Perma Treat –WB is a water based silicon water repellent. Perma Treat-WB can be diluted with water in various proportions before application. Perma treat-WB treated surfaces retain the original finish to make the surface water repellent and at the same time do not hinder the breathing property of cementitious surface. Perma Treat-WB treated surfaces do not show the signs of ageing. Perma treat-WB allows the cementitious surface to breathe normally. Perma Treat-WB is used for injection grouting to arrest rising dampness. It is found to be an excellent admixture in the manufacture of bricks and blocks.
DIRECTIONS FOR USE
A. SURFACE APPLICATION:
Dilute Perma Treat-WB with soft potable water and brush or spray apply on the dry vertical or inclined surfaces. However spray application is preferred for better penetration of the surface. While spray applying concentration of spray should be kept such that at least 300 mm of drip flow is seen. Dilution rate and coverage on various surfaces are as follows. Note: if the water available is hard then procure soft water or soften the hard water with EDTA (Sodium Salt of Ethylene diamine Tetra Acitic Acid). A pinch of the chemical in a bucket of hard water will make it soft. Treated surfaces develop water repellency only after 72 hours in hot weather.
|Type Of Surface||Dilution Perma Treat-WB: water||Coverage/Ltr. of Treat-WB|
|Un Painted Plastered Surface||1:15||500 sq.ft.|
|Concrete Surface||1:10||1000 sq.ft.|
|Painted Surface||1:10||1000 sq.ft|
|Clay Tiles||1:10||1000 sq.ft.|
|Brick or Block work||1:20||1000 sq.ft|
B. INJECTION GROUTING FOR DPC:
For creating damp proof course to arrest the rising dampness, expose all the bricks by removing the skirting tiles and plaster from the wall at floor slab level. Drill holes in each brick to a depth, which is equal to half of the thickness of the brick wall and fix nozzles. Dilute Perma Treat WB with water in the ratio of 1:15 and inject into each hole till sweat is observed on the surface. After all the holes are grouted plug all holes. Replaster the surface after one week with cement sand mortar admixed with Perma Treat WB diluted with water 1:10 at a dosage of 5 litre per 50kg bag of cement.
Considering a 4″ thick wall volume of one course of brick per running meter is 7000 cc.Porosity in this one running meter is 30% or 2100 cc . This requires roughly about 132 cc of Perma Treat per running meter of the wall. Hence the cost of material will be about Rs.40/-RM or Rs.12.5 /- R feet.
C. AS AN ADMIXTURE:
In making bricks, blocks, clay tiles, mosaic tiles etc. dilute Perma Treat WB with water in the proportion of 1:50 and replace 50% of gauging water with this diluted Perma Treat -WB.
D. DIP TREATMENT:
For reducing the absorbancy of clay tiles, cement tiles, mosaic tiles etc immerse them in a bath containing Perma Treat – WB diluted in the proportion of 1:100.
