After a few years of installing a wet pour rubber flooring, some EPDM or coated SBR colours may have lost vividness and wear and tear may be visible with some granules crumbling due to loss of binder on the upper part of the top surface.
If the budget does not allow the re topping or full renovation of the safety surfacing, an alternative is the use of our CONICA transparent or pigmented top coatings. The pigmented ones allow to get a vivid colour again as if the surface had been completely renewed.
Our sealing lacquers top coats are polyurethane-based, two-component and can be solvent or water-based, be transparent or pigmented, have a matte or gloss finish and have added anti-slip additives or additives for increased hygiene requirements.
Each of them has its preferred use and this article is aiming to explain some of their main differences to make your choice easier.
Indoor applications
In this case it is preferable to use a water based topcoat to reduce emission levels.
First, the pore sealer CONIPUR 4480 W (transparent) is applied to close the pores of the EPDM layer. As top coat, our type CONIPUR 3202 W is the best choice and is available in a transparent satin matte or pigmented finish in a range of colours with good resistance to UV radiation.
Once the two components are mixed, the mixture can be used for about 1 hour, it must be applied with a “Microtex” roller in two coats, following the instructions on the product’s technical sheet.
Outdoor applications
The ideal sealing lacquers for these applications are mainly pigmented top coats solvent containing and with a satin finish. They have good UV protection and at the same time they improve the wear resistance by also improving the adhesion of the granules. The cleaning and maintenance is facilitated and run-off is improved while also improving the visual appearance of the surface.
Our type CONIPUR 2200 is resistant to sea water, brine and waste water, and to a variety of alkaline substances, diluted acids, mineral oils, lubricants and fuels.
If ,in addition to this you also need anti-slip properties, the CONIPUR 2210 type adds some small particles to give it significant anti-skid improvements.
These top coats should be applied sprayed by using an airless spraying machine, in two coats from opposite directions to ensure the granule is sealed from all sides.
The application by rolling is not recommended, as these are too rough to obtain a homogeneous, optically appealing surface.
All these products can be used for around 1 hour after the two components of resin and hardener are mixed.
After application they are ready for foot traffic in 1 day but a full curing requires around 5 days depending on the climatic conditions.
Take care
