Method of Application

Application conditions

Substrate Quality

The concrete substrate must be sound and of sufficient compressive strength (minimum 200 Kg/cm²) with a minimum pull-off strength of 15 Kg/cm². The substrate must be clean, dry, and free of all contaminants such as dirt, oil, grease, coatings, surface treatments, etc. If required, apply a test area first. In case the application is on green/ damp concrete, ensure that there is no standing/ponding water on the surface.

Substrate Preparation

Concrete substrates must be prepared mechanically using abrasive blast cleaning, scarifying, or grinding equipment to remove cement laitance and achieve an open-textured surface. Remove weak concrete and expose surface defects such as blowholes and voids. Repairs to the substrate, filling of blowholes/voids, and surface leveling must be carried out using appropriate products. Ensure that the dust, loose and friable material is completely removed from all surfaces by brush and vacuum before application of the product. The concrete substrate has to be primed or leveled with Chemqua Prime in order to achieve an even surface. Allow the primer to cure for 36 hours. After this,s depending on the system selected, apply suitable products over it from Chemsol’s wide product portfolio.

Mixing

Stir the resin part mechanically. Add hardener to this mixture as per the prescribed ratio and stir continuously for 2 minutes until a homogeneous mass is obtained. Note: that the mixture has a stipulated pot life, hence the laying should immediately commence after mixing the contents.

Cleaning of Tools

Clean all tools and application equipment with water immediately after use. Hardened and/or cured material can only be removed mechanically.

Packing

Chemqua prime Resin and Hardener is available in 20 liter and 5-liter plastic nails

Storage Conditions

Store in dry and covered shed between 5°C to 30°C, away from sources of heat and naked flame.

Handling & Safety

Keep the containers tightly sealed when not in use. Avoid skin contact and inhalation of fumes (if any). While spraying, it is advised to wear a mask. If it comes in contact with the body, wash affected parts with plenty of soap and water. In case of persistent irritation, contact a physician
