Chemilink™ SS-235

One-Part Polymer Modified Repair Mortar for Concrete

Chemilink™ SS-235 is a one-part cementitious, pre-packed, pre-weighed polymer modified cementitious repair mortar used for patching, repairing, filling and leveling of reinforced concrete or any cementitious surfaces. Chemilink™ SS-235 mixed with water to form a high strength, cohesive and durable or water resistant mortar. It is a quality controlled high performance composition which will achieve high compressive strength characteristics. The presence of a copolymer ensures an excellent bond to most surfaces and enhances such properties as impermeability, flexural and tensile strengths.

Setting Time: Initial Final	4 hours 8 hours

Applications

As a patching mortar for stalling concrete, worn out surface of wall renderings or floor screeding;
It can also be used as a thin-set bedding material for bedding ceramic tiles and all natural or manmade stone;
For repair of honey combed concrete, after the formwork have been removed; and
Use as a crack filler and also as a general mortar for thin-bed or thick-bed tile adhesive installation.

Application Procedure

Surface Preparation

The substrates must be clean and sound, free of dust and loose particles. Surface must be primed with Chemilink™ SS-232 to achieve maximum results prior to patching.

Mixing

A powered paddle mixer is recommended for mixing. Mixing should be carried out by adding the Chemilink™ SS-235 powder to 3 to 3.5 litres of water in the mixer (with the mixer running) and mixing for approximately 3 minutes, or until a smooth homogeneous grout is produced.

Application Procedure

Apply Chemilink™ SS-235 with a trowel and press hard. Build up to the maximum thickness in a series or thin layers, applying the next layer once the preceding layer has stiffened, but not set. The thickness of the Chemilink™ SS-235 layer in a single application should not exceed: 40 mm vertically; 35 mm overhead.
