Cemcoat is a fast curing, durable cementitious screed that can be used for many applications, whether it be the protection of old concrete from freeze/thaw issues to the coating of wooden sheeting for a temporary pathway across a building site. It is extremely strong and can withstand both heavy vehicular and heavy foot traffic.
Use on: Concrete, tarmac, wood, metal, plastic, galvanised metal, iron, fibreglass, asbestos, PU foam, etc Use where: Internal/External Typical industries: Used in all industrial, commercial and domestic areas. Heavily used in multi-story car parks, industrial yards and within the farming industry in areas such as grain stores, dairies, piggeries, abattoirs and silage clamps Type of job: Cemcoat is commonly used for adding slip resistance and smoothing out and protecting surfaces on loading and parking bays, ramps, wooden walkways, decking, driveways and footpaths. Cemcoat is excellent for vertical surfaces and decorative effects, columns, plinths, planters, etc. and can be easily over coated to further enhance the appearance and / or functional properties Approximate coverage: 35 kg unit - 15 - 20m2 @ 1mm nominal thickness Special features: Heavy duty, impact resistant, flexible, will adhere to damp surfaces, prevents further erosion, can be used as part of a waterproofing system, use on vertical and horizontal surfaces
Pot life: 60 mins @ 20oC Application temperature: 5oC - 25oC Cure time: Re-coat after 4 - 6 hours @ 20oC Light wheeled traffic - 24 hours Full traffic - 3 days Depth of repair (1 layer): 1mm nominal thickness. If a certain thickness or extra durability is required, Cemcoat can be built up by multiple applications. In any case, two coats are normally advised Number of parts supplied: 2 Priming required: No. Dampen porous surfaces prior to application

Thorough substrate preparation is essential.
All surfaces must be clean and free from loose materials. Areas contaminated by oil and grease should be thoroughly cleaned with Polycote Degrease IT.
Defects in existing surfaces must be made good, before applications. Where evidence of organic growth, lichen, moss etc. is apparent, surfaces must be thoroughly cleaned and must be treated with a long term fungicidal/biocidal treatment such as Polycote Destroy IT. Careful attention should be given to areas in both horizontal and vertical surfaces such as cracks and joints where water penetration is possible. Rust etc must be removed and treated with a suitable metal primer such as Polycote ZP Primer.
The ideal mixing tool is a slow speed drill fitted with a multi action mixing paddle. Suitable mixing paddles can be purchased from Polycote.
The unit of material supplied is based on the standard mix of 10 litres of liquid to 25 kgs of powder (i.e. 1 part liquid to 2.5 parts of powder) but it should be noted the ratio of liquid to powder can be adjusted to suit individual applications in terms of surface, usage and prevailing temperature. The ratio can vary from 1 part of liquid to between 1.8 up to 3.75 parts of powder.
For black, buff, terracotta and green versions, the liquid MUST be pre-stirred VIGOROUSLY prior to measuring out the required quantity and adding the appropriate amount of powder. Pour the liquid into a clean open mixing vessel (e.g. the plastic container used to supply the unit). ALWAYS add the powder into the liquid - slowly, continually mixing until all the powder to be used is added. Continue mixing for a further 2 to 3 minutes ensuring there are no lumps in the mix. The final consistency should be similar to that of a thick cream.
Please note: Cemcoat is a balanced formulation and no additional water should be added to the mixture.
Before application of Cemcoat to horizontal or vertical surfaces, ensure that porous surfaces are damp, this can be done simply by spraying a hose over the area. The area must only be damp and no puddles should be present. Ensure any standing water is removed.
Please note: all warm surfaces are best cooled by dampening down with water before application of the Cemcoat. Should you wish to apply a further coat of Cemcoat, a very light spraying of water will again, aid the spread of the material.
CAUTION: Do not apply Cemcoat on hot surfaces or at times of very strong sunlight and high temperatures as this could accelerate the drying of mixed concrete and produce a very rapid cure of the applied material. Although very rare, this situation can subsequently cause hairline cracking.
Cemcoat is extremely simple to apply using either a brush, roller, trowel or squeegee.
From the mixing vessel pour out a quantity of material that can be easily and uniformly spread. When completing larger areas, we advise using our straight bladed squeegee, spreading the Cemcoat out evenly and to the desired thickness / coverage rate. Using a roller and whilst still wet (immediately) , roll out the Cemcoat to a uniform finish. Take care when rolling that each 'roll' is pulled in a neat straight line to achieve the final texture / slip resistance required. Repeat the mixing and application method until the selected area has been completed.
Over coating can be completed as soon as the first coat has dried (between 4 and 6 hours according to climate conditions).
Cemcoat should not be applied where the air or background temperature is likely to fall below 5oC or where there is a risk of rainfall on exposed applications prior to full curing being achieved.
If the aesthetic look is important, we recommend a final sealer coat.
