Ressi SLS Primer 1

Primer for Self-Levelling Screeds

Ressi SLS Primer 1 is a latex based primer to be used over concrete and cementitious surfaces prior to the application of self-levelling screeding materials such as Ressi SLS 610. It forms a tacky film over cementitious floor surfaces which aids in better binding of the screed over the substrate.

Ressi SLS Primer 1 is free from solvents, plasticizers and ammonia. It can also be used as an additive in self-levelling screed materials if further crack reduction and flexibility are required.

ADVANTAGES

Reduces shrinkage in the mix
Improves adhesion of self-levelling screed over cementitious surfaces
Suitable for both internal and external applications
Non-toxic
Easy to apply
Enhanced usability – Can be used as a primer, shrinkage reducer for mortars and crack fillers

APPLICATION

Ensure the concrete / cementitious surface is clean and free from dust, oil or any material which would hinder adhesion. The product may be further diluted with water depending on substrate condition and absorption.

Ensure thorough coverage. Prior to application of self-levelling screed, the primer must be tacky to touch. If dry, apply another coat. Screed application must be done while primer remains tacky (not fully dry).

COVERAGE

As a neat bonding agent: 5–7 m² / Ltr / Coat. Actual coverage depends on texture and porosity of substrate.

As an additive for tile adhesives, bedding mortars, sand-cement renders, plasters and screeds: dosage may vary from 10–20% by weight of cement. Follow recommended mix design for optimum results.
