Method of Application

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

Application conditions

*Note: The substrate temperature must be at least 3 °( above the prevalent dew point temperature to reduce chances of condensation on the floor.

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, and surface treatments etc. If required, apply a test area first.

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 ar expose surface defects such as blowholes ar voids. Repairs to the substrate, filling c blowholes/voids, and surface levelling must be carried out using appropriate products. Ensure that the dust, loose and friable material completely removed from all surfaces by brush or vacuum before application of the product.

The concrete substrate has to be primed or levelled with Chemprime in order to achieve an even surface. Allow the primer to cure for 5-6 hours. After this, depending on the system selected either apply a screed coat followed by a top coat

Mixing

Stir the resin part mechanically. Add colour paste into resin and mix till a uniform colour is achieved. Add hardener to this mixture and stir continuously for 2 minutes until a homogeneous mass is obtained. Add aggregates to this mixture and continue stirring for a further 3 minutes with a motorised helical paint stirrer until a uniform mix has been obtained. Overmixing must be avoided to minimise air entrainment.

*Note that the mixture has a stipulated pot life, hence the laying should immediately commence after mixing the contents.

Curing Schedule

The epoxy curing reaction rate is temperature dependent. Refer to 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	96 hours
30°C	24 hours	72 hours

Cleaning of Tools

Clean all tools and application equipment with thinner EP140 immediately after use. Hardened and/or cured material can only be removed mechanically.

Packing

Chemtop EPU Resin, Hardener, and aggregates are available in a 16.4 kg pre-weighed kit

Storage Conditions

Store in a 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 water. In case of persistent irritation, contact a physician.
