KOROTEX
SURFACE PROTECTION AGAINST PREMATURE
DRYING OUT FOR KORODUR INDUSTRIAL FLOORS
AND CEMENTITIOUS SCREEDS
APPLICATION
Acc. to DIN 18353 „Screed works" and to DIN 18560 „Floor screeds in building construction" cementitious screeds have to be protected from irregular and too rapid 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.
KOROTEX has proved its qualities for years already. Curing with KOROTEX 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 KOROTEX. The spraying of
KOROTEX is the most economical method for freshly installed screeds.
PROPERTIES
KOROTEX renders, after drying, a glossy protection coat on the surface.
This means:
- full hydration
- prevention of too rapid drying out affecting the quality
- preventive against contraction cracking tendency
- closing of pores on the surface
- improvement of the strength properties in the layer close to the surface
TECHNICAL DATA
colour and condition: white liquid
main component: butadien-styrolcopolymere
density: 1,01 g/m3
soluble: in water
processing temperature: > 5°C
surface temperature: > 5°C
PROCESSING
Before using, stir KOROTEX thoroughly. Latest after the final smoothing of the KORODUR floor resp. the cementitious screed, KOROTEX must be sprayed undiluted, as fine fog, uniformlycovering the matt-damp surface. The earlier the application takes place the more effective is the protection.
Before applying KOROTEX, the surface must be free from water puddles. Similar to paint spraying process care should be taken not to spray too much KOROTEX in one place to avoid unsightly appearance.
Standard spraying equipment with suitable nozzles is fit for applying KOROTEX. All equipment should be cleaned carefully with water after use. As an alternative a lambskin roller may be used, which, however, increases the consumption of the material.
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. 150 g/m2
