Product Description
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.

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 ProtectionThis 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 CoverageThe 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 SafeFormulated 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.
FAQs of Silicone Masonry Water Repellent:
Q: How should the Silicone Masonry Water Repellent be applied?
A: For optimal results, ensure the surface is clean, dry, and free from dust and oil. Apply the emulsion using a brush, roller, or spray. Allow 2-4 hours for drying, with full water repellency performance achieved after 24 hours.
Q: What benefits does this water repellent offer over conventional sealers?
A: This product penetrates deeply and creates a durable, water-beading protective barrier while maintaining the natural appearance of masonry surfaces. It is low in VOCs, non-toxic, and environmentally friendly, making it a safe choice for residential and commercial projects.
Q: Where can I use the Silicone Masonry Water Repellent?
A: It is suitable for a variety of masonry surfaces including concrete, brick, and natural stone, typically used on exterior walls for water protection in construction or renovation projects.
Q: What is the recommended coverage for this water repellent?
A: One liter covers between 6 and 8 square meters depending on the porosity and texture of the substrate. For highly absorbent surfaces, coverage may be slightly reduced.
Q: How long does it take to fully cure after application?
A: While the treated area dries to the touch in 2 to 4 hours, full water repellent performance develops after 24 hours of curing.
Q: What is the shelf life and how should the product be stored?
A: The product has a shelf life of 12 months when stored in its original, tightly sealed HDPE container in a cool, dry place.
Q: What makes this product environmentally friendly and safe to use?
A: Its low VOC formulation, non-toxic and odorless nature, and compliance with construction chemical standards ensure it is safe for use and has minimal impact on the environment.
