Product Description :Two component water based system for waterproofing & wall coating.Water Barrier coat is two component water based, breathable system with excellent bonding properties to the wet substrate.

Application:
1. Water proofing interior and exterior - of concrete, concrete blocks, brick, fibre cement sheeting, walls and floors. 2. Wall coating for partition wall. 3. Primer onto wet concrete.

Applied by brush, roller or conventional spray equipment.

Advantages :
● Suitable for potable water application ● Clean up with water ● Excellent adhesion to damp or dry surfaces, including freshly poured concrete. ● Non flammable ● Can be over-coated with conventional paints. ● Breathable ● Can be developed as an excellent coating by adding compatible pigments to achieve desired colour results

Precautions :
● Water Barrier coat should not be used if substrate temperature is less than 150C ● For optimum results it is always advisable that sufficient air circulation is provided for ● Ensure complete drying and curing of coating. ● Pre-wet the substrate before commencing application of Water Barrier coat

Method of Application :
Remove all loose, defective paint or powdery residues, loose chalk, dust, fungus, algae and foreign matter. Treat any areas affected by fungus growth with Fungicidal Wash Solution. Repair cracks, uneven surfaces with suitable exterior grade fillers. Smoothen the filler areas with sand paper. Surfaces to be painted must be cleaned thoroughly and dry, it must be free from dirt, grease and other foreign matters. Allow all surfaces to dry completely prior to painting. Avoid painting when the moisture content and alkalinity of the walls are still high

Preparation
1. Surface Pre-treatment Concrete: Should be free from grease and oil if necessary, clean with industrial grade degreasing agents. Once clean, steps must be taken to remove laitance, this is best carried out by using: 1.1 High pressure water or wet grit blast. It is not necessary to dry the concrete before applying the Water Barrier coat .Damaged surface should be repaired. Prime with water Barrier coat. While still tacky fill voids with a mortar made 1 part mix to 2 parts sand / cement mix. Leave at least two hours before over coating with Water Barrier coat. If sanding required leave a minimum of 12 hours.
2. Painted Surface Steps should be taken to remove all paint from the surface. 2.1 Concrete & Masonry The surface may be either flame-cleaned, or mechanically treated with a scotching tool.
3. Brick, sandstone, plaster Brick etc, should be clean and free from dust, loose material and efflorescence.
4. Fibre Cement Should be cleaned and free from dust.
2. MIXING RATIO of Component A to Component B is 1 : 1 by Volume 1.5 : 1 by Weight

Application Procedure :
Coating
Mix Ratio (by Volume) 1st Coat 2nd Coat
Component A 1 1
Component B 1 1
Tap Water 1 0.5

The resin and hardener should be thoroughly mixed together in equal portion by volume. Water is than added to reduce the mix to the desired consistency to a maximum of 1 part water to 1 part of resin/hardener mix.

Note : These water addition should be adhered to, for best water proofing results. It is essential that the correct mixing ratio be used and that the resin and hardener are thoroughly mixed together before use. Inaccuracies will result in a lowering of the physical properties of the cured system and if the error is sufficiently great, the system may not cure sufficiently.

Usable Life :
Usable life : 45-60 minutes @ 25oC Note : Should not be used if temperature of substrate is below 150C, not be subjected to normal traffic/use in less than 7 days at normal temperature.

Coverage:
Coverage smooth surface 1st coat 4 - 6 m2 per liter
2nd coat 5 - 7 m2 per liter
This coverage depends on surface porosity and water addition. Decrease in coverage by up to 50% on rough surface can be expected.

Cure Time :
Cure Time @ 25o C Initial Cure 12 - 24 hours
Full Cure 7 days

Recoat Time :

Under normal conditions second coat may be applied after 2 hours but no longer than 24 hours. Epoxy systems tend to yellow on exposure to ultra-violet light, for external decorative application, it is recommend that water Barrier coat be over coated with a conventional paint system. Allow at least 24 hours cure before applying conventional house paints wall paper, floor coverings etc.

Colouring :
Water Barrier coat is white in colour. But it may be pigmented to pastel shade with standard tinters for emulsion paints

Clean Up :
Any spillages should be cleaned up as they occur. Use dry sand or sawdust to soak up bulk of large spillages, and deposit in to waste drums. Clean up small spillages before they set with warm water and detergent.

Storage & Self Life:
Store the components at 18-25oC, in tightly sealed and dry, if possible, in original containers. Under these conditions, the product has a shelf life of at least 12 months. Partly emptied containers should be closed tightly immediately after use. ventilated area, away from heat, direct sunlight, sparks and children. It contains inflammable solvents. Handle with care. Mix resin and hardener as per the ratio. Use the mix solution within the pot life time.

Packaging
Starowall Protect is available in 20 kgs. & 200 kgs. plastic drums

Handling & Safety Caution Stanrose® advance Material products are generally quite harmless to handle provided that certain precautions normally taken when handling chemicals are observed. The uncured material must not, for instance, be allowed to come into contact with foodstuffs or food utensils, and measured should also be taken to prevent the uncured materials from coming into contact with skin, since people with particularly sensitive skin may be affected. The wearing or impervious rubber or plastic gloves will normally be necessary; likewise the use of eye protection. The skin should be thoroughly cleansed at the end of each working period by washing with soap and warm water. The use of solvents is to be avoided. Disposable paper - not cloth towels should be used to dry the skin. Adequate ventilation of the working area is recommended. Please refer to Stanrose® Advance Materials Material Data sheets for the individual products. These publications are available on request and should be referred to for fuller information.
