Waterproofing Coating Fosroc Brushbond Tgp, Packaging Size: 15 kg

Product Details

Brushbond TGP* crystalline waterproofi ng system is used for waterproofi ng against the positive or negative sides of hydrostatic heads of water, for dampproofi ng, repairing cracks, plugging holes, sealing wall - fl oor joints and stopping active leaks in a wide variety of condtions including : ??? Sewage treatment and water treatment plants, tanks, foundations, tunnels and manholes. ??? Terrace garden, balconies, sunshades etc. ??? Roof and Sunken slabs ??? Industrial and offi ce buildings ??? Reservoirs, water holding structures etc. Advantages ??? Meets the requirements as per ANSI/NSF Std 61 for suitability to potable water ??? Penetrates concrete, seals capillary tracts ??? Contains no chloride ??? Easy to apply ??? Resists chemical attack of sewage and industrial wastes ??? Suitable for external and internal applications. Description Brushbond TGP* crystalline capillary waterproofi ng system contains proprietary blend of portland cement, quartz aggregate and special chemicals. In the presence of moisture, the active chemicals in Brushbond TGP* crystalline waterproofi ng system penetrates concrete and react chemically with free lime to produce insoluble crystals. This crystalline growth reduces porosity by blocking capillaries and fi lling hairline non structural cracks ( upto 0.25mm wide) caused by shrinkage or expansion. Unlike metallic and membrane types of waterproofi ng which only form a surface barrier, Brushbond TGP* crystalline waterproofi ng system, in the presence of water, continues producing crystals and lasting imperviousness to water. Technical support The company provides a technical advisory service supported by a team of specialists in the fi eld. Properties Specifi c gravity : 1.6 to 2.0 g/cc Pot life : 40 minutes Brushbond TGP Instructions for use Surface preparation Old concrete Surfaces must be clean and sound. Remove all oil, dirt, laitance and other contaminants by water blasting. Water blasting is preferred for surface preparation because it mechanically cleans and roughens the surface, is environmentally safer and leaves the surface saturated with water. Surface must be damp for application of Brushbond TGP* crystalline waterproofi ng system, concentrate. New concrete After forms are stripped, acid etch or sand blast / water blast to facilitate penetration of crystals formed during the chemical reaction. Surface must be left damp for application on Brushbond TGP* crystalline waterproofi ng system. Construction joints, cold joints and non-leaking joints greater than 0.25mm wide must be cut in V-groove shape and fi lled with Brushbond TGP* crystalline waterproofi ng system in mortar consistency. Mixing For best results, clean, potable water should be added to Brushbond TGP* crystalline waterproofi ng system concentrate. Application Existing concrete 3 parts of powder shall be added to 1 part of clean and mixed thoroughly with a slow speed drill equipped with a paddle. For larger batches, mixing shall be done with a mortar mixer. Do not mix more material than can be used in 20 minutes @ 270C, 50% R.H. If mixture thickens, it shall be restirred to reduce consistency. Extra water should not be added. Curing and Protecting Brushbond TGP* crystalline waterproofi ng system application must be kept moist for a minimum of 48 hours. After initial set, moist curing, using continuous water spray is recommended. Treated surfaces shall be fog sprayed 3 to 4 times daily for the 48 hour period. For warmer climates, more frequent spraying may be required. It is important to keep the Brushbond TGP* crystalline waterproofi ng system moist to allow the crystal formation to occur. The surfaces shall be protected from foot traffi c for 48 hours or heavy traffi c for 7 days.
