Preparation of base surface


Before starting work, ensure that no protective product such as pore sealant, lacquer or curing agent has been applied which might prevent the penetration of water.


To do this, apply a small quantity of water to the surface to be coloured at a number of points. If the water is absorbed rapidly, the surface is porous.


Conversely, if the water forms into droplets, your surface is not porous, and there is a product present which is preventing the penetration of water.


At this stage of the process, it is essential to identify what type of product has been applied.


If the surface is protected by acrylic lacquers or a concrete wax finish, we would recommend the use of a lacquer stripper, or the grinding of the surface concerned.


Application of Harmony preparatory agent


Application must be completed within a temperature range of 5° - 25°.

Coverage : 1 litre/10 m2, depending upon surface porosity.


1. Harmony preparatory agent should be applied without dilution.


2. Spray Harmony preparatory agent in a highly-controlled directional jet, in order to prevent any inhalation of the mist generated by vaporization.


3. Leave the product to work for a few minutes, then wash with Harmony neutral cleaning agent.


4. Rinse with water and leave to dry for 24 hours.
