Harmony Preparatory

Description

Harmony Preparatory Agent is used to prepare surfaces for the application of Harmony Patina Concrete or Harmony Acid Stain by opening up the pores in the base material.

It can also be used as a detergent to clean all concrete surfaces.

Caution: When smoothing P3 or P4, or in the case of a weak / absent porosity of the support, this product can not improve absorbency.

Characteristics

Type: Detergent

Packaging: 1 l, 5 l, 20 l

Dosage: 1 litre = 10 m2, undiluted and depending upon surface porosity

Storage: 12 months in unopened original packaging, stored in a dry and frost-free location.

Tools & Cleaning

Viton seal sprayer, mask, gloves and protective goggles.

Clean tools in water after use.

Preparation

Before starting, 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 grinding of the surface concerned.

Application

Application must be completed within a temperature range of 10°C - 25°C.

1. Harmony Preparatory Agent should be applied without dilution. Coverage: 1 litre/10 m2, depending upon surface porosity.

2. Spray Harmony Preparatory Agent in a highly-controlled directional jet, in order to prevent any inhalation of the mist generated by vaporisation.

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.
