Chemilink™ SS-222 Normal Setting

Cement-Based Self-Leveling Compound

Chemilink™ SS-222 is a grey powder mix of special cements, synthetic materials with a good dispersing effect and well chosen filling materials. This material requires only the addition of water to produce a smooth free-flowing and self-leveling mix. It is designed to provide surfaces with a thickness of 3mm to 10mm. The mortar hardens by hydration and drying into a stress free compound. The development of cracks virtually be excluded. Chemilink™ SS-222 is the result of extensive research, development and commercial trials and is manufactured under strict quality control.

Functions

Leveling of concrete floors and ceilings, cement screeds, anhydride screeds, tiles and slabs in thick layers;
For all areas, prior to laying of floor coverings; as wearing surface in basements, lobby and playrooms, corridors, attics, storage rooms, halls and workshops, with moderate impact stress.

Benefits

Easy application due to easy gauging with water.
Economical due to quick easy laying and rapid hardening.
High bonding and compressive strength.
Can be used directly on concrete floor to provide smooth surface.

Application Procedure

Surface Preparation

The substrate should be solid with certain roughness, clean and free from dust, grease and loose materials. On dry absorbent surface, the surface should be moistened if necessary. For better results, Chemilink™ SS-232 (20% or 35%) Liquid Bonding Agent is applied as two coating layers at an hardened, it is recommended to put another coat on the interval 2 hrs for surface preparation. After it had surface to provide resistant to shrinkage.

Mixing

Mixing e.g. 25kg of Chemilink™ SS-222 powder with approximately 20 - 25% by water or 5.5 – 6.5 litres of water. Mechanical mixing is recommended. Mixing must go on for 3 – 7 minutes depending on the speed of the mixing equipment.

Placing

Chemilink™ SS-222 should be placed within 30 minutes after mixing. Use only a fresh mix after that time. The mortar can easily be spread and applied with a spacer equipped trowel.

Curing

In hot and dry conditions Chemilink™ SS-222 should be cured with water spraying or appropriate curing compound.
