So You Want To Paint Your Home?
How much paint will you need for your project?
•Calculate the area of each wall (height x width)
•Subtract the area of each window and door (height x width)
•Calculate the area of the ceiling (length x width)
•Painting over very dark colours will likely require a primer coat. To improve the hiding quality, you might want to have your primer tinted to match the finish coat.
Note: As a rule of thumb, calculate 37m2 (400 sq.ft.) for each four-liter (4 gal) can of paint.
Look for the manufacture date on the container and buy the most recent. Latex paints have a shorter shelf life.
Tools
Brushes and rollers are rated for the type of paint and for the application, e.g. ceilings, trims. Good quality brushes deliver less visible brush strokes.
Preparation
Proper preparation while it is the most labour intensive; it is the most important part of the job. You’ll spend about 80% of your project time on preparation and clean up.
1.Inspect the surfaces that you are going to paint. Look for popped drywall screwheads and replace or re-screw them. Remove any poster tape, or picture hooks or anything else protruding from the walls. Patch larger holes with glass fiber mesh (tape). Use a spackling or repair compound to fill these holes. Ensure each layer is dry before adding another layer. Smooth the material as much as possible to reduce the need for sanding.
2.WEAR A MASK when sanding the patches. Use #100 or #120 grit sandpaper if using wall repair compound and #220 grit for spackling compound.
3.Damp mop the floor and vacuum the whole room. For heavily soiled or greasy areas, or rooms where there were smokers, wash the surfaces with TSP (tri-sodium phosphate.) WEAR GLOVES and EYE PROTECTION when using TSP. Rinse with clean water. Ensure all surfaces are dry before painting.
4.Vacuuming may be the only cleaning option on textured walls or ceilings.
5.Prime all new drywall or plaster. Unpainted wood can be stained, painted or urethaned.
Covering crayon marks, water stains, knot holes. All these marks will bleed through most latex paints. Sparingly, apply a stain-blocking sealer before you paint. You may need to use shellac, alkyd or polyvinyl primer. Use only on affected areas. Because these products emit an odour, ensure that you direct a fan toward an open window and ventilate the area well.
Peeling paint must be scraped and sanded before painting. It is the result of moisture under the paint or using the wrong type of paint. Identify the cause of the moisture and correct the problem before repainting.
Mold appears on painted surfaces as dark spots. They are the result of moisture. Identify the cause of the moisture and correct the problem so that it does recur. Wash with soap and water and dry it thoroughly before painting.
Painting Pointers
•After patching, sand thoroughly
•Clean the surfaces after sanding
•Take a lint brush to a new roller before using
•Use paint at full strength, to ensure the paint resists washing and wear. Thinning the paint affects its durability.
•Paint with an open window when the temperature is above 10°C (50°F)
•Use vegetable oil to remove solvent-based paint from your skin
•Seal leftover solvents in a container and take to local toxic waste centre. DO NOT POUR SOLVENTS DOWN THE DRAIN.
