How to waterproof a terrace and why you should do it

Today, enjoying a home with outdoor spaces is a true privilege. However, these spaces also require careful and necessary maintenance to ensure they are fully optimized and ready to be enjoyed. One such example is waterproofing a terrace, preventing leaks and dampness from reaching the interior. Today on Deco and Lemon, we'll tell you how to achieve this and why!

What does waterproofing a terrace mean?

Waterproofing a terrace is a process based on applying a layer to the surface and/or walls . This prevents water from penetrating the interior of the building , and is generally necessary because the materials used in exterior construction do not usually have these insulating properties.

In other cases, direct exposure of the exterior to certain weather conditions also leads to wear and tear on the cladding. For this reason, it is advisable to waterproof the area around 20 years, depending on the maintenance that has been carried out.

Considerations for waterproofing a terrace

There are different solutions when it comes to waterproofing a terrace or rooftop, which will vary depending on several factors:

Waterproofing needs to be more airtight when the house is located in an area with high humidity levels throughout the year.

Before applying any product (which must be specific), it is important to address the needs of the surfaces that may cancel the effect of this process , such as mold.

Finally, it is essential to conduct an on-site analysis and determine which treatment is the most appropriate and effective .

Paint for waterproofing a terrace, the simplest option

The easiest and most effective alternative is waterproofing paint . Simply apply it to the entire area you wish to seal, paying particular attention to the joints, as these are the areas most prone to leaks . Using this paint creates a film that prevents water from seeping in.

Other options for successfully waterproofing terraces

Beyond paint, there are numerous other options that aim to successfully waterproof a terrace:

Liquid polyurethane. A product very similar to the previous one, but it is in a liquid state across the entire surface. It is widely used, especially on small terraces.

Asphalt fabric. Roll composed of oxidized asphalt bitumen and fiberglass that must be heat-sealed to the surface.

EPDM membrane (ethylene propylene diene rubber). A material with total wear resistance and especially used for large surfaces due to its presentation.
