A damp proof membrane, or DPM, is a barrier that is placed between a concrete subfloor and a wood floor. DPM prevents moisture from passing from one level to another. DPM is effective in resolving existing damp issues or prevent future problems. Before laying a wood floor on concrete, it is crucial that you measure the moisture contents of your subfloor. Although you can use DIY methods to measure the moisture content, an approved hand-held meter is the most reliable. If you have hired a professional to do the work for you, your wood flooring fitter will likely measure the moisture content of your subfloor. However, do not assume that they will measure the moisture content. Follow up and ensure that they do.
Floor manufacturers often provide their acceptable moisture level guidelines. Nevertheless, you may be required to install a DPM to ensure that you avoid damp problems. In some cases, even when the moisture content is low, you can install a DPM to avoid future damp issues. Here are some instances when to use a liquid DPM.
Damp Floor treatment
Moisture rising through a concrete floor is not a new thing. This moisture causes damp issues on carpets, warping wooden floors, and leads to the growth of low-level mold. Constructors often use a thin damp-proof membrane when building, but it is torn quickly, rendering it ineffective. As such, installing a DPM on top of a concrete slab ensures the completion of sensitive floors. Liquid DPM provides a perfect barrier without raising the floor level. Make sure that the surface is well prepared before using liquid DPM. Any traces of grease or dust particles can affect the durability and effectiveness of the coating. Use procedures such as power cleaning or acid etching to prepare your surface.
Damp Walls Treatment
A damp wall can ruin your decorations such as curling wallpaper, and paint. The primary impact is that it affects the atmosphere of your home by turning it from welcoming to uninviting space. A damp wall will also increase the cost of running your home. Liquid DPM can help you resolve your damp walls problem. Install the DPM on the internal walls after fixing the source of the damp. The membrane creates an air gap that allows moisture to evaporate from behind the wall.
Damp Roof Treatment
You can also use liquid DPM for low-water-permeable roofs. Concrete roofs are often the most affected and may allow moisture to pass through to your house. Using liquid DPM will help you save the investments in your home.
Clearly, using liquid DPM is crucial and advantageous. Make sure that you wear protective clothing when using liquid DPM. You should also read the manufacturer’s instructions on how to apply your liquid DPM to avoid any problems. Additionally, seal all the joints and cover any holes with tape. You should also avoid piercing the membrane when working with equipment such as pipes. See this page for more information on Damp Proof Membrane.
