Application Information
Instructions for use

Surface Preparation

All surfaces should be clean, sound and uncontaminated.

This preparation should leave an exposed concrete, free from dust, loose particles, deleterious matter, oil, grease, chemical films and other contaminants.

Pre-Application

Test a small area of the surface (generally 1.0m x 1.0m section) before starting application of the sealer to ensure desired performance results, aesthetics & coverage rate. Allow 5-7 days for the product to fully react.

Application

IDROSIL L is a single component, applied at full strength and never diluted.
Mix the material thoroughly before & during application. IDROSIL L should be applied with a brush, roller or low pressure non-atomizing spray uniformly onto the surface at a rate of 6-8m2/ liter.

For vertical surfaces, flood the surface by applying from the bottom up applied to saturation with a controlled (20cm) material rundown to ensure maximum penetration on the surface.

Extremely porous substrate may require two coats. Apply the second coat as soon as the surface of the first coat has been visibly dry which around 2-4 hours at ambient temperature. Cooler temperature or higher relative humidity may extend drying time.

Surfaces with salty efflorescence must be cleaned mechanically or washed with acid cleaner and subsequently rinsed with   water. Wait for the surface to dry, before proceeding with the application of IDROSIL L.

All cement supports must be allowed to cure for at least 21 days before being impregnated with the product.

Cleaning

Equipment and tools used should be cleaned promptly with water.

Recommendations

  • Water based coatings dry by evaporation of water from the film. It is necessary to protect the newly applied material during this time form the rain, freezing conditions, high temperature, high relative humidity and physical damage.
  • Do not apply if rain, dew or water exposure is expected with 24 hours of application. Avoid application in direct sunlight and during high winds.
  • Not recommended for dense surfaces such as tiles or granite.
  • Do not apply in areas where negative hydrostatic pressure is possible.
  • Apply in thin coats only.
