Chemilink™ SS-251

Flexible Cementitious Waterproofing Coating

Chemilink™ SS-251 is a two-component flexible cementitious waterproofing membrane system based on special synthetic resin dispersion and a blend of selected cement mixed with well-graded fillers. Chemilink™ SS-251 is flexible and adheres to practically every surface. It can also fill hairline cracks with excellent functions of waterproofing, wear-resisting and weather-resistant.

  • Waterproof coatings of tanks, containers, water reservoirs, pools, silos and gutters;
  • Kitchen and toilets; Balconies and planter boxes; Basement walls and lift pits
  • Waterproofing and repair of balconies, terraces and haunching concrete of roads and bridges;
  • Floors in garages, on parking areas and on roofs; and
  • Under surface and side of marbles, tiles and granite.

Application Procedure

  1. The substrates must be clean and sound, free of dust and loose particles. All substrates must be pre-saturated with water to achieve saturate-surface-dry prior to application of Chemilink™ SS-251.
  2. Pour Chemilink™ SS-251B (Part B, liquid) into a clean container and stir/mix with a low speed drill. Pour Chemilink™ SS-251A (Part A. powder) slowly into Part B taking care to mix thoroughly until homogenous and lump free.
  3. A squeegee, roller or broad brush may be used to apply the slurry. The recommended thickness for each coat is approximately 0.5mm dft. To ensure permanent protection, a second or even third coat is necessary.
  4. Normal concreting procedures should be strictly adhered to.
  5. Application temperature: 5ºC ~35ºC
