  • Coverage Rate: 2 – 25 m2/L depending on surface porosity

Application

The surface to be treated should be clean and free of all contaminants.
The surface can be damp or wet, however SilaSeal should not be applied to a surface that has pools of water. The pools should be removed using a broom or cloth prior to application.
Do not apply SilaSeal if rain is expected within 24 hours of application.
Do not apply if extreme weather conditions are expected.
Do not apply if surface temperatures are above 30degC.
If necessary, cool the surface with water prior to application. SilaSeal is ready to apply and should be mixed well before use. A test prior to application must be performed to assess the suitability of the product. SilaSeal may be applied using a saturated brush, roller, paint pad or a low-pressure hand sprayer. The surface should be impregnated to saturation point in a single application. During application, care should be taken to minimise overlapping of treated areas that have already dried. If overlapping of dried, treated areas has occurred the sealer should be wiped from the surface before drying to reduce the risk of white stains. Do not allow pooling of sealer. Pools can be spread out using a soft bristled broom. Excess sealer must be removed before drying. Risk of white stains in case of excess. Any overspray on adjacent surfaces such as glass, metal or painted surfaces should be wiped clean with a damp rag before the sealer dries.

Full curing may take up to 7 days.
Avoid traffic for at least 24 hours. Equipment clean up can be performed with water.
