DESCRIPTION

 SYNROOF HI-BUILD is an elastometric, single pack roofing compound. Based on special Acrylic Polymers, it is ideal for dry substrate where it forms a seamless, joint free, water and weather tight elastic membrane.

USES

Existing Roofs. SYNROOF HI-BUILD is suitable for roofs ranging from asphalt and asbestos cement to terrazzo tiles and concrete. The substrate may be horizontal or inclined. Use as a waterproofing membrane in traditional (warm roof), un-insulated and inverted roof structures.

PACKING

20 kg. metal pails. Other containers are available to special order.

INSTALLATION GENERAL

1. SYNROOF HI-BUILD may be applied by brush, roller, squeegee or spray The actual method of application depends 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 grease and other
3. Coverage varies and depends on factors such as type and quality of substrates e. regularity of surface and method of application.
4. Apply in separate coats each at a right angle to the one before. Using a different colour for each coat helps ensure consistency of
5. The final coating thickness to be achieved depends on the requirements of the individual A final dry film thickness between 0.5 and 1.5 mm may be built up.

PREPARATION

1. All surfaces to be smooth, clean, dry and free from dust, rust and laitence
2. Concrete and cementitious substrates must be well compacted with a wood float type finish, be at least 28 days old and well
3. Wooden or metal panels to be firmly fixed in
4. Terrazzo roof tiles : Clean and repair damaged Remove all loose material.
5. Metal roofs : Wire brush to remove moss, mildew and loose paint. De-rust corroded areas, then clean surfaces with a broom before

PRIMING

1. Old asphalt surfaces and bituminous roofing Cut felt blisters cross wise, dry and re-bond with suitable adhesive. Then prime cleaned surface with SYNROOF HI-BUILD diluted with 20% water.
2. Concrete & Terrazzo tile roofs Prime with synroof Hi-build diluted with 20%
3. Metal Roofs. Clean and remove all rust and apply a rust inhibitive primer. Follow this by applying metal primer to all corroded
4. Other Roofs. Should the roof be affected by algae or fungal growth, use a stiff bristled broom to remove this, before treating the cleaned surface with a suitable fungicide, and apply primer coat by diluting SYNROOF HI-BUILD with 20% water.

APPLICATION

1. Primer must be completely
2. SYNROOF HI-BUILD may be applied by soft brush, roller or spray gun
3. For spraying, 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 8 kg/sq. m, to provide a total of about 1.5 to 2 kg/sq. m (including the SYNROOF prime coat).
5. Where substantial movement is anticipated in the substructure, reinforce SYNROOF HI-BUILD by incorporating a mesh reinforcement as part of a “sandwich” membrane system. Lay this mesh in the wet first coat before application of subsequent All detailing to pipes, upstands, drains, projected line etc. should be mesh reinforced 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 complete before laying thermal insulation boards, mechanical protection and other coverings. Low temperatures and high atmospheric humidity will slow down the curing rate, and vice versa.

THERMAL INSULATION

Joint extruded polystyrene panels with 100% closed cell structure may be placed over the SYNROOF  HI-BUILD     membrane. Board thickness is determined by the required level of insulation. Boards to be laid staggered and allowance made for the thermal movement.

MECHANICAL PROTECTION

Accessible roofs can be protected by in-situ concrete screed. Place a non woven polyester separation layer (Alyat or similar) over the acrylic waterproofing membrane followed by insulation boards. Then lay kraft paper or polythene sheets as separation layer over the insulation boards and place the topping screed of 4 cm to 5 cm 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 non woven polyester separation layer and place 15/30 gauge washed gravel to a minimum depth of 5 cm. For thicker insulation boards, the gravel depth should be at least equal to that of board thickness.

STORAGE

Keep away from direct sunlight and preferably Protect from frost. When stored in unopened containers, expect a minimum shelf life of one year.

PRECAUTIONS

• Bitumen or asphalt roof surfaces to receive a coating of SYNROOF HI-BUILD should be thoroughly
• Never apply if rain is he possibility of crack forming.
• SYNROOF HI-BUILD is resistant to light foot traffic, however, heavy traffic, high heel shoes, furniture, etc. will cause damage. In these cases the membrane should be protected by tiles, slabs, etc.
• Do not clean the cured SYNROOF HI-BUILD coating with brooms that have hard These may cause damage.
• Do not use SYNROOF HI-BUILD on areas that will be constantly submerged in

HEALTH & SAFETY

1. Toxicity – non toxic and odourless
2. Flammability – Non flammable when The cured film will burn but is not a fire hazard.
3. Skin contact – Prolonged contact is to be Use of a barrier cream or gloves will protect sensitive skins.
4. Cleaning – Remove with water when wet and proprietary hand cleaner when
5. Medical assistance – This should be sought if SYNROOF HI-BUILD is ingested or comes into contact with Eyes should be rinsed with copious amounts of clean water.
