A MULTI PURPOSE MORTAR ADDITIVE, ADHESIVE AND CEMENT MODIFIER
Perma Latex AR is a high quality emulsion which enhances the performance of cement, mortar and concrete. Some examples from its innumerable uses are as follows:
- An excellent product in concrete repairs as in combination with cement (1:1) it produces a very strong primer and as an additive in the mortar to make strong waterproof plaster.
- In case of multilayered plaster Perma Latex AR bonding slurry helps in building up layer. The bond coat not only serves as a bonding agent but also as a waterproof barrier.
- Perma Latex AR modified mortar is used in joining prefabricated members and as bedding mortar in precast block work to secure water tight joints.
- In terrace waterproofing and patch up repairs Perma Latex AR forms an important member as it helps bonding new plaster and also helps in making non shrink crack free mortar for repairs.
- Cement Perma Latex AR slurries are used as corrosion inhibitor on exposed reinforcements and on bridge girders to protect them from attack of chlorides and sulphates.
DIRECTIONS FOR USE
1) SURFACE PREPARATION:
Surfaces to receive any repair treatment should be sound, free from loose particles, grease oil or any deleterious material. All loose portions should be cut back to sound concrete. Surface should be sufficiently wetted to saturation level but should be free from stagnant water.
Aggregates should be clean and sound. They should be designed properly with respect to the mix as well as maximum aggregate size with respect to the thickness of concrete or mortar to be laid. In case of mortars maximum grain size of the fine aggregate should be around one fourth the thickness of the member to be cast and it should be graded.
Mortars can be mixed manually or by machine. Dose Perma Latex AR with gauging water. As soon as the mix is ready immediately empty the mixer drum. Do not leave modified mixes in mixer drum after the mixing operation is complete.
4) APPLICATION METHOD:
Application method of Perma Latex AR consists of applying a primer and when the primer is still tacky apply the mortar. Primer is made by mixing Perma Latex AR, water and cement in various proportions. The mortar consists of cement, sand, water and Perma Latex AR in various proportions depending upon the type and area of use.
1) FLOOR REPAIRS:
Prepare the base and apply primer obtained by mixing cement with Perma Latex AR and water in the proportion of (2:1:1). When the primer is still tacky apply mortar which has Latex AR and water in the proportion of (1:6). For repairing the floor duct edges and nosing of stairs let the primer be same but mortar to be added with Latex AR and water in the Proportion of (1:3).
2) WATERPROOF PLASTER:
Mix Latex AR and water in the proportion of (1:6) use this as gauging water in mortar and apply the mortar. Should there be need of primer use (1:4) Latex AR water in cement to form a primer and brush apply this before application of plaster.
3) BONDING OLD CONCRETE TO NEW:
Use Perma Latex AR with cement in the proportion of 1:1 to form a thick slurry. Brush apply this slurry to the old concrete just before concreting.
Curing of the Modified mortar is essential to prevent it from premature drying out. After twenty four hours of application of the mortar start curing or by very light spray for two to three days and then allow it to dry off.
Primer covers 40 square feet per litre of Perma Latex AR and for modified mortar depends upon application and thickness.
Perma Latex AR is available in 10 litre, 25 Litre, 100 Litre and 200 Litre packing.
Perma Latex AR has a shelf life of 24 months when stored as recommended in original packing in a cool and dry place above 5°C.
