External stairs, especially wooden ones, are generally a characteristic of homes with swimming pools, whirlpools, bridges or raised porches. However, atmospheric agents pose a potential threat and can destroy them over time. The only way to protect these stairs is by waterproofing them. This operation will not only protect them from rain, sun and wind, but also from some insects such as carpenter bees. Waterproofing the external stairs of your home is an essential step in preserving their beauty and resistance. The steps necessary to waterproof the stairs of the house depend on the material from which they are made. Let’s see, through the steps of the following guide, how to waterproof outdoor stairs.
How to waterproof outdoor stairs?
While cement is known to be a strong material, it still requires the application of a sealant for storage. Most concrete sealants and provide a matte finish. For a glossy finish, a sealant is recommended epoxy or polyurethane resin. For wooden stairs, it is necessary to purchase a water-repellent product that prevents mold and deformation.
You will need:
- 1 liter of hot water
- 1 liter of ammonia
- 1 bucket
- Water-repellent paint
- Anti-rust paint
- Pressure washers
- Rotating grinder
- Waterproofing sheath
If the outdoor staircase is masonry, sweep dust and dirt off the concrete using a broom. Look for any cobwebs or leaves in the corners and remove them. Combine hot water with a cup of household ammonia in a bucket. Pour this mixture onto the cement and rub, using a stiff bristle washing brush. Rinse the concrete with clean water. Use a pressure washer if necessary. Allow the concrete to dry completely before proceeding. Otherwise the sealant will appear stained. The ideal solution is to eliminate the old garnish tiles and after having compacted the underlying screed again, cover every single step with the type of sheath used to waterproof the terraces.
If, on the other hand, the staircase in iron or in another metallic material, there are three steps. First, the old paint/anti-rust layer will need to be removed. This first step is extremely simple and can only be boring. In the second phase, it is advisable to make small holes on the steps. This will prevent the formation of stagnant water which quickly spoils the paint and favors the formation of rust. Lastly, it is extremely important to give one or more coats of anti-rust paint. Before proceeding with the laying of the latter, it is necessary to smooth the surface and remove any debris.
Among the types of external stairs, wood is undoubtedly the one most at risk of being damaged due to water infiltrations and damage caused by humidity. The waterproofing can take place like those in iron using water-repellent paints that are generally used for wooden or fiberglass boats that are also very resistant to foot traffic. Another remedy to protect the wood is to make holes to use with drips, or if you are implanting new ones, give each of them a little? of inclination in order to avoid the accumulation of water especially in the presence of heavy rains.
We recommend laying tiles with suitable adhesives and covering the water-resistant joints.
