KOROSEAL
SURFACE PROTECTION AGAINST PREMATURE
DRYING OUT FOR KORODUR INDUSTRIAL FLOORS
AND CEMENTITIOUS SCREEDS
APPLICATION
Acc. to DIN 18353 „Screed works"and DIN 18560 „Screeds in building construction", cementitious screeds have to be protected from irregular drying out. It is not only the correct composition of the hard aggregate mortar and skilled workmanship, but also the correct curing which dictates the quality of a KORODUR industrial floor. KOROSEAL has proved its qualities for years already.
This is specially relevant under conditions of high temperatures, low atmospheric humidity and in areas where there is a strong air draught. These circumstances influence the evaporation rate of freshly installed screeds and require professional curing, e. g. with KOROSEAL. The spraying of a liquid curing agent is the most economical method for freshly installed screeds.
PROPERTIES
KOROSEAL renders, after drying, a glossy protection coat on the surface.
This means:
- preventive against contraction cracking tendency
- closing of pores on the surface
- improvement of the strength properties in the layer close to the surface
- reduction of too rapid drying out
Special additves provide after transparent drying out of KOROSEAL a deep surface gloss, which in former times could be achieved only by using solvents. KOROSEAL contains no harmful components (chlorides). It is no paraffin, wax or oil emulsion.
TECHNICAL DATA
colour and condition: white liquid
main component: butadien-styrolcopolymere
density (20°C): 1,02 g/m3
soluble: in water
processing temperature: > 5°C
surface temperature: > 5°C
barrier effect:
60% in middle after 7 days
PROCESSING
Before using, stir KOROSEAL thoroughly. Latest after the final smoothing of the floor, KOROSEAL must be sprayed undiluted, as fine fog, uniformly covering the matt-damp surface. The earlier the application takes place the more effective is the protection.
Before applying KOROSEAL, the surface must be free from water puddles.
Similar to paint spraying process care should be taken not to spray too much KOROSEAL in one place thus to avoid unsightly appearance.
Standard spraying equipment with suitable nozzles is fit for applying KOROSEAL. All equipment should be cleaned carefully with water after use. As an alternative a lambskin roller may be used, which, however, increases the consumption fo the material.
The fresh curing coat has a white appearance. After drying KOROSEAL provides a transparent, glossy coat.
For additionally planned paints or coats on organic basis, e. g. acrylic resin, prior tests are indispensable. Reaction resin products, e. g. EP or PU systems are not recommended.
CONSUMPTION
Approx. 100 - 150 g/m2, depending on the roughness of surface.
