ULTRA BRUSH BIND

ULTRA BRUSH BIND is a high performance elastomeric cementitious coating used for waterproofing and to protect atmospherically exposed reinforced concrete structures from attack by acid gases, chloride ions, oxygen & water. ULTRA BRUSH BIND is suitable for all types of structures including those in coastal environments. The product can be used on concrete, brick and blockwork substrates and is equally suitable for new and existing structures. The product is designed to reface and even out variations in concrete and masonry surfaces and bridge shrinkage cracks. It provides a seamless, flexible waterproof coating.

Advantages & Uses

  Excellent barrier to carbon dioxide, chloride and sulphateions. Internal and external surfaces of underground masonry and reinforced concrete structures (up to amaximum of 1.5 bar of pressure)

  • Allows water vapour to escape from the structure.
  • Waterproof-suitable for water retaining structures.
  • High resistance to the effect of long-term weathering, durable in all climate conditions including UV attack.
  • Lift wells & ornamental ponds and swimming pools,balconies and small exposed areas for pedestrian
  • Nontoxic – ideal for potable water tanks.
  • Flexible, with thermal expansion similar to concrete.
  • Excellent bond to concrete and masonry.
  • Good crack accommodation capacity.
  • Minimum surface preparation needed and low labour costs.
  • Thanks to its two-component formulation it adheres extremely well to various types of substrate: concrete, cementitious render, bricks and blocks
  • Extremely attractive finish, particularly the whiteversion

Description

  • ULTRRA BRUSH BIND is a two component acrylic polymer modified cementitious coating which consists of ULTRRA BRUSH BIND powder and ULTRRA LQS acrylic emulsion. It requires only the addition of clean water at site to produce an easily brushable coating. ULTRRA BRUSH BIND can simply be applied by stiff brush, roller or trowel to obtain the desired thickness

Description

ULTRA BRUSH BIND is a two component acrylic polymer modified cementitious coating which consists of ULTRA BRUSH BIND powder and ULTRA LQS acrylic emulsion. It requires only the addition of clean water at site to produce an easily brushable coating. ULTRA BRUSH BIND can simply be applied by stiff brush, roller or trowel to obtain the desired thickness

Application Instructions

Surface Preparation All surfaces which are to receive the coating must be free from oil, laitance, grease, wax, dirt or any other form of foreign matter which might affect adhesion. Typically concrete surfaces can be cleaned using high pressure water jet or grit blasting or by proper wire brushing. Spilled surfaces or those containing large blow holes, cracks and other such defects should be repaired using ULTRA CRACKFILL-UCF-400 OR  ULTRA READY MIX PLASTER concrete repair mortars.

Mixing

Mixing Ratio

Preparation of the mortar Pour component ULTRA LQS (liquid) into a suitable clean container and slowly add component ULTRA BRUSH BIND (powder) while stirring with a mixer. Carefully mix ULTRA BRUSH BIND for several minutes; make sure no powder sticks to the sides or bottom of the container. Keep mixing until completely blended. A low-speed mechanical mixer is recommended for this operation to avoid entraining too much air into the mix. Do not mix the product manually.

Application

For best results, surfaces should be damp. In order to obtain the protective properties of ULTRA BRUSH BIND, it is important that the correct rates of application are observed. Use a short stiff brush preferably 120-150mm width and apply the mixed material like paint. The application of ULTRA BRUSH BIND should not be done if the temperature of the substrate is below 100 C. When applying ULTRA BRUSH BIND on hot substrates i.e., over 300C surface temperature, saturate the surface with water. Apply ULTRA BRUSH BIND in 2 coats to achieve 1mm thickness. The second coat of ULTRA BRUSH BIND shall be applied as soon as the first coat has reached touch dry state. It is recommended that for general surfacing ULTRA BRUSH BIND should be applied at a minimum thickness of 1mm. Areas subjected to moderate and heavy loads / hydrostatic pressure, minimum 2mm thickness coating is recommended with screed above. Allow the ULTRA BRUSH BIND coating to dry before covering with screed. Sprinkle coarse sand on wet surface of final coating for better adhesion of screed. Average drying time is 4 to 6 hours at normal temperatures.
