Method
  • Prepare the surface 
  • Prime all surfaces
  • Stripe coat all joints and seams
  • Apply the base-coat at a  target film thickness of 500 microns
  • Install reinforcing sheet
  • Apply top-coat at a target film thickness of 500 microns
  • Allow for curing
  • Inspect the coating for any pinholes or misses and repair where necessary
Surface Preparationsteel:

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.

Priming

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

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. 

Coverage

1ltr of the product will cover 2.0 sq metres at a nominal thickness of 500 microns. 

Usable life at  20°C 

60 minutes

Over-Coating Times 

Minimum – the applied material can be over-coated as soon as it is touch dry. 

Maximum – over-coating time 36 hours

Cure Times @ 20°CMovement without load

MAXCERAM 500 is designed for elevated temperature service in all situations requires post cure.
After an initial cure period of at least 24 hours at 20°C it should be post cured at between 60°C for 24 hours and 100°C for 2 hours.

As an alternative and where service temperature will rise gradually the material can be post cured in service after an initial cure period of at least 24 hours at 20°C
