Supreme Silicone's Water Repellent Exterior Coat AQUAREST WR 1100 is a solvent less, water- soluble, Silane Siloxane Emulsion. Dilute solutions of WR 1100 serve as general-purpose water repellents for impregnating and priming mineral surfaces. As water-repellent primer for emulsion paints and plasters, silicone resin, Emulsion paints and silicone resin plasters, as well as for concrete coatings.

Typical Values – Should not be considered as specifications.


• Excellent penetration in absorbent mineral building materials.
• Very good alkali resistance.
• Fast curing hence imparts water repellence soon.
• Neutral in nature, no color change to the substrate.
• Provides excellent water repellency.
• Easily dilutable by Tap Water.
• The pores and capillaries are not sealed and hence maintain breath ability while preventing water absorption.
• The coatings are UV stable and resistant to biological degradation.
• Provides good adhesion for paints.
• Water-based and environmentally compatible.


WR 1100 emulsion contains a stabilized mixture of silane and Siloxane that are susceptible to hydrolysis. Hydrolysis occurs only after application to the substrate, which breaks the emulsion. Alcohol is released and the emulsion is converted into a silicone resin water repellent. It reduces the capillary absorption of the building which it has penetrated, but does not clog pore or capillaries. There is therefore little or no impairment of the building material's ability to "breathe".
WR 1100 is diluted with Water. We recommend the dilution ratio of 1: 5 to 1: 12), the exact figure depending on how absorbent the substrate is. For adequate penetration on very high quality concrete, it may be necessary to dilute only 1: 2. Apply the solution in the usual way; flooding is the preferred way. Two "wet on wet" coats are needed to ensure complete coverage.


When stored bellow 35°C away from direct Sun Light in the original unopened containers, WR 1100 has a usable life of 6 months from the date of manufacturing.
