Surface Preparation and Painting Tips | | | | The preparation of a surface is 90 percent of painting job. Even the highest quality paint won’t adhere properly if the underlying surface is not prepared properly. Good surface preparation means clean and smooth surface.
Tips for Surface Preparation
- Allow newly plastered surface to mature for a period of at least 6 months before painting.
- Rectify existing surface problems such as dampness, cracks etc. before actual painting process.
- Check for hand prints, greasy fingerprints, algae as well as dirt and stained marks.
- Use a scraper, putty knife or scrub brush to remove any dirt, grease, rust, or flaking.
- Fill in the holes, cracks and joints with plaster.
- Clean and dry the surface.
- Make sure the area to be painted is well ventilated as well as free of dust.
- As far as possible, don’t paint under much humid conditions.

Do before starting painting work
-
Remove materials such as light fixtures, curtains and their rods etc. from the room to protect them paint splashes. The materials which cannot be removed out should be placed at the center and be covered with a canvas or plastic sheet.
-
Place a large bin with a plastic bag to gather debris or paint splashes. A dirty work place is not only unsafe but can slow the process of painting also. Also make use of canvas to cover the floor to avoid paint splashes.
-
Insert nails and hooks for pictures. Fill the holes made by nails with plaster and sand before painting again.
-
Use painter’s tape to cover up the area that you do not want to paint. Also do the same for doors, windows and ceilings that you can not remove.
