Premium Quality Acrylic Waterproofing Coating.Welcome to Dusk Technology

GENERAL:

• BITUMAT Synroof Hi Build, an elastomeric, premium quality 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 inch; first checking the spray equipment to ensure suitability.
• All surfaces to be coated must be clean, dry, free from dust, dirt, oil and other contaminants.
• Coverage rate varies depending on factors such as type and quality of substrates i.e. surface regularity and application method.
• Apply in separate coats, each at a right angle to the one before. Using a different colour for each coat helps ensure consistency of cover.
• The final coating thickness to be achieved depends on the requirements of the individual roof. A final dry film thickness between 0.5 and 1.5 mm may be built-up.

PRIMING:

• Old asphalt surfaces and bituminous roofing felt. Cut felt blisters crosswise, dry and re-bond with suitable adhesive. Allow to cure.
• Then prime cleaned surface with BITUMAT Synroof Hi Build diluted with 20% water.
• Concrete & Terrazo tile roofs. Following removal of all loose and other alien material, prime with Bitumat Synroof Hi-Build
  diluted with 20% water. Greater dilution may lead to weaker bonding with the substrate.
• Metal roofs. Clean and remove all rust and apply a rust inhibitive primer. Follow this by applying metal primer to all corroded surfaces.
• 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 BITUMAT Synroof Hi Build with 20% water.

PREPARATION:

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

Instructions should be followed strictly.

• All surfaces to be smooth, clean, dry and free from dust, rust and laitance.
• Concrete and cementitious substrates must be well compacted with a wood float type finish, be at least 28 days old and well dried.

Un-cured concrete surface will have moisture trapped inside and will turn gaseous when temperature rises. This will lead to blistering and even delamination from the surface.

• Wooden or metal panels to be firmly fixed in position.
• Terrazo roof tiles: Clean and repair damaged joints. Ensure that the tiles are firmly grouted. Remove all loose material.
• Metal Roofs: Wire brush to remove moss, mildew, loose paint, and rust areas, then clean surfaces with a broom before priming.
  High pressure water booming may be used, if necessary

APPLICATION:

• Primer must be completely dry before the first coat is applied.
• BITUMAT SYNROOF HI-BUILD may be applied by soft brush, roller or spray gun.
• For spraying, BITUMAT Synroof Hi Build may be slightly diluted with water. To great a dilution may lead to sedimentation and blocking of spray gun.
• Apply two coats, each at the approximate rate of 0.8 Kg/Sqm. (excluding the BITUMAT SYNROOF HI-BUILD prime coat).
• Where substantial movement is anticipated in the substructure, a mesh reinforcement (60/80 gsm thermo-bonded 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 pipes, upstands, drains, projected line etc. should be mesh re-inforced 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 protect and other coverings.

MECHANICAL PROTECTION

Accessible roofs. The installed BITUMAT SYNROOF HI-BUILD can either be covered by insitu concrete screed or by thermal insulation. Place a non-woven polyester separation layer over the acrylic waterproofing membrane followed by appropriate thermal insulation boards. Then lay kraft 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 roofs. Place a non-woven 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 5cm. For thicker insulation boards, the gravel depth should be at least equal to that of board thickness.

CLEAN-UP

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