Waterproofing different areas of your home and especially the patio/deck area is a very popular trend that can make a huge difference for your household. By waterproofing these spaces, you can improve their durability, prevent element tear and wear and even save more money on repairs in the long run. There are different waterproofing system available, but waterproof paint is the most popular choice. Your Langhorne handyman will explain how to choose waterproof paint properly.


Types of waterproofing systems

There are several types of systems that can prevent water and moisture getting into structures; from solid drop-down elements to paint, mixtures and gels. In the first group, prefabricated rolls and membranes are the most common. Still, they also adhere to the concrete through liquid systems or complements.

To choose the best waterproofing system, you must take into account the surface for application, as well as the environmental conditions and traffic requirements. The budget is also an important factor, as systems vary widely in this regard.


Acrylic waterproofing paints

Called “elastomeric acrylic waterproofing”, these are the most popular domestic systems for their simplicity and practicality in the placement. You can apply the paint on the clean and dry surface, without cracks or breaks. No more than two layers are usually necessary.

Due to the viscosity of the product, the application is possible on flat and horizontal surfaces, but inclined levels, too. They have the advantage of not requiring other complementary systems and have an aesthetic finish in itself. It’s possible to use them on roofs, sheet roofs, and facades in galvanized, concrete or ceramic sheets and stones.

In addition to waterproofing the surface, this type of waterproof paint also has thermal insulation properties. But its biggest drawback is the sensitivity to sharp elements, so it’s not the best choice for high-traffic surfaces.


Asphalt waterproofing paints

Called “asphalt emulsion waterproofing”, these paints are great for residential and industrial buildings alike. The cost is somewhat higher, but very effective for both dry or wet surfaces. They adapt to hot, cold or temperate climates alike.

If you choose waterproof paint of this category, you can use it to treat ceilings, roofs, balconies, patios, foundations, ducts, pipes, sanitary registers, and walls in the subsoil. Its advantages are rapid placement, without special tools, and a high economy in small surfaces application.

For disadvantages, it’s important to mention the need to complement with other systems (mainly acrylic or reinforcing fabrics), and the high predisposition to cause air blisters when reinforced with these extra elements, which can burst and make the waterproofing vulnerable.


Cement waterproofing

Although this isn’t paint in itself, this system of cement preparation is the go-to choice to treat surfaces subject to immersion (cisterns, swimming pools, tanks, foundations, and piles). It’s ideal for filling and preparing cracked surfaces, due to its viscosity. It’s possible to place them in the preparation of the mortar and concrete to reinforce these surfaces. The disadvantages involve its high cost and the necessary experience for its placement.


Epoxy and polyurethane waterproofing

The epoxy and waterproof polyurethane paints have high impermeability and are very resistant to friction. Therefore, they are great for surfaces of high traffic and climatic rigor. These include roofs, industrial pavements and similar. They have an aesthetic finish and can provide different textures, so they don’t require other coatings on top. The disadvantage is its high cost, as well as the necessary experience for installation.
