What is Single-Component Polyurethane with Hardener WP210?

Before using Polyurethane WP210, ensure that the desired surface is primed with a layer of Polyurethane Primer WP200. (100 grams per square meter). For freshly prepared concrete, wait 14 days before applying. The surface must be clean, dry, and free of dust, grease, and any contaminants. The substrate should be cleaned of any loose layers using various mechanical methods, including sandblasting. To achieve better adhesion and higher product quality, the concrete surface should be scratched with a grinder or scraper and then cleaned of dust particles using a broom. An air blow and suction system can also be used at this stage. Before applying Polyurethane WP210, any joints, cracks, and holes on the surface should be repaired. Depending on the size of the hole or crack, you can use different sealants and adhesives produced by Mandana Polymer to repair and seal them. For stone surfaces, ensure that the surface is clean, dry (moisture below 4%), and free of dust, grease, and any other contaminants. The substrate should be cleaned of any loose layers using methods like sandblasting.

How to Use Single-Component Polyurethane with Hardener WP210?

Step 1: Surface Preparation for Applying Polyurethane WP210

Before applying Polyurethane WP210, ensure the surface is primed with a layer of Polyurethane Primer WP200. (100 grams per square meter). For freshly prepared concrete, wait 14 days before applying. The surface must be clean, dry, and free of dust, grease, and contaminants. The substrate should be cleaned of any loose layers using sandblasting or other mechanical methods. To improve adhesion and product quality, use a grinder or scraper to roughen the surface, then sweep away dust particles. An air blow and suction system can be used to assist in cleaning. Before applying Polyurethane WP210, any joints, cracks, and holes on the surface should be repaired with the appropriate sealants and adhesives from Mandana Polymer. For stone surfaces, ensure that the surface is clean, dry (moisture content below 4%), and free from dust, grease, and contaminants. Clean any loose layers using sandblasting or other mechanical methods.

Step 2: Pre-Application Control and Recommendations

Stir the contents of the container gently for 3 minutes and wait for any bubbles caused by mixing to dissipate.

Then apply Polyurethane WP210 to the desired surface using a brush or roller.

Depending on the surface’s size and porosity, the required amount of material can be calculated. 500 grams of Polyurethane covers 1 square meter of a non-porous surface completely. The required amount should be applied in two stages to cover concrete and mortar surfaces.
