Concrete Stripping and Sealing

There are two general types of concrete stripping: mechanical concrete stripping and chemical concrete stripping. Mechanical concrete stripping involves the use of equipment that perform shot-blasting, sandblasting, grinding and scarifying. The most popular technique used by professionals is grinding. Chemical concrete stripping is by far the most common method of removing concrete sealants. It can be made safe for the environment and often leaves lesser marks than mechanical means on finished concrete.

Concrete sealers are fast and cost-effective against mould, petrol, and oil. In general, it is recommended to get professional sealers particularly if you want to enhance colours, and apply fast dry sealers.

Concrete stripping and sealing specialists know that preparation is critical for a longer concrete seal lifespan; bad “bonding” may result in common defects such as peeling, discolouration or worn areas. In addition, sealing of floors is only as good as the preparation underneath, a floor showing signs of delamination or a sealing being worn will require an expert approach to guarantee proper remediation and longer lifespan.

Yes, it is important to protect your concrete floors for the long-run with professional concrete stripping and sealing. Sealed concrete also has a richer color and a glossy sheen can be added if desired.

Before sealing concrete, it is important to remove all oil, grease, stain, dirt and dust, as well as strip any existing sealer in the surface. Next, an etching solution is applied to open up the concrete. The sealer is applied in multiple coats and allowed to fully dry. To ensure it is done properly, it is recommended to hire a concrete sealing professional to do the job.
