Your walls and your floors, or you can undertake this task yourself. Although a number of serious cases of cracks would require you to call in an expert, minor cracks in your basement or on your concrete slabs can be easily fixed by using a polyurethane Sealant.



Polyurethane is an organic compound that has excellent corrosion and moisture resistance qualities. Further, polyurethane is also effective as a heavy duty adhesive and is ideal for coating. It is for this reason that polyurethane sealants are widely preferred for repairs and waterproofing in both commercial as well as domestic sectors. Apart from its heavy-duty adhesive and waterproofing properties, polyurethane is also renowned for the flexibility it offers when applied over joints.

This flexibility comes in handy while using over concrete joints since concrete expands and contracts due to temperature changes. If a concrete crack is not treated in time it would get worse and could result in significant damage in the future. What makes a polyurethane sealant more effective while fixing cracks in concrete is that it is generally applied using a caulking gun. This makes it significantly easier to fill in the cracks with the sealant, thereby resulting in effective repairs.



Polyurethane sealants are also ideal to repair cracks in wood floors due to its various benefits. Polyurethane offers excellent abrasion resistance as well as scuff resistance, thereby making it ideal for use on wood. The use of a polyurethane sealant on wooden floors will ensure an effective waterproof and water resistant layer.



Polyurethane sealants have very high viscosity and can easily seep into even the minutest cracks to form an effective and waterproof seal. This is especially effective in case you find minor cracks in your basement wall. Although, a crack in the basement wall could be due to improper foundation, but in case you find that it is not a foundation crack you can easily use a polyurethane sealant to fix the problem. Further, since a polyurethane sealant can easily expand and contract, your basement crack will be effectively sealed and will remain waterproof for a long time.



A high quality polyurethane sealant will effectively adhere to different surfaces such as wood, masonry, concrete, steel as well as aluminum. The polyurethane seal will remain flexible as well as corrosion resistant for a long time. You can even paint over a polyurethane seal to ensure that the aesthetics of your house are not affected in any way. It is due to the excellent adhesion qualities as well as the other additional benefits that are offered by a polyurethane sealant that these are becoming the preferred choice for home renovation and repair work.
