Ressi SLS Primer 1
Ressi SLS Primer 1 is a specialized primer formulated to improve substrate preparation and enhance bonding performance for flooring and coating systems. The product penetrates effectively into concrete and cement-based surfaces to create a stable bonding layer for improved application durability. Its reliable formulation supports surface strengthening and helps reduce substrate-related coating issues in demanding industrial and commercial environments. Ressi SLS Primer 1 is suitable for floor preparation, protective coating systems, and maintenance applications where strong adhesion and long-term performance are required.
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.
