What is the best product to clean a resin screed in a kitchen?

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.

What preparation equipment is required for a normal concrete floor?

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.

Is there a lot of dust produced during preparation?

Regardless of what method is used to prepare a floor there should be minimal dust if the correct procedure is used.

Can epoxy coatings be made in any colour?
