Preparation & Application of Crosscote
Crosscote Antislip Coating
Crosscote is designed to repair, protect and enhance existing structures, has good wear-resistant properties, and provides excellent slip resistance.It has excellent adhesive characteristics and can be applied to many types of exposed structures where resistance to adverse environmental conditions and ultraviolet light is required. It is capable of accepting normal structural movement without cracking or loosening. Although providing good waterproofing qualities the product is micro-porous and therefore allows a cement type base to breathe, releasing entrapped water vapour therefore not creating any blisters like any floor paints.
The Standard grade of powder is generally used on horizontal surfaces and is suitable for light to medium traffic, providing an excellent anti slip finish; in some situations standard grade can be used for vertical applications.
The Smooth grade is generally used for vertical applications. Hard grade powder is used for applications generally involving heavy traffic movements such as driveways and car parking areas. It is advisable to use the standard grade of powder for the first or bonding coat where hard grade powder is selected as the final finish. In heavy traffic movement conditions or areas receiving high levels of abrasive use up to 3 coats of hard grade powder may be required.
Before application of Crosscote to horizontal or vertical surfaces, ensure that porous surfaces are damp, this can be done simply by spraying a hose over the area to receive the application or alternatively brushing out clean water with a suitable broom.
The area must only be damp and no puddles should be present, any surface water must be removed. Very porous surfaces may be primed in the same way using a mixture of 1 part Crosscote liquid to 10 parts clean cold water.
Please note: all warm surfaces may also be cooled by following this procedure and prior to applying succeeding coats the surface of the previous coat may also be lightly damped with clean cold water following the same procedure; this will also aid the spread of the material.
CAUTION: Do not apply Crosscote on hot surfaces or at times of very strong sunlight and high temperatures as this could accelerate the drying of mixed product and produce a very rapid cure of the applied material
Crosscote is extremely simple to apply. Apply by brush, roller, trowel or squeegee.
From the mixing vessel pour out a quantity of material that can be easily and uniformly spread using the selected tool over the appropriate area and finish to the desired texture before moving on to the next part of the mix. Repeat the mixing and application method until the selected area has been completed.
As soon as a coat has dried, between 1 and 24 hours according to climate conditions, it can be overcoated with the next coat.
Crosscote should not be applied where the air or background temperature is likely to fall below 7o C or where there is a risk of rainfall on exposed applications prior to full curing being achieved.
POT LIFE & CURING TIMES The pot life of mixed Crosscote will vary according to climatic conditions but at an ambient temperature of 20o C will be in the region of 30 minutes; the curing time at this temperature generally between 1 to 6 hours.
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 an oil dispersant cleaner. Defects in existing surfaces must be made good, before applications. Where evidence of organic growth, lichen, moss etc. is apparent, surfaces must be treated with a long term fungicidal/biocidal treatment which should be allowed to react and washed off thoroughly. Careful attention should be given to areas on 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.
The ideal mixing tool is a slow speed drill fitted with a multi-action mixing paddle. The unit of material supplied is based on the standard mix of 20 litres of liquid to 50 kgs of powder ( i.e.1 part of 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 1.75 up to 3.75 parts of powder.
IMPORTANT: only mix a quantity of material at any one time which can be comfortably applied
within the Pot Life period and prevailing conditions at the time of application.
EXAMPLE: 2 litres of liquid mixed with 5 kgs of powder, the standard mix, will yield 5m2 at 1mm nominal thickness ( see coverage guide information ). The liquid should be pre-stirred 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. an open top plastic bucket ) and 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: Crosscote is a balanced formulation and no additional water should be added to the mixture.
COVERAGE The coverage rate per 20 litres of liquid & 50 kgs of powder is approximately 50m2 at 1mm nominal thickness. Please note that the coverage relates to a smooth surface. The coverage on a rough surface such as spalling concrete will be much less.
Crosscote should not be applied in wet conditions or where such conditions are likely to occur before the coating has dried. Dry or porous substrates may be damped or primed prior to application but horizontal surfaces must be free of standing water. Crosscote should not be applied where the air or background temperature is likely to fall below 7°C.
CLEANING Tools and equipment should be cleaned whilst product is still wet with water. Hands and skin should be cleaned immediately by washing with soap and water.
