Epoxy resins are widely used in the manufacture of paints, adhesives, fibre re-enforced plastic, electrical insulation etc. Usually, in paint manufacture, the epoxy resin is supplied as a two-part mix and ‘cross-linked’ with another component this is usually referred to as the hardener.
In general terms epoxy resins are not UV stable however there are other products that can be used that resist UV
Floor coatings are made anti-slip by incorporating an aggregate either in with the paint or more normally broadcast into the paint when wet.
Expansion joints are usually filled with a flexible joint sealant. Sometimes if the joint is not in good condition it can be filled and then re-cut and flexible joint filler would then be used.
A polyurethane coating usually has more flexibility and in certain situations better chemical resistance
PTV stands for pendulum test value results are achieved when using the correct appropriate equipment. 0-24 rates as high slip potential – 25-35 has moderate slip potential and 36+ is considered low slip potential.
A resin screed is normally made up of a resin and filler or an aggregate. Usually, the resin is mixed in a large mixer and the filler or is then added and the resultant mixture is then applied by trowel
There are various types of resin screeds available in various usually ranging from 3mm – 9mm with a wide range of finishes and colours.
Yes, you can form a cove.
This will depend on the temperature, epoxies stop curing below about 5 degrees centigrade, the warmer the temperature the quicker the cure. Usually, epoxies require twenty-four hours to cure with the full cure taking place over 3-5 days. It is possible to accelerate the cure using a fats cure additive.
Depending on the type of epoxy, solvent-based epoxies will have an odour; solvent-free systems have a very low odour
The same answer as epoxy coatings it will depend on the type of polyurethane used.
It is not advisable to apply any floor coating to an oil-contaminated floor without expert advice. Preparation using the correct equipment will help and oil tolerant primers are available.
It is important that careful consideration is given and expert advice is to sort of moisture is suspected on a floor. Depending on the situation moisture tolerant primers are available and may be effective depending on the level of moisture – if there are any doubts tests should be undertaken.
This will depend entirely on how the floor is used, the footfall and the original specification. For example, three coats of epoxy applied at a film thickness of 500 – 700 microns will last a lot longer than one coat. Epoxy floor coatings tend to have very hardwearing properties.
The Ferfa guide to cleaning resin floors as follows:
Floor cleaning can be thought of as having two components, a mechanical component and chemical component; these two components should work together to mutual advantage.
The mechanical component – energy – may be applied to the floor by hand with a scrubbing motion. Usually, the input is by mechanical agitation, a floor scrubber. High-energy inputs may also be achieved by using high-pressure washers, hot water washers and steam cleaners.
The chemical component, cleaning solution, will dissolve or emulsify the type of soil or contamination present. Once this has taken place the removal of the dirty water and rinsing of the floor are key to successful cleaning. It is important that clean water is used for rinsing.
Resin flooring will not be affected by most generally available special purpose cleaning materials, when these are used in accordance with the Chemical Cleaning Manufacturers’ instructions and the floor rinsed properly with clean water. Specific cleaning instructions should also be sought from the resin-flooring manufacturer.
A small spot test in an inconspicuous area is a worthwhile precaution before applying any new cleaning product.
The cleaning regime should specify the type of equipment to be used, the type of cleaning chemicals to be used, frequency of the cleaning, together with an appropriate Risk Assessment and PPE items.
Each cleaning regime will be specific for a particular set of conditions. Should any of the factors vary e.g. the type of soiling, then a change in the cleaning chemicals may be required. In order that the floor continues to provide the intended performance and meets the hygiene requirements, then it is essential that the user implements the appropriate cleaning regime.
Normally a floor is prepared using a diamond headed grinder fitted with vacuum extraction. In some cases large floors and uneven floors can be prepared by shot blasting.
Regardless of what method is used to prepare a floor there should be minimal dust if the correct procedure is used.
This will depend on the manufacturer and the quantities involved, usually most colours can be manufactured in RAL and BS 4800 colours.
