Preparation
Surfaces must be clean, free of resins, oil, old weathered coatings and dust. Sand surface smooth using the right sandpaper for the task. Surface should not be cleaned with water before varnish application.
► New wood:
Apply 1-3 coats of POLACRYL 301. Allow to dry completely, sand lightly, remove sanding residue with a rag and apply 2-3 coats of POLACRYL 345, thinned with W.S. by 5-20%. If POLACRYL 301 is not used, thin POLACRYL 345 with W.S. by 40-50% for the 2 first coats. Allow to dry, sand and apply 2-3 final coats after thinning it with W.S. by 5-20%.
► Old wood:
Sand and remove sanding residue with a rag. Use POLACRYL 305 to fill large gaps and cracks. Apply 2-3 coats of POLACRYL 301 depending on the absorbency of the wood. Apply 2-3 coats of POLACRYL 345 (thinned by 5-20%).
► Poor quality wood:
Remove old paints down to bare wood. Sand and remove sanding residue with a rag. Then, follow the instructions for new wood.
► Teak & Greasy Wood:
Clean the surface with acetone or xylene. Allow to dry. Apply 2 coats of POLACRYL 301 (apply the next coat when the varnish is slightly sticky to the touch). Allow to dry, sand and clean thoroughly. Apply 3-4 coats of POLACRYL 345 (thinned by 5-20%) depending on the needs of the wood.
Use
► Surface humidity must not be over 18%.
► Do not apply when ambient temperature and wood temperature is below 10°C and when relative humidity is high.
► Shake or stir well before use.
► Sand surface smooth with the right sandpaper for the task before painting.
Drying out - Coverage
Drying times are dependent on ambient temperature and film thickness.
Touch dry: 2-3 hours
