Chemqua1000 SL

4-component, self-leveling, water-thinnable epoxy system

Product Description

Chemqua1000 SL is a specially formulated 4-component self-leveling, odour-free, VOC-free water-based epoxy system.

Uses

New concrete slabs with high humidity
Concrete floors with moisture-related issues
It can also be used as a sealer coat for dust-proofing applications.
slabs without a damp-proof membrane and a risk of rising moisture
Places where chemical odour occurs during application are unacceptable.

Salient Features

12months from the date of manufacturing if stored properly in undamaged seal packaging, at a temperature between 5°C-30°C.
It should be kept in a cool, well-ventilated area, away from heat, direct sunlight, sparks and children.

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

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 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 Chemqua Prime 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 of Chemqua ECS, followed by a top coat of CHEMQUA 1000S, L, or the topcoat of CHEMQUA 1000SL can also be directly applied to the primer 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	12 Days
20°C	36 hours	8 Days
30°C	24 hours	6 Days

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 1000 SL Resin, Hardener, and aggregates are available in pre pre-weighed kit which covers 10-12 sq m area with an approximate thickness of 1mm.

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 soap and water. In case of persistent irritation, contact a physician.
