old paint. Use a quality detergent that won’t leave behind any residue. You may also need to use a scraper or pressure washer to remove any peeling or oxidized paint. If you don’t properly prepare the surface, the paint won’t adhere well. This can lead to the paint job not lasting and not looking as good as it should. Taking the time to thoroughly prepare the surface is essential for a successful elastomeric paint application.

Filling cracks in stucco or masonry before applying elastomeric paint is important in ensuring a smooth and attractive finish. Small hairline cracks can easily be covered with elastomeric coatings without much hassle. But, larger cracks, greater than 1/16″, should be filled with a compatible substance. Use mortar or patching cement to prevent the paint from settling into the crack and creating an unsightly appearance. Use fiber-reinforced tape for cracks that are not expected to spread. This can bridge the gap and provide additional stability. It is important to take the time to properly address any cracks in the surface before applying elastomeric paint.

Priming

Before applying elastomeric paint, it’s important to follow the manufacturer’s instructions. This includes using the right primer and preparing the surface properly. The preparation needed will depend on the surface – things like unpainted blocks vs. previously painted wood will require different steps. Choosing the right elastomeric paint formula for the surface is also key.

Elastomeric paint doesn’t soak deep into the surface, so using a primer is often necessary to help the paint adhere well and last a long time. Following the manufacturer’s guidelines for primer and surface prep is very important. Taking the time to properly prepare the surface and apply the primer will help ensure a successful, long-lasting elastomeric paint job.

Application

Properly applying a product is essential for getting good results. Following the manufacturer’s instructions is the best way to ensure a high-quality outcome.

One important factor to pay attention to is the wet film thickness and dry film thickness. These measurements can indicate how well the product was applied. Monitoring the wet and dry film thicknesses can help you know if you’re applying the product correctly according to the manufacturer’s guidelines. This is an important step in achieving the best possible results.

Both WFT and DFT are important factors to consider when applying paint. They affect the final appearance and performance of the paint. If the WFT is too high, it can result in runs or drips. A too-low WFT can lead to an uneven or thin coating. Follow the recommended DFT to ensure proper coverage and durability.

WFT

Wet film thickness (WFT) refers to the thickness of a paint in its wet state, immediately after application. It is measured in mils (thousandths of an inch) or micrometers.

DFT

Dry film thickness (DFT) refers to the thickness of paint after it has dried completely. It is also measured in mils or micrometers and is the final thickness of the paint layer that remains on the surface after drying.

Staying within the recommended values for each item is important. It directly affects the performance and lifespan of the product. Opting for multiple thin coats instead of a single thick coat is usually the better choice. This ensures an even coverage without the risk of sagging or appearing lumpy. In conclusion, following the manufacturer’s instructions and paying close attention to the film thickness is the key for a successful application.

When painting, it is important to properly cover all surfaces, including difficult-to-reach areas around pipes, windows, and electrical boxes. Use a brush to apply paint to these areas precisely. Use a thick nap roller in an overlapping “V” pattern for larger, flat surfaces to cover the area efficiently. While airless sprayers can be used, they require specific equipment, special-sized spray tips, and professional training. This may not be available to the average do-it-yourself homeowner. So, a brush and roller may be a more practical option for DIY projects.
