M-ROOF 201 – Single Component High Build Acrylic Roof Memrane

• All oil and grease must be removed from the surface using an appropriate cleaner such as MEK or similar type solvent.
• All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast profile of 75 microns using an angular.
• Once blast cleaned the surface must be degreased and cleaned using MEK or similar type solvent.
• All surfaces must be coated before gingering or oxidation.

• All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
• All surfaces must be mechanically abraded using handheld grinders to ISO 8501/4 ST3 (SSPC SP3 ST3).
• Once abraded, the surface must be degreased and cleaned using MEK or similar type material.
• All surfaces must be repaired before gingering or oxidation occurs.

• Concrete should be a minimum of 21 days old and the residual moisture content below 6%.
• Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound and existing paint finishes etc.
• Blow holes and defective concrete to be made good using a proprietary repair compound, e.g. M-CRETE 200 concrete repair mortar.
• Block work shall be sealed using M-PRIME 100 surface sealer/ primer.
• Suitable mechanical treatment such as vacuum grit blasting is the preferred treatment before application as this ensures a mechanical ‘key’ for the coating.

• Sweep the roof area and remove any medium to large chippings, moss, lichens and other debris, clean with an anti-fungicidal wash if necessary.
• Repair any splits, holes or blistering with a suitable epoxy concrete mortar, duct tape or membrane system.

Single component material:

• The material is at a temperature between 15-25°C.
• Do not apply the material when the ambient or substrate temperature is below 5°C.

• Agitate the product using an electric paddle mixer to ensure you have a consistent mix of acrylic emulsion.

• All surfaces will require priming using M-PRIME 100 for a porous substrate such as mineral felt, concrete.
• Non-porous surfaces use M-PRIME 300; both primers should be applied as detailed on the relevant data sheet.

Brush & Roller

• Stripe coat all edges, joints & corners.
• Once the stripe coat has cured and is capable of being overcoated, apply a basecoat at a minimum wet film thickness 500 microns.
• While the base coat is wet embed the reinforcing sheet ensuring no blisters or creases and allow to dry.
• Once the basecoat has cured sufficiently, apply a topcoat at a minimum wet film thickness of 500 microns.
• Ideally, the reinforcing sheet should just be visible after the top-coat is applied.
