Brushbond
A cr y lic pol y mer modified elas tomeric waterproofing membrane coating for concrete and masonry surfaces
Uses Brushbond provides a seamless, waterproof coating suitable for use in water tanks, reservoirs, swimming pools, roofs and to ensure water tightness. Brushbond effectively protects against concrete decay providing a long lasting barrier to waterborne corrosive salts and atmospheric gases.Brushbond is designed to re-face and even out variations in concrete and masonry surfaces.Brushbond effectively seals concrete masonry walls and bridges the shrinkage cracks which are static. Brushbond provides a tough and durable coating which cannot be easily damaged or worn away. Advantages  Minimum surface preparation needed - Low labour costs.  Applied directly to the damp concrete and masonry  Excellent adhesion - Bonds to porous and nonporous surfaces.  Non-toxic-ideal for potable water tanks  Waterproof - Excellent for damp-proofing basements  Breathable-allows transmission of water vapour from interior of building  Excellent for concrete roof, leaking brick walls and masonry

Brushbond provides an elastomeric protective waterproof coating and is shown to resist positive hydrostatic pressure upto 7 meter head. The degree of resistance of Brushbond to water under pressure depends on the coating thickness. Areas subjected to moderate and heavy loads/hydrostatic pressure, minimum 2mm thickness coating is recommended with screed above.

Application Instructions

All the surfaces which are to receive Brushbond, must be free from oil, grease, wax, dirt or any other form of foreign matter which might affect adhesion. Spalled and deeply disintergrated concrete should be removed to sound concrete and repaired with Renderoc System. Mixing Brushbond liquid is poured into a plastic or metal drum. To this, an equal volume of clean fresh water is added, for brush 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 should not be mixed than can be used within pot life. Retempering with water should not be done. Keep on stirring during application.

 Good resistance to Carbon dioxide and Chloride ion diffusion Description Brushbond is a two component acrylic polymer modified elastomeric waterproofing membrane which consists of Brushbond powder and Brushbond liquid acrylic emulsion. It requires only the addition of water on site and when mixed in the proper proportions, an easily brushable coating is produced. Brushbond can simply be applied by a stiff brush, or trowel to obtain the desired thickness.Brushbond consists of specially selected cements, graded hard-wearing aggregates and additives supplied in powder and Brushbond liquid component of blended acrylic copolymers. The polymer provides Brushbond with exceptional adhesion, toughness and durability.

Application Technical Support The company provides a technical advisory service supported by a team of specialists in the field. Properties
Brushbond

For 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 second coat of Brushbond shall applied as

Brushbond
soon as the first coat has reached touch dry state. On hot substrates, i.e., over 40 0C surface temperature, a primer coat of mixed Brushbond and water with a slurry like consistency should be applied. Prime only areas that can be coated with Brushbond before the primer dries. Material should not be applied at temperatures below 10 0C. It is recommended that for general re-surfacing the total thickness 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 dry before 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. Subsequent Finishes Brushbond provides an aesthetically pleasing surface finish texture depending on the method of application, and does not normally require any further surface finishes. Brushbond is however compatible with most forms of subsequent coatings. Cleaning Health and Safety instructions Brushbond should be removed from tools and equipment immediately after use with clean water. Hardened material can be removed mechanically. Brushbond is non-toxic but it is alkaline in nature. Gloves and goggles should be worn. Any splashes to the skin or eyes should be washed off with clean water. In the event of prolonged irritation, medical advice should be sought. Should use a dust mask while handing the powder. Packaging Brushbond is supplied as a package of 23kg (Industrial Pack) and 6kg powder. Brushbond Liquid is supplied in 4.28kg and 1.05kg jerry can. Coverage This depends on the required consistency. The approximate coverage per pack at even consistency (1 mm thickness) is as follows : Consistency Coverage in m2 (23kg + 4.28kg pack) Coverage in m2 (6kg + 1.05kg pack) Brush Application 16 - 18 4 - 4.5

Allowances should be made for any possible wastages when estimating. Storage Brushbond has a shelf life of 12 months in unopened packs, if kept in a dry store. In high humidity locations, the shelf life may be reduced to less than 6 months. Prevent Brushbond liquid from freezing. Precautions
