When preparing a floor, the covering material is not going to look or perform its best when the substrate is not prepared adequately. With a range of patching products that can help prepare substrate on the market today, it’s important to know the pros and cons of each type. Gypsum-based patches are a common choice for contractors today.
Why Gypsum-based Patches?
A gypsum-based patching compound is the top choice for many contractors that are looking to repair depressions or holes. It sets quickly, doesn’t shrink and is easy to apply. Gypsum-based patch can be used on concrete, wood, masonry and even in drywall and prepares the surface for all kinds of flooring, such as wood, carpet, and more. Floor coverings will always look their best and last longest with proper substrate preparation.
Prepping For Patches
To use gypsum-based patches properly, the surface must by dry, clean, and free of oil, dust or paint. The surface must also be crack-free and stable. It’s never a good idea to take a shortcut with patches that are intended to repair substrate imperfections. Patches are designed to repair or fill in any imperfections in the substrate. Gouges, ridges, seams, depression and other flaws are covered with the patching material, creating a smoother surface. Of course, with any product, there are certain factors to watch out for when using gypsum-based patching compound.
Here are just a few of the most common problems encountered when using gypsum-based substrates improperly:
- Moisture problems
- Adhesion problems
- Break or crumble under heavy loads
When flooring contractors and flooring installers are completely aware of the advantages and disadvantages of using gypsum-based patches, they will be able to make the best choice for each job they have.
