Painting on Wooden Surface

The process of on wooden surface can be divided into three steps:

  • Pre- work
  • Surface preparation
  • Painting

Wooden Surface – Opaque Finishes

Surface Preparation

  • Previously painted wooden surfaces must be properly sanded to remove any dust or grease.
  • Apply wood primer by brush after thinning to given ratio by recommended thinner.
  • Allow it to dry for 6-8 hours, then apply putty or lambi.
  • Sand the applied putty with 180 no. sand paper and apply 2nd coat of wood primer.
  • Now the wooden surface is ready for painting with the top coat

Painting

  • For opaque finish, you can choose conventional enamels.
  • Apply wood primer by brush after thinning it to a given ratio with the recommended thinner.
  • Allow it to dry for 6-8 hours then apply putty or Lambi.
  • Sand the applied putty with 180 no. sand paper and apply second coat of wood primer.
  • Now the wooden surface is ready for painting with the top coat
  • Enamels are normally applied by brushing, although they can also be sprayed.
  • The drying time of enamels is longer; hence care must be taken to ensure a dust free environment while the paint film is drying.
  • Two coats of paint is sufficient in most cases, however if the earlier paint shade was significantly darker than the new shade an additional coat of paint is recommended.

Wooden Surface – Transparent Finishes

Surface Preparation

  • The Wooden Surface to be coated/painted must be seasoned (moisture level between 10-15%). It indicates proper level of moisture and treatment to prevent deformation in extreme hot/cold climate.
  • In case of new wood surface, first the surface has to be sanded with emery paper along the direction of the grains of the wood to remove the roughness of the wood.
  • This has to be followed by application of suitable wood filler. The purpose of the filler is to fill the grains and pores and it should not be used as putty. The excess filler must be removed by strokes along the grain pattern. After 30 minutes, the filler may be applied again if required. Allow 2 to 3 hours drying time.
  • Sand the filled surface with emery paper no. 320.
  • Staining with Wood Stains is optional. Do not use Wood Stains on exterior wooden surfaces.

Painting

  • For New Wood
  • Ensure that the surface to be coated is free from dust.
  • Choose any transparent coating for Clear Finish.
  • Two to three coats of finish coating application are recommended to achieve the best results in terms of gloss and decorative appeal.
  • Containers should be tightly closed after use.

For Pre-Polished Wood

  • Sand the surface along the grains with emery paper No. 180 followed by No. 320 to get a smooth uniform surface.
  • If staining is desired, completely remove the old finish. Wipe the surface free of loose dust.
  • Proceed with the finish paint coats as explained above.
