Epoxy Cementitious Flooring
A study found that around 80-85% of epoxy/PU floorings failure is due to the high level of moisture content in the concrete or rising moisture. RC Corrocare Industries’ epoxy cement flooring offers a solution to tackle and eliminate failure due to moisture content in concrete by using a temporary moisture barrier epoxy screed. The percentage of failures due to faulty materials and bad workmanship is very low. Our epoxy coating applied on cement floors provides excellent performance, offering a smooth and durable surface that can withstand heavy loads for many years.
The moisture content of concrete before applying any regular epoxy or PU floor coating needs to be ≤ 4%. Typically, it takes around 28 days for concrete to reach the permissible moisture limit of ≤ 4%, though this timeframe may vary depending on air pressure and other climatic conditions. In some cases, even after 90 days, the moisture content remains high due to the high water table beneath the concrete.
If epoxy/PU coatings are applied on concrete surfaces with moisture levels > 4%, blistering or bubbles can occur due to osmosis, which is the passage of water from a high water concentration area through a semipermeable membrane to a low water concentration area.
RC Corrocare Industries’ epoxy cementitious flooring typically consists of resinous material combined with fillers, which include resin, hardener, and cement-based specially formulated aggregates. These are mixed onsite with a variable-speed stirrer and applied within the specified time frame. Cement epoxy coating is applied at thicknesses ranging from 2mm to 100mm depending on the user’s needs. Since these are temporary barrier screeds, a topcoat is advised to provide aesthetics and other functional properties, which can be achieved by regular epoxy or polyurethane floor coatings.
