1. Substrate
The substrate should be clean, free of dust, oily or loose materials etc. Very smooth surfaces should be treated with mild sand blasting or waterblasting, or carefully with chemical wash-up with 15% hydrochloric acid. Water leaks should be plugged with AQUAFIX rapid setting cement.
The surface should be dampened, before the application of DUROCRET-PENETRATE.
2. Application
DUROCRET is added into the exact recommended water quantity, under continuous stirring, until a homogenous mixture is formed. The material is applied using a trowel as usual.
After the end of application, the final surface must be treated for the next 2-3 days, so as for the waterproofing layer to remain slightly wet and harden properly.
Damping of the surface should be done by the time DURICRET-PENETRATE has started hardening in order to avoid the possibility of damages. Usually 2-3 times water spraying is enough per day. The applied surface should be protected from rain and frost.
