Floor varnish with hardener from ICA

OP600 matt polyurethane varnish with C600P catalyst from the ICA.

Polyurethane varnishes for flooring are known for their hardness, very good resistance to scratching and mechanical shock. So is this solvent-based polyurethane varnish which is used in a 1:1 mix with C600P catalyst. It is recommended for wooden floors in high-traffic areas, such as shops, or those subject to aggression, such as gyms.

The varnish has a slightly yellowish colour and gloss 30. This means it is a matt varnish. Matt varnish is easier to maintain and any defects (scratches, stains) are less visible.

Application

The varnish is shaken very well in the original packaging and then mixed in 100% proportion with the catalyst C600P. To avoid wastage it is best to mix smaller quantities of the material to be used and then prepare a further quantity. This avoids hardening of the varnish and loss of varnish if you cannot use the whole quantity within 2-3 hours. The pot life of the mixture (the time until it starts to harden) is 120 min. The time depends on the temperature and decreases with increasing temperature. The 120 min interval is valid for a temperature of 20ºC.

The C600P catalyst does not need to be mixed with water because it hardens instantly. If after use there is still a quantity of catalyst left over, the container should be tightly closed because over time the varnish may react with moisture in the air and harden.

Application is done with a microfibre mop. The quantity applied per coat is between 70 and 100 g/m². In 50 min the varnish dries superficially so that it can be handled (drying to the print - if you put your hand on the surface of the varnish the print will not remain printed). Total drying takes 90-120 min. After this time it can be sanded if desired. Sanding is done with 240-280 grit sandpaper or fine abrasive sponges. For a finer surface 320-340 grit paper can be used. Sanding between coats is not compulsory, but it gives a much nicer surface finish.

After sanding and sanding, another coat is applied under the same conditions as the first. If the surface is smooth, a second coat of varnish can be applied after 90-120 min, without intermediate grinding. A maximum of 3 coats can be applied.

The substrate to which the varnish is applied

In order to achieve a straight surface it is good to prepare the wooden floors before applying varnish. To repair any imperfections and to straighten it, the floor is grouted. After sanding the putty, a coat of polyurethane primer is applied to ensure as flat a surface as possible on which to spread the varnish. The primer is allowed to dry completely, then sanded with 220-280 sandpaper and sanded off. The varnish is applied to the prepared surface.

Polyurethane varnishes are those with which you can obtain very hard surfaces, resistant to scratches, mechanical shocks and chemicals. They are varnishes that can be used to protect floors in highly stressed areas. Take advantage of the offer because it really is an opportunity. Even if you don't use it now, unmixed products last for a year in the original packaging.
