Brand Fosroc, Color Red Brushbond Waterproofing Chemical, UsageApplication water bruising

Main uses suitable for sealing water tanks, Reserviors, Toilets and bathrooms, Balconies and basements together with filling blowholes, Cracks, Imperfections and for providing concrete surfaces with a uniform appearance. Advantages minimum surface preparation needed excellent adhension. Bonds directly to porous and non, Porous surfaces waterproof and non, Toxic, Ideal intended for safe water consumption tanks excellent for damp, Proofing basements below ground breathable, Allows transmission of water vapour from interior of building high resistance to carbon dioxide and chloride ion diffusion can fill dot surfaces, The honeycomds and concrete with potholes application instructionspreparationall the surfaces which are to must be, Receive brushbond free from oil, Grease, Wax, Dirt or various additional options form of foreign matter which might affect adhesion. Spalled and deeply disintergrated concrete should be removed to sound concrete and repaired with renderoc system. Mixingbrushbond liquid is poured into a plastic or metal drum. To this, An equal volume of clean fresh water for brush, Is added application consistency. Then mixing is started with a slow speed drill 350, 450 rpm . The powder component is added gradually to the liquid avoiding lump formation and mixed for 2, 4 minutes. Mix and use. More material must not be mixed than is applicable for within pot life. Retempering with water should not be done. Keep on stirring during application. Applicationfor best results moisten the surface before coating with brushbond. Apply the mixed material using a short, Stiff bristle brush preferably 100 to 150mm width like a paint. Trowel applications can be undertaken as necessary using the correct mixing ratio to obtain satisfactory consistency. Brushbond shall be applied in two coats to achieve 1mm thickness. The additional layer of brushbond shall applied as soon as the fi rst coat has reached touch dry state. On hot substrates, I. E., Over 400c surface temperature, A primer coat of mixed brushbond powder and water with a slurry like consistency should be applied. Prime only areas that may serve as coated with brushbond powder before the primer dries. Material should not be applied at temperatures below 100c. It is recommended that for general re, Surfacing the total depth of the applied material be 1 to 2 mm. Areas subjected to moderate and heavy loads/hydrostatic pressure, Minimum 2mm thickness coating is recommended with screed above. Allow the brushbond to allow drying prior to covering with screed. Sprinkle coarse sand on wet surface of final coat for better adhesion of screed. Average drying time is 4 to 6 hours at normal temperatures. Water curing or curing membrane shall not be applied over only air, Brushbond coating curing is recommended. Mechanical key vertical & horizontal application sprinkle sieved coarse sand on wet surface of final coating for better adhesion of plaster or screed. Allow the coating for drying purposes a minimum period of 7 days before covering with apply a coating to the vertical surface & 3 days before covering with screed/ plaster on the horizontal surface. Maximum thickness of cement plaster recommended is 12 to18mm & height of 1mt in one unit day to avoid de, Bonding of plaster from brushbond coating. Any deviation from the above recommendation please contact local fosroc offi ce for advice. Subsequent finishesbrushbond provides an aesthetically pleasing surface fi nish texture based on the method and does, Of application not normally require any further surface fi nishes. Brushbond is however compatible with most forms of subsequent coatings. Cleaningbrushbond should be taken away from tools and equipment immediately after use with clean water. Hardened material canbe removed mechanically.
