Chembase 150

3-component, self-leveling epoxy-based flooring screed mortar

Product Description

Chembase- 150 is a specially formulated 3-component self-leveling, low viscosity, high gloss, high strength epoxy mortar screed commonly used as an intermediate layer between primer and top coat. It is also recommended for use as a primer coat by using it in an unfilled form.

Uses

For priming concrete substrates, cement screeds, and epoxy mortars.
Used as water-wipeable grout for Kota stones, with the aid of aggregates and colour.
Intermediate layer underneath Chemtop-1000

Method of Application

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

Substrate Quality

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

Application conditions

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

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 levelling 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 levelled with Chemprime/Chembase 150 in order to achieve an even surface. Allow the primer to cure for 5-6 hours. After this, Mix Chembase-150 Resin and Hardener in a ratio of 2:1 and add Aggregate AG80/AG257 in a prescribed ratio and mix for 2 minutes with a helical paint mixer. Visually ensure that the mixture has become homogeneous. Immediately lay the mixture on the floor and spread it with a trowel to the desired thickness. Use a spike roller to deareate the coating.

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

Chembase 150 Resin and Hardener is available in 20-liter and 5-liter plastic pails. Aggregate AG80 and AG257 are available in 50 kg bags.

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.
