APPLICATION CONDITIONS:
Ambient temperature: minimum 10° C (50°F) – Optimal between 12° and 25°C (54° and 77°F).
Relative humidity: maximum 80 %
Dew point > 3°C (5°F)
The screed may not contain more than 4% humidity.
APPLICATION MEANS:
Brush, roller, or airless-spraying equipment (nozzle opening: 021-023)
PREPARATION OF THE SUBSTRATE:
The substrate must be dry, degreased and dust-free.
Smooth screeds must be treated beforehand, different options are possible:
- Sand the surface to obtain roughness
- Lightly etch the surface with an acidic solution
- Apply a layer of RD-Multiprim.
Repairs on concrete should be made using RD-Cement Filler.
MIXING RATIO:
By weight: Component A: 860 g - Component B: 140 g
By volume: 4,8 : 1
The hardener and the base must be mixed scrupulously respecting the indicated ratio. Do not leave product in the bottom of the hardener packaging. A bad mixture can cause damage, such as bubbles, poor hardening, matt and weaker spots.
Mixing:
• Mix mechanically long enough (for +/- 3 minutes for 15 kg of product) the two components until a uniform mass of one colour is obtained.
• After mixing, let the mixture rest for about 5 minutes to allow the product to cool and eliminate the formation of air bubbles.
POT-LIFE:
2 hours at 20°C
DILUTION:
Dilute the first coat by maximum 10% with water when applied as primer on a porous substrate
DRYING TIME (20°C - 68°F):
Touch dry: after 8 hours
Recoatable:
• at 10 ° C / 50 ° F, at least 24 hours and 48 hours maximum,
• at 20 ° C / 68 ° F, at least 12 hours and 48 hours maximum.
In the event of a longer overcoating time, it will be imperative to sand the first layer to ensure optimal adhesion of the next layer.
Final hardness after 7 days
RD-Hydropox needs 72 hours at 20° C/68° F to obtain maximum mechanical properties. For full chemical resistant properties, 7 days are required at a temperature of 20 ° C/68° F.
This means that during this period, no liquids, including water, should come in contact with the coating.
CLEANING OF TOOLS:
Water
SPECIFICITIES:
Mix well before use.
