Cretex® MC Std is an extremely fast cure / low temperature acrylic-based concrete repair
It has an incredible 75kN/mm² compressive strength after 2 hours.
Cretex MC is a three-part acrylic resin based heavy duty floor repair material designed for use at extremely low temperatures and having very rapid curing characteristics. It offers excellent impact and chemical resistance and may be used for both interior and exterior repairs.
Typical Uses
Its extreme curing characteristics make Cretex MC 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.
Suitable Substrates
Cretex MC may be applied to clean, dry concrete with a moisture content not exceeding 5%.
Colour
Cretex MC is grey in colour.
Packaging
Cretex MC is supplied in pre-measured 3-part units comprising a 15kg powder pack, 150gm hardener powder and 1.4L of resin.
Pot life: 10-15 mins @ 10°C
Application temperature: 0°C – 30°C
Application thickness: 4mm minimum 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: 75kN/mm2
Full tensile strength: 7.8kN/mm2
Full flexural strength: 24kN/mm2
Number of parts supplied: 3
Coverage: The coverage rate per 15.0kg unit of Cretex MC when mixed with 1.4L of resin is approximately 1m² at 8mm nominal thickness.
Priming required: The substrate should first be primed with Polycote MC Primer, brushing thoroughly into the entire surface. Allow the primer to cure, normally within 40 minutes.
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 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. 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 powder. 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 cold 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.
Application Thickness
The recommended range of application thickness of Cretex MC is from 4mm minimum 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.
