Does a surface sealing on a freshly layed screed flooring require mechanical preparation (ie: shotblasting etc)?
The substrate must be prepared using suitable methods, so that an open-pored surface suitable to receive coatings is achieved. All adhesion inhibiting substances must be removed. This can be carried out by blast cleaning techniques, planing or similar methods.
At what stage do cement bonded substrates achieve the required remaining moisture content of 4% when applying reactive epoxy resin coated surfaces ?
This depends on the layered thickness of the required construction and ambient environmental conditions. The required moisture content can be achieved after a period of 28 days, in general for cement screed surfaces and after approx. 3 months for applied monolithic concrete substrates.
Is it possible to prepare a reactive epoxy resin coated surface on cement bonded substrates prior to achieving the required remaining moisture content of 4% and without causing the subsequent effects of blisturing (vapour diffusion pressure, osmosis) ?
Yes, this is possible with the application of the
special primer ASODUR-SG2.
Is it possible to coat sharply inclined surfaces or walls with reactive epoxy resin coatings ?
Yes, with addition of suspending agents (thixotropic agents)
such as the ASO-Fibre filling material.
Can the curing time of the 2 K-Epoxy or PU-resins be influenced by additional application of different curing quantities ?
No, due to the variation of the specified mix ratio the surplus components can not bind ie: the coating does not harden or would harden leaving an uneven state (soft parts).
Which type of equipment and/or tools are required for application of epoxy resin coatings ?
Mixing the components: with a slow running mixer or hand drill (approx. 300 rpm) (Seperate to the Pail supplied), with mixing rod affixed, mixing paddle and Spirit level.
Application of the coat in rolled method: using a brush, or lint free, solvent resistant fur roll.
Application using the Spactling method (running coat): with trowel and/or scraper, serrated scraper, spiked roller, wearing spiked shoes for easier grip.
When do I need to deaerate a resin floor coating with a spiked roller?
With coatings where the material consumption is from 1.5 kg/m² or greater per coat. The dearation process should not be carried out until approx. 20 minutes after product application.
Why does the 2-component epoxy resin react so quickly that the material cannot be processed continuously?
Temperature of the material and substrate as well as the stated pot life are substantial for the reaction of the material. After the material has been mixed (see details in the technical data sheet)it has to be spread onto the substrate immediately so that the material can immediately take over the temperature of the substrate which results in a prolonged material reaction time. The more compact the material is in its bucket the quicker is the material reaction time. A processing container with large diameter should be used. Never process the material directly out of the supplied buckets.
