Silicone Masonry Water Repellent

About Silicone Masonry Water Repellent

CONSTRUCTION CHEMICALS Masonry  Silicone Water Repellant Compounds PMS40

 DESCRIPTION

PMS40 is a water dilutable alkali-alkyl siliconate used to protect building material from destruction by water without significantly reducing water vapour permeability. PMS40 develops its water repellent properties by reaction with atmospheric carbon dioxide (CO2). The active substance formed from the silicone water repellent is polymethylsilica. It also provides a barrier against rising damp. PMS40 reduces the phenomenon of efflorescence caused by the presence of soluble salts in bricks.

GENERAL CHARACTERISTICS

Appearance :

Clear to Pale Odour : Characteristic Diluent : Water Potassium methyl siliconate content % : 42 Specific gravity @ 25C : 1.30

APPLICATIONS

Imparting water repellency to: Low fired clay products immediately after manufacturing: e.g., facing bricks, floor tiles, and flower pots. Aerated concrete, plastered surface., Gypsum and gypsum based plaster-boards. Light fillers, such as perilite and aerated concrete granules. Insulating materials. Also: Can be added as an additive for clays, ceramics, and latex paints. Can be mixed with sodium silicate paints for use as a binder in pigments paints. Can be injected into buildings as grouting, just above ground level to form a damp course.

SPECIAL FEATURES

Good penetration depth. Tack free, durable finish. Does not seal the pores and capillaries and allows the surface to remain breathable and penetrable. No change in the appearance of the treated surface. The treated surface does not become glossy Increases the life span of the substrate by reduction in water absorption and therefore reduction in spalling due to freeze-thaw and efflorescence. Water based and environment compatible. Colourless and non-yellowing

Reliable Masonry Protection

This water repellent provides robust defense for exterior masonry surfaces against moisture, rain, and environmental damage. With the ability to deeply penetrate and form water-resistant beads, it offers durable, long-term protection with minimal maintenance required.


Effortless Application and Coverage

The silicone-based emulsion can be brushed, rolled, or sprayed onto clean, dry surfaces, making it suitable for professionals and DIY enthusiasts alike. Each liter covers approximately 68 square meters depending on surface porosity, ensuring efficient use of material.


Environmentally Conscious and Safe

Formulated with low VOC content and non-toxic ingredients, this product ensures user safety and minimal environmental impact. It meets industry standards, is stable through multiple freeze-thaw cycles, and has a long shelf life when stored properly.
