POWDER ADMIXTURE – WATERPROOFING for cement mix – concrete, grout, render, stucco or mortar.
TECON-DRYMIX is a dry powder admixture for cement based mixture and composition, providing excellent waterproofing and reducing water absorption of the composed cement mix. Composed from processed silica & resin mixture, TECON-DRYMIX comes with small micron of particle size, water soluble with ease and chemically reacts with cement structures upon mixing.
TECON-DRYMIX does not work as a sealant, after chemically react with cement mixture, the cured cement surface remains breathable where moisture trapped behind the coated surface still able to evaporate through the pores to the enviroment, this is extremely important by releasing the inner pressure of the substrate, minimizing cracking of the surface.
Mix TECON-DRYMIX between 0.2% to 1.0% of the total cement mix weight. E.g. mixing a cement render of 50KG (12.5KG of cement + 37.5KG of sand) required 250Gram (0.5%) of SEALOC-ADMIX.
Suggested cement mix ratio:
|Concrete||1||1.5||3||0.25% – 0.5%|
|Mortar||1||4||–||0.5% – 0.75%|
|Render||1||3||–||0.25% – 0.5%|
A proper surface preparation helps to ensure maximum performance and durability of our coatings. The surface must be completely clean from grimes, dirts, dust & grease.
AS WATERPROOFING ADDITIVE : During the mixture of cement, add in cement then follow by TECON-DRYMIX, lastly mix in sand/aggregrate. Advisable 20% to 30% of total water mixture to be used during the stir mix.
If there is more than 200 KG per mix, e.g. 1000KG total cement mix, it is advisable to seperate the mixture into 5 portion consisting only 200KG mix per time to provide consistent spread of TECON-DRYMIX.
|Coverage :||200KG per 1KG mix (0.5%)|
|Shelf Life :||24 months|
