Method of Application

All Chemsol Products are recommended to be applied only by Approved Applicators and should be used after using proper PPE’s like Gloves, mask, goggles etc.

Substrate Quality

The CDS (clean, dry, sound) test must be conducted before application of primer to the concrete substrate. The substrate must be free of all contaminants such as dirt, oil, grease, coatings, and surface treatments, etc. If in doubt, apply a test area first.

Application conditions

*Note: The substrate temperature must be at least 30C above the prevalent dew point temperature to reduce chances of condensation on the floor.

Application of floorchem BC

*Ensure that the underlying coat is thoroughly cured and is dust-free. Stir the resin part mechanically for 1 minute, then add the hardener and continue stirring for a further 1minutes. Now add the aggregates and continue stirring for 2 minutes with a motorised helical paint stirrer until a uniform mix has been obtained. Pour the material on the floor and spreadit with a notch trowel to obtain the desired thickness. Now broadcast the sand to excess on it till the material is still tacky.

Curing Schedule

Refer the following table to know how quickly the floor can be brought to service

Temp (°C)	Foot Traffic	Full Cure
10°C	48 hours	120 hours
20°C	36 hours	72 hours
30°C	24 hours	72 hours

Cleaning of Tools

Clean all tools and application equipment with thinner PT 36 immediately after use. Hardened and/or cured material can only be removed mechanically.

Packing

Floorchem BC is available in pre weighed kit of 30 kg.

Handling and 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.
