Cretex® MC CSG is an extremely fast-curing, low temperature acrylic-based concrete floor repair.
It has an incredible 75N/mm² compressive strength after 2 hours and can cure at very low temperatures, down to -40oC.
Its extreme curing characteristics make Cretex MC CSG ideal for rapid repairs to floors, steps, nosing,
kerbs and expansion joint in areas of constant traffic. It may be used to improve the mechanical resistance and load-bearing characteristics of concrete floors. Cold Store Grade is ideal for use in very low temperature environments such as cold stores and exterior applications in harsh climates.
Pot life: 15-20 mins @ -40°C – 0°C
Application thickness: 4mm minimum (although feather-edging is possible) to 15mm maximum in one layer.
For repair depths exceeding 15mm, Cretex MC Deepfill should be used.
This may be applied in layers of up to 50mm thick.
Initial cure time: 45 mins (foot traffic)
Full strength cure time: 2 hours
Full compressive strength: 75N/mm2
Full tensile strength: 7.6N/mm2
Full flexural strength: 24N/mm2
Number of parts supplied: 3
Coverage: 16.0kg unit of Cretex MC CSG when mixed with 1.4L of resin is approximately 1m² at 8mm nominal thickness
Priming required: Priming is required for porous or unstable surfaces – Use MC Primer Std for above freezing and MC Primer CSG for 0°C or below
Please consult the technical data sheet for full technical product data.
Surface Preparation – THOROUGH SUBSTRATE PREPARATION IS ESSENTIAL.
Concrete repairs should be prepared with squared off edges having a 4mm 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 MC CSG is methyl methacrylate based 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.
Priming
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.
Mixing
Using a clean plastic bucket of at least 25L capacity, mix the resin with the 300gms hardener. Then add the 15kg powder and fully 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.
Tip: For Cold Store Grade – the workable life of the material will be maximised if it has been stored at a very low temperature (e.g. in the code store itself) prior to mixing.
Application
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’ on the front of this sheet) 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.
Cretex MC may also be used for screeding and cove-forming – please contact Polycote Technical Helpline.
