FLOOR COATING ON GREEN AND DAMP CONCRETE
In new construction the delay before fresh concrete slabs can be coated and allow the building works to continue, or the area to be put into service is a major problem. In refurbishment projects waiting for existing concrete moisture content to reduce to an acceptable level for over coating with impermeable resin coatings is also a big problem. Sika® EpoCem® Technology is an innovative solution that can be used to reduce all of this waiting time dramatically.
Save with Sika® EpoCem® technology
Suitable for a concrete substrate which doesn’t have yet ideal condition for application. The floor finishes are usually done under time pressure. If you have to wait until the ideal conditions (pull-off strength 1.5 N/mm2) and humidity (<4 % pbv) in the concrete slab are achieved, then most flooring materials require a waiting time of at least 28 days, according to their data sheets and the respective standards.
You can cut this waiting time significantly by using the unique intermediate layers Sikafloor®-81 or -82 EpoCem®. These can be applied directly onto the new concrete after just 7 to 10 days and also directly on concrete substrates recently prepared by high pressure water-jetting, in refurbishment works for example. The benefit is substantial.
