Surface preparation

The wooden surface must be dry, carefully sanded and cleaned from dust and other impurities.


Stir thoroughly both before use and between the applications, but be careful not to let air into the product. Apply first a thin coat of HELO AQUA 5 varnish by brush and let it dry for at least one hour. Sand the surface and remove all sanding dust carefully. Apply a second coat of varnish and let dry for about 3 hours before applying the third coat, if needed. Untreated wooden plank floors: Prime with 15 % diluted HELO AQUA 80 using brush or trowel. Intersand, if necessary, and finish with 2-3 coats of 10 % diluted HELO AQUA 5 using brush or trowel. Spread out the varnish in the direction of the pattern and the grain of the wood. Previously varnished plank floors: It is recommended to sand the surface to bare wood and follow the instructions for untreated plank floors. If the old varnish is in good condition HELO AQUA 5 can be applied after intersanding (sandpaper n:o 100-150) to the surface according to above mentioned instructions. In this case the adhesion needs to be tested on a small area.
