Surface Preparation

This being a topcoat, which is applied over, primer or intermediate coats, the surface should be free from oil, moisture, dust and dirt. Aged epoxy / PU coating should be roughened by emery paper grade 400 / 600 for better bonding.

Application Data :-

MIXING RATIO : Base: Hardener - As per our recommendations
APPLICATION : By Brush / By Conventional Spray / By Airless Spray
THINNER : Type 290
POT LIFE : 4 hours min at 30°C
OVERCOATING INTERVAL : MIN : 8 hours MAX : 24 hours
COMPATIBILITY : Can be applied over Epoxy and Polyurethane primers, intermediate coats and topcoats.

Application Method

Stir the Base part thoroughly. Mix the base and hardener as per our recommended ratio, by volume. Stir the mix thoroughly to attain homogeneity. Allow the mixture to stand still (maturation) for about 10-15 minutes to initiate the reaction. Add Thinner Type 290 into the mix, if required, depending on application method, and stir thoroughly for few minutes. Strain the paint through Nylon filter cloth of 400 mesh size and apply uniformly over the surface. All equipments used for above should be properly cleaned.

Application :-By Brush / By Conventional Spray / By Airless Spray

Generally no thinner is required for Brush application, however under adverse environmental conditions about 5% of thinner, by volume, can be added. Apply evenly in criss-cross manner and ensure the uniform application. Use quality brushes for paint application.

For Conventional Spray Application :-

Thinner : 290
Addition : 5 - 15%
Nozzle Orifice : 1.2 -1.4 mm
Nozzle Pressure : 40-70 p.s.i

For Airless Spray Application :-

Thinner : 290
Addition : Max 5%, if required.
Nozzle Orifice : 0.28 - 0.37 mm
Nozzle Pressure : : 1400-1800 p.s.i


1. Do not apply paint when temperature falls below 10°C or rises above 50°C and when Relative Humidity is above 85%. Do not apply during rain, fog or mist. Surface temperature must always be minimum of 3°C above Dew point.

2. Brushes and spray equipment should be cleaned with SAFFRO's recommended thinner otherwise equipment is liable to be damaged.

3. Products with different volume solids and for special applications like Flexible coating and anti fungal/anti bacterial versions are available on requests.

4. DFT variation can be obtained by change in application method / thinning ratio.

5. Shelf life indicated is minimum for this Product in sealed conditions and it is subject to re-inspection thereafter. Individual component is required to be stored in cool, dry and covered condition, away from heat and ignition.
