PRODUCT MIXING AND APPLICATION

40 Kg need approx 14 – 16 lts of water for an ideal mix. Adjust the water content depending on the site conditions.
Do not over mix. Over mix can came air entrapment which could shorten pot life.
Do not over water material or Screed without perform as specified.
Screed can be applied in practical manners following the traditional phases required to produce cement based screeds.
If too much water issued this may result in shrinkage and cracking and a longer dying time.
Adjust compacting according to the final finish required.
Immediately after application and compacting of the screed adjust the surface using a metal flattener and seal the surfaces itself using a float.
The finish of the screed carried out by moistening. It with water and using a rotating steel disk very often in the
creation of a surface crust which is not very absorbent and will extend the screed drying time.
