Uses:
As a quick drying sealer for furniture, partitions, doors, toys, shop fittings, cabinets, desks, wall units and most interior woodwork and hardboard. Spray apply 120-180 microns Wet Film Thickness to achieve 20-30 microns Dry Film Thickness. Overcoat after minimum 1 hour (sand 320). Overcoat with 262, 849/2 Clears.

Surface Preparation:
Wood � Sand and dust down
MDF � Sand faces with 150 grit, edges with 120 grit followed by 180 grit in the opposite direction.

Thinning and cleaning up:
Thinning not required, but 265 Floglos may be used. Clean gun and equipment with 265 Floglos.

Application:
Curtain coat
Spray � conventional, airless. Apply two double header coats at 50 psi (350 kPa) and allow to dry before sanding with 280 / 320 paper. Avoid spraying at high pressures, as this can cause bridging across the grain, with subsequent sink-back. Care must be taken to avoid heavy coats, as cold checking can occur at a later date if there is an excessive film build. MDF edges should be given an initial coat (thinned 15% with 265 Floglos) to improve sealing and reduce the tendency of edge cracking.

Drying:
- Dust free: 5-10 mins
- Tack free: 15-20 mins
- Print free: 20-30 mins
- Hard dry : 1 hour (can be force dried at 49-60 oC for 10-15 mins)
