Application
Application methods First mix A component, then add B component, mix the components until a uniform consistency, but not for less than 3 minutes. After the initial mixing, the material is to be poured into a separate container and the mixing must be continued. Quartz sand (best of 0.1~0.3mm fraction) may be added to the mixed A and B components, if required. Please note that the addition of an aggregate can only be done in the case of using resin in self-distribution systems and adding it causes deterioration of the self-distribution properties and a tendency to bleed. The material must be mixed for other 2 minutes until a homogeneous blend. Stirring ratios of Component A and Component B are indicated on the packaging and they must not be changed. Changing the proportions results in a product with characteristics different from the ones declared by the manufacturer. Over mixing can cause air entrainment and therefore it should be avoided. Use low speed electric stirrer for the resin mixing (300 ~ 400 rpm) or another suitable equipment. No foreign substances such as solvents can be added to the resin.
Self-distributing system Apply on hardened and primed substrate (SICONOFLOOR GF-E substrate) SICONOFLOOR PU-HB to the desired thickness using a trowel or squeegee on special teeth. So distributed resin must be bleed using a roller with spikes. Light loads are possible after 24 hours from the of the last layer application. Wash tools with acetone or xylene immediately after use. Hardened or cured material can only be removed mechanically.
Sprinkled system (anti-slip, for internal use) Apply properly mixed resin on the hardened, primed and sprinkled substrate using a metal trowel until evenly distribution of the resin on the desired surface. So distributed material should be sprinkled with the aggregate of the desired fraction to fully cover the resin (invisible colorful spots after SICONOFLOOR PU-HB material). After a minimum of 24 hours application of Sika floor PU-HB as a varnish on the sprinkled system can be started. Excess of aggregate which did not bind with the resin must be carefully swept, so there were no non-grain aggregate on the flooring. The material after thorough components mixing should be applied using a metal trowel or an appropriate chemical resistant rubber trowel, depending on the desired degree of roughness. Apply the material until the total flooring coating with an even coating of resin. So prepared surface is left to cure. Light loads are possible after 24 hours from the of the last layer application. Please note that it is necessary to apply varnish closing the entire system because there is a risk of the floor discoloration.
Conditions of the system components storage Store it in a dry place at +5~30oC. Components A an B in a liquid state are the agents causing water pollution and should not get into drains, soil and watercourses. At the cured state the resin is environmentally neutral. It is unacceptable to store components in open buckets.
