Small round panes of water glass were first industrially manufactured for used as windows in the 19th century by Van Baerle in Gernsheim and Johann Gottfried Dingler in Augsburg. Sand mixed with potash and heat coalesced into pearls of water glass. The city hall in Schwyz and "Gasthaus Weißer Adler" in Stein am Rhein (both in Switzerland) received their coats of mineral paint in 1891, and facades in Oslo from 1895 or in Traunstein, Germany from 1891.Īlchemists in their pursuit of the philosopher's stone (to manufacture gold) found glassy shimmering pearls in fireplaces. Lifetimes exceeding a hundred years are possible. Mineral silicate paint coats are considered durable and weather resistant. They are also called water glass paints or Keimfarben (after the inventor). These paints use potassium water glass as binder. Mineral colors are commonly understood to be silicate paints. Lime paints (aside of Fresco-technique) are only moderately weather resistant, so people apply them primarily in monument preservation. Together they form calcium silicate hydrates. Under influence of carbon dioxide, lime-based binders carbonate and water silicate-based binders solidify. Two relevant mineral binders play a role in the field of colors: Lime and silicate. Remove them directly after application of finish.Īpply ProRend WRM in 2 coats with a block brush, roller or spray equipment, allowing WRM to dry between coats.Silicate mineral paints or mineral colors are paint coats with mineral binding agents. Do not apply WRM on surfaces that have already been painted.Ĭover parts which do not have to be treated with ProRend WRM with paper and tape. Treat powdering or porous backgrounds with ProRend Deep Primer. ProRend WRM can be applied to mineral backgrounds, ProRend Basecoats and decorative renders. Water Repellent Masonry Paint (WRM) General Information Packaging Refer to material safety data sheet for full details of safety measures Dilute first coat with 10% water, second coat with 2% water Remove them directly after application of finish.Īpply ProRend SCM in 2 coats with a block brush, roller or spray equipment, allowing ProRend SCM to dry between coats. Protect fresh render work against weather influences.Ĭover parts which do not have to be treated with ProRend SCM with paper and tape. The background has to be supporting and free from dust, loose particles, damp and other pollution which can be of disadvantage to the bonding. Do not apply ProRend SCM on surfaces that have already been painted. ProRend SCM can be applied to mineral backgrounds, ProRend Basecoats and decorative renders. If the coating must be applied in adverse weather conditions, it is essential to protect both the working area and finish before and after application. ProRend SCM must not be applied to frozen or thawing substrates. Temperature range, 5 - 30 degrees centigrade. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified. Scaffolding must be independently tied, to allow uninterrupted application. Self-Clean Masonry Paint (SCM) General Information PackagingĬan be kept for 2 years in cool dry conditions and off of the ground.ĭesign, preparation and application of external rendering and internal plastering should be followed at all times. ProRend SCM is non-filming and thermoplastic. ProRend SCM has excellent adhesion, coating capacity, is hydrophobic, impervious to torrential rain and algae resistant. ProRend SCM is self-cleaning, scratch, scrub and chip proof, highly vapour permeable, tension free and requires little maintenance. Silicone paint has excellent adhesion, coating capacity, is water repellent, impervious to torrential rain and algae resistant. ProRend WRM is scratch, scrub and chip proof, highly vapour permeable, tension free and requires little maintenance. High-quality, synthetic wall paint on silicone resin base. ProRend Self-Clean Masonry Paint (SCM) is a hydrophobic, self-cleaning exterior paint used for application over mineral backgrounds, ProRend basecoats and decorative renders. ProRend Water Repellent Masonry Paint (WRM) is a silicone based exterior paint used for application over mineral backgrounds, ProRend basecoats and decorative renders.
