Application
Surface preparation
- A clean, sound structure is required. Remove all oils,
stains and imperfections.
- It may be necessary to high pressure clean @ min. 120 bar
pressure and thoroughly rinse the surface and/or skim the
substrate with Lanko Rep FC.
- The substrate must be dampened prior to application, leave
no standing water. Do not dampen between coats; remove
any condensation water with a clean cloth.
- No additional priming is required on sound cement
based substrates.
- Apply the product with a painter's block brush or quality
mohair roller - can be spray applied.
- Apply two coats of Hydroflex, waiting for the first coat to
set-up before applying the second, so as not to draw off the
first; between 4 - 24 hours is suitable.
- Each coat should be applied at a rate of 1,5 kg/m2 minimum.
- Apply the first coat in a vertical motion and the second
horizontally in order to effectively eliminate the possibility
of pinholes.
- The total thickness of the coating should not exceed 2 mm
in thickness.
- The final coat can be smoothened using a putty knife or
a steel trowel.
- Mortar must be used within 20 minutes of preparation (25°C)
