Test have shown that CROMFLOORTM WB2K, when applied over concrete, will withstand a hydrotatic pressure of approximately 210kPa for up to 36 hours.(Negative head of pressure = 20.7m )

Application Guide.


Surface Preparation

  1. Concrete surface should be free from grease and oil - if necessary,clean with industrial grade degreaser of apply a poultice.
  2. Steps must be taken to remove laitance. This is best carried out by using either mechanical abrasion or acid etching. Upon completion of etching, neutralise, rinse thoroughly and allow to dry.
  3. Loose or weak concrete should be removed and the surface repaired by first priming with CROMFLOORTM WB2K, Fill up all voids using a mix of one part of the CROMFLOORTM WB2K mixed to 4 parts of clean fine sand.

Application Procedure and Equipment

  1. Mix Parts 1 and 2 separately first.
  2. Do not mix more product than will be used in 40 minutes as curing will occur. Note Recommended at 25oC and 50% relative humidity. An increase in temperature will reduce the amount of product to be mixed. A decrease in temperature will increase the amount of product that can be mixed.
  3. Mix equal parts of Part 1 and Part 2 together thoroughly. It is strongly suggested to use a high speed drill and propeller mixing blade. Mix for at least 3 - 4 minutes.
  4. Aplly by roller, brush or airless spray.
  5. In cold weather 5% water can be added after Part 1 and Part 2 have been mixed together.
  6. To provide a light profile slip resistant finish add Crommelin Slip Resistant Additive(SRA) to mixed CROMFLOORTM WB2K at the rate to achieve the desired finish(i.e. 100 g/L).
  7. To apply a slip resistant profile adjustable to requirements broadcast dry graded aggregrate into the wet 1st coat and allow to dry. Remove excess aggregate and over coat with 2nd coat.



  1. Do not apply to surfaces that are below 10oC or when relative humidity is above 85%.
  2. Poor mixing or inaccurate mixing ratios will result in variable cure and less than optimum hardness.
  3. Never add more than 10% water.
  4. Do not apply latex adhesives or sealants before CROMFLOORTM WB2K is hard dry.
