Two-component air-drying intermediate/primer surfacer coat.

Recommended Use :-

Recommended over putty / primer applied surfaces for better gloss retention and aesthetics in topcoats.

Physical Data :-

COLOUR : Grey, White
FINISH : Egg Shell to Matt
SPREADING RATE : 13.3 sq.mt / ltr at recommended DFT of 30 µ
FLASH POINT : Base : 23°C Hardener : 23°C
DRYING CHARACTERISTICS (At 30°C & 65% Relative Humidity) : SURFACE DRY : 20-30 minutes. HARD DRY : Overnight. FULL CURE : 7 Days

Surface Preparation

This being intermediate, it is applied either over primer. The surface should be free from moisture, oil and dust before application. In case of aged epoxy / PU coating or exceeded over coating, the surface should be sufficiently roughened prior to painting.

Application Data :-

MIXING RATIO : Base: Hardener ( As per our recommendation)
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 top coated by PU, epoxy, Chlorinated rubber and synthetic enamel paints. Compatible with Epoxy and zinc rich primers.

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. Add Thinner Type 290 into the mix, if required, depending on application method, and stir thoroughly for few minutes. Allow the mixture to stand still (maturation) for about 10 minutes to initiate the reaction. Strain the paint through Nylon filter cloth 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 crossed manner and ensure the uniform application. Use quality brushes for paint application.

For Conventional Spray Application :-

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

For Airless Spray Application :-

Thinner : Type 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. DFT variation can be obtained by change in application method / thinning ratio.

4. 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.
