Painting Tips

Tools for Painting Works

1. Brush

  • Brushes made of hog or ox bristle should be used for alkyd paint.
  • Blend polyester and nylon with animal bristle can be used for all purposes.
  • A quality brush has flagged bristles and chiseled end for precise edging. A cheaper brush will have a blunt end, unflagged bristles.

2. Roller

  • A roller should have a handle molded to fit your hand and should be well balanced when hold. There should be a threaded end at your handle to attach an extension handle for painting ceiling and high walls.
  • Roller covers are available in a wide variety of nap lengths. Most jobs can be done with 3/8” nap.
  • Synthetic roller covers are good with most paints especially latex paint. Choose a medium-priced synthetic roller cover to avoid fiber shedding onto painted surfaces.
  • Wool or mohair roller covers give an even finish with alkyd paint.

3. Air Less Spray Gun

  • Cost effectiveness for larger areas painting, uneven surfaces and faster job.
  • Do not need compressor as per conventional spray gun.
  • Need a skilled sprayer to avoid overspray and paint wastage.
  • Choose a right tip size according to instrument manual and paint manufacturing manual for ease of handling and to achieve right thickness.
  • Good for thicker paint film requirement.

4. Conventional Spray Gun

  • Need air compressor to run the equipment (compressed air help in paint atomization).
  • Good for thin paint film requirement and lower viscosity paint.
How to Use a Paint Brush
  • Transfer some paint from the can into a small bucket (to help you move around the room easier).
  • Double-check the types of paintbrush. Use synthetic bristle brush for water based and hog or ox bristle for alkyd based.
  • Don’t overload your paintbrush. Dip the bristles only about half into the paint and tap on the side of the paintbrush.
  • Begin with horizontal strokes in back and forth manner and from dry areas back to wet areas to avoid lap marks.
  • Smoothen the paint evenly by using vertical strokes. Feather the edges by brushing lightly with the tip of your brush.
  • To draw a straight line along the edges where a wall meets the ceiling or other surface (where you do not want it to be painted), hold the brush at a slight angle and stroke slowly to move the brush slightly away from your edges as you go.
How to Paint with Paint Roller
1 Fill the paint tray reservoir. Dip the roller fully into the reservoir to load with paint. Lift the roller from the paint reservoir and roll it back and forth on the texture ramp to distribute the paint evenly onto the roller. The roller should be soaked but not dripping when lifted from the paint pan.
2 With the loaded roller, make a diagonal sweep (1) about 4’ long on the surface. Use slow stroke to avoid spattering and roll upward on the first stoke to avoid spilling.
3 Draw the roller straight down (2) from top of the diagonal sweep. Shift the roller to the beginning of the diagonal and roll up (3).
4 Distribute paint over the rest of the section with horizontal back and forth strokes.
5 Smoothen the area by lightly drawing the roller vertically from the top to bottom of the painted area. Lift the roller and return to the top of the area after each stroke.

 

Painting Ceilings and Walls
1 Painting Ceilings

  • Use a narrow brush to cut in 3” strips of paint along the ceiling section. Paint ceiling using a roller handle extension. Start at the corner furthest from the entry door.
  • Paint the small section 3 x 3 feet in diagonal (zigzag) strokes. Distribute it evenly with back and forth strokes. Feather the edges by lifting the roller at the end of each sweep.
2 Painting Walls

  • Using a narrow brush, cut in a 2 “ strips along the edges (where the wall meets the ceiling or wood work).
  • Start with upper right hand corner if you are right handed, or start with the upper left hand corner if you are left handed to avoid accidental leaning on to the wet wall.
  • Paint wall in 2’ x 4’ section. Make the initial diagonal stroke from the bottom of the section (zigzag) to avoid paint from dripping. (Follow the roller painting methods).
  • Next cut in and roll the section underneath (2). Continue painting adjacent wall sections, cutting in and rolling the top sections before the bottom sections. Roll all finish strokes towards the floor.
Factors Affecting Colors

1. Reflection from Background Colour

  • If the background colour is stronger than the small piece of sample, the small sample tends to pick up the reflectance from the background colour (e.g. Red in background, sample in shade of white, then the sample tends to appear white with reddish tone).

2. Different Light Source

  • Different light sources with different wavelengths will give you different colour (e.g. Colour judge under natural light source such as day light when compared to the same colour judged under artificial light, incandescent light or even fluorescent light, will be very different.

3. Different Gloss Level

  • Higher gloss level paint will look darker than the lower gloss level paint. Therefore, the same colour will appear to be slightly different over the range of products produced in differing gloss levels.

4. Different Thickness (Semi-Transparent Colour)

  • Bright colours with organic pigment content will give you a poor hiding power compared to colours produced with natural earth pigments. Hence, the thickness of the paint film can affect the colour. The thicker it is, the darker/stronger the colour will be.

5. Different Application Methods

  • There is a light variation in colour if shade card is compared to actual paint film. This is due to different application methods. Shade card is printing process and coating is applied using brush, roller or spray gun. Therefore, there is no 100% match to different application methods.

6. Tips

  • It is always wise to keep at least a small amount of every paint colour and finishing products for touch up purposes. This is to avoid cumbersome problems that may arise during touch up especially those colour or product which might not be available in small quantity.
  • Paint deep pattern surfaces with a stiff-bristled brush to help in penetration.

Where the surface has been previously painted with several coating of cement base paint or emulsion paint which has been adulterated with lime or extenders, thus an absorbent, soft and “chalky” surface is usually apparent. Under such conditions remove as much of the previous coatings as possible by scraping or high pressure water jet. If all the old paint can be removed proceed as far new work otherwise a sealer coat to blind the surface is necessary.
