While you may not want concrete floors in your home or your business, most buildings are currently constructed with concrete floors. This does not mean, however, that they have to stay. Whether you install a wood-like covering or a carpet, the concrete floors offer excellent and cost-effective coverage for your home or business.

If you want to put in carpeting over your concrete floors, the process is pretty straightforward. This is a typical project that many home and business owners undertake to make their buildings more cozy and liveable. Concrete floors, while structurally sound, can often be unpleasant visually. While you can polish them and enhance their aesthetic appeal with decorative concrete systems, the floors will remain cold and more suited to an industrial or retail environment.

If you want to install carpet over your concrete floors, it is important that you properly seal the concrete slab over which you will be applying the carpet. Without a proper sealing process, the concrete could potentially let in water that would seep under the carpet and lead to a number of potential problems. The easiest and most cost-effective way to deal with this would be to apply a concrete sealer like the Lithi-Tek 4500 primer, which is a penetrating sealer designed to react chemically within the concrete. These chemical reactions will densify the concrete, making it structurally stronger by filling in the various pores and cracks in the concrete. It will also help lock out harmful gases and water from poring through your concrete.

Next is it best to wait seven days and then apply the Siloxa-Tek 8500 as a topcoat. The combination of the two products is going to prevent as sort of water or moisture from traveling through the concrete in order to adequately protect carpet damage. You then want to wait another 7 days before applying carpet over the sealed surface. A properly sealed concrete floor will ensure the carpet remains dry and in optimal condition, at least from below.
