General

1. Bitumat Synroof Hi-build, an elastomeric, premium acrylic coating, may be applied by brush, roller, squeegee or spray equipment depending on site conditions. To spray, select a nozzle size of at least 0.028 in.; first checking the spray equipment to ensure suitability.


2. All surfaces to be coated must be clean, dry, and free from dust, dirt, oil, and other contaminants.


3. Coverage varies depending on factors such as type and quality of substrates i.e. surface regularity and application method.


4. Apply in separate coats, each at a right angle to the one before. Using a different colour for each coat helps to ensure consistency of cover.


5. The final coating thickness to be achieved depends on the requirements of the individual roof. A final dry film thickness between 0.5 and 1.5mm may be built-up.

Preparation
Surface preparation is a very vital issue and this influences the integrity of the waterproofing systems. Hence, care must be exercised when the preparation is done. This is very important when re-roofing over an existing old roof is done. Instruction should be followed strictly.

1. All surfaces to be smooth, clean, dry, and free from dust, rust, and laitance.


2. Concrete and cementitious substrates must be well compacted with a wood float type finish, be at least 28 days old and well dried. Uncured concrete surface will have moisture trapped inside and will turn gaseous when temperature rises.


3. Wooden or metal panels to be firmly fixed in position.


4. Terrazzo Roof Tiles: Clean and repair damaged joints. Ensure that the tiles are firmly grouted. Remove all loose material.


5. Metal Roofs: Wire brush to remove moss, mildew, loose paint, and rust areas, then clean surface with a broom before priming. High pressure water brooming may be used, if necessary.

Priming

1. Old asphalt surface and bituminous roofing felt. Cut felt blisters crosswise, dry and rebound with suitable adhesive. Allow to cure. Then prime cleaned surface with Synroof Hi-build diluted with 50% water.


2. Concrete & Terrazo tile roofs.
   Following removal of all loose and other alien material, prime with Synroof Hi-build diluted with 20% water. Greater dilution may lead to weaker bonding with the substrate.


3. Metal roofs. Clean and remove all rust and apply a rust inhibitive primer. Follow this by applying metal primer to all corroded surfaces.


4. Other roofs. Should algae or fungal growth affect the roof, use a stiff bristled broom to remove this before treating the cleaned surface with a suitable fungicide and apply primer coat by diluting Bitumat Synroof Hi-build with 50% water.

Application

1. Primer must be completely dry before the first coat is applied.


2. Bitumat Synroof Hi-build may be applied by soft brush, roller or spray gun.


3. For spraying, Bitumat Synroof Hi-build may be slightly diluted with water. Too great a dilution may lead to sedimentation and blocking of spray gun.


4. Apply two coats, each at the approximate rate of 0.8 kg/sqm. (Excluding the Bitumat Synroof Hi-build prime coat).


5. Where substantial movement is anticipated in the substructure, mesh reinforcement (60/80 gsm thermobonded polyester as part of a “sandwich” membrane system is used). Lay this mesh in the wet first coat before application of subsequent coats. All detailing to popes, up stands, drains, projected line etc. should be mesh re-enforced in this way.

Curing
Allow 24 hours between coats. A final curing time of 48 hours is adequate at normal working temperatures. Ensure curing is completed before laying thermal insulation boards, mechanical protect, and other coverings.

Low temperature and high atmospheric humidity will slow down the curing rate, and vice versa.

Mechanical Protection
Accessible Roofs: The installed Bitumat Synroof Hi-Build can either be covered by insitu concrete screed or by thermal insulation. Place a nonwoven polyester separation layer over the acrylic waterproofing membrane followed by appropriate thermal insulation boards. Then lay craft paper or polyethylene sheets as separation layer over the insulation boards and place the topping screed of 4 to 5 cms thickness or suitable cement tiles.

Non-Accessible Roof: Place a nonwoven polyester separation layer over the acrylic waterproofing membrane followed by the insulation boards. Cover the insulation with another layer of nonwoven polyester separation layer and place 15/30 gauge washed gavel to a minimum depth of 5c. For thicker insulation boards, the gravel depth should be at least equal to that of board thickness.

Precautions

1. Bitumen or asphalt roof surfaces to receive a coating of Bitumat Synroof Hi-build should be totally dry. Trapped moisture can lead to severe problems later.


2. Never apply if rain is imminent.


3. Application of thick coat at temperature below +5°C may result in incomplete film formation, with reduced elasticity and the possibility of crack forming.


4. Bitumat Synroof Hi-build is resistant to light foot traffic. However, heavy traffic, high heel shoes, furniture, etc. will cause damage. In these cases tiles, slabs, etc should protect the membrane.


5. Do not clean the cured Bitumat Synroof Hi-build coating with brooms that have hard bristles. These may cause damage.


6. Do not use Bitumat Synroof Hi-build on areas that will be constantly submerged in water.

Clean-Up
As a good roofing practice, flush all hoses, equipment and tools with water immediately after use.

Packing
20 kg metal pails, others on request.

Storage
1. Keep away from direct sunlight and preferably store below 30°C and above +5°C.
2. Protect from frost.
3. When stored in unopened containers, expect a minimum shelf life of one year.

Health and Safety

1. Toxicity – non toxic and odorless.


2. Flammability – non-flammable when wet. The cured film will burn but is not a fire hazard.


3. Skin contact – Prolonged contact is to be avoided. Use of a barrier cream or gloves will protect sensitive skins.


4. Cleaning – Remove with water when wet and proprietary hand cleaner when dry.


5. Medical assistance – This should be sought if Bitumat Synroof Hi-build is ingested or comes into contact with eyes. Eyes should be rinsed with copious amount of clean water.


6. Ventilation to the working area is desirable.
