Sika® RainTite I

Acrylic based multipurpose polymer for repair and waterproofing

Sika® RainTite I is a multifunctional polymer emulsion for enhancing the properties of mortar/concrete/grout/cement slurry. It provides a good adhesion, water resistance and improvement of several other properties.

  • Improved impermeability against water ingress   
  • Extremely good bonding to moist substrates, extremely improved mechanical, flexural strength and abrasion resistance properties
  • UV resistant & suitable for external coating
  • When used as an additive to cement based paint improves impermeability, water repellence and anti fungal property of the painted surface (site trials are always advised before application for shade variations, if any)
  • Sika® RainTite I can be diluted with water (1 : Nil to 1 : 4) depending on the type of application
  • Screed required with Sikacim®/ Sika® Plastocrete Super to protect waterproofing layer

Application steps

SUBSTRATE PREPARATION

Substrate must be clean, dry, homogeneous, free from oils &grease, dust & loose or friable particles, paint, cement laitance, old coatings and any other contaminants. Also remember the cementitious substrates should be pre-saturated surface dry with clean water.

MIXING

Refer to the table above of Mixing ratio and always add powder to liquid for all applications.

APPLICATION

Concrete, mortar, slurry should be prepared by using Sika® RainTite I enriched water and to be applied with in 20-30 minutes of preparation. In case of bond coat subsequent mortar or concrete to be applied when bond coat is fresh & tacky.

Screed required with Sikacim®/ Sika® Plastocrete Super to protect waterproofing layer.

Standard coating system can be further reinforced by placing Sika® Fab1 fabric layer in between 1st and the 2nd coat.

When Sika® RainTite I is used as an additive to cement based paints it is recommended that the same should be done for preferably light shades only. However, pre-test for consistency of colour shade is recommended through site trials before application.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with clean water immediately after use. Hardened /cured material can only be removed mechanically.
