Thorough substrate preparation is essential. Concrete repairs should be prepared with squared off edges having a 10mm minimum vertical lip.
Remove all loose material – wire brushing is advisable. Sweep clean or vacuum.
The surface must be free from grease, oil or contamination.
Ensure concrete is dry (moisture content not exceeding 5%) before priming.
Caution – Cretex Fastset is a methyl methacrylate based resin and has a characteristic odour during the vaporising of the solvent.
Although non-toxic and non-injurious to health, this can cause tainting and OPEN food products should therefore be removed or sealed during and following application until the vapour has dispersed.
The substrate should first be primed with Polycote MC Primer, brushing thoroughly into the entire surface.
Once applied, sprinkle 0.5-0.9mm Calcined Bauxite or a suitable kiln-dried quartz aggregate onto the WET PRIMER to provide a mechanical surface key for the material.
Allow the primer to cure, normally within 40 minutes.
Using a clean plastic bucket of at least 25L capacity, add the resin to the powder and mix for 3 minutes using a heavy duty slow speed drill with a 0-15 litre mixing paddle until a homogenous mix is achieved.
Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation.
The material should be placed immediately after mixing.
Trowel out to the required smoothness. DO NOT TAMP as this may cause the resin to rise to the surface leaving a weakened bond at the base of the repair material.
Where the depth of repair requires more than one layer (see 'Application Thickness') MC Primer should be applied between layers to aid inter-section bonding – see 'Priming'.
For vertical repairs – where step nosings or expansion joint edges have broken away, the vertical face of the repair material should be supported to prevent slumping.
Suitable sized wooden shuttering should be covered with polythene to reduce adhesion, and should be removed as soon as the material is firm.
