M-ROOF 200 – Single Component Acrylic Roof Membrane
MaxPro 200 Flexible acrylic high build waterproof membrane. Is single pack water based high build acrylic waterproof membrane.
The product is supplied ready to use and is ideal for waterproofing flat roofs, pitched roofs, gutters, felt and fibreglass. The product has
high build properties allowing it to be applied up to 1-2 mm thickness in one coat
MaxPro 200 is formulated using a complex range of acrylic resins, fillers and polymers which combine to provide a high-performance waterproofing membrane with long-term UV stability and corrosion resistance.

- Allow for curing
- Inspect the coating for any pinholes or misses and repair where necessary
Degrease the repair area with MEK or similar solvent to remove any surface contamination, using angular grit, grit-blast to SO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) and a minimum blast profile of 75 microns.
Once blast cleaned, the surface must be dust free and cleaned again using MEK or similar solvent. All surfaces must be repaired or coated before oxidation or gingering occurs.
Surface Preparation Concrete
Concrete shall be a minimum of 21 days old, and the residual moisture content shall be 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 shall be made good using a proprietary repair compound, e.g. MaxCrete 200 concrete repair mortar.
Block work shall be sealed using MaxPrime 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.
Surface preparation Mineral based substrates
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.
All surfaces will require priming using Maxprime 100 for a porous substrate such as mineral felt, concrete. Non-porous surfaces use MaxPrime 300; both primers should be applied as detailed on the relevant data sheet.
Strip-coat all joints seams and up-stands incorporating the polyester reinforcement sheet. Typically 75.0mm either side of the joint giving a stripe coat of 150mm.
Application Base Coat
Mix and apply the material directly to the primes surface, using a soft-bristled brush, squeegee. Check the wet film thickness on a regular basis ensuring correct coating thickness of a minimum 500. While the base coat is wet embed the glass fibre reinforcing sheet ensuring no blisters or creases, and allow to dry.
Application Top Coat
Mix and apply the material directly to the base-coat, using a soft-bristled brush or squeegee. Check the wet film thickness on a regular basis ensuring correct coating thickness of a minimum 500.
Ideally, the reinforcing sheet should just be visible after the top-coat is applied.
1ltr of the product will cover 2.0 sq metres at a nominal thickness of 500 microns.
Usable life at 20°C
Minimum – the applied material can be over-coated as soon as it is touch dry.
Maximum – over-coating time 36 hours
