Blocking: Undesirable sticking together of two painted
surfaces when pressed together (e.g., a door sticking to
the jamb).
Possible Cause:
Not allowing sufficient dry time for the coating before
closing doors or windows.
Use of low quality semi gloss or gloss paints.
Solution:
Use top quality semi gloss or gloss acrylic latex paint.
Low quality latex paints can have poor block resistance,
especially in warm, damp conditions.
Follow paint label instructions regarding dry times.
Acrylic latex paints generally have better early block
resistance than vinyl latex paints, or alkyd or oil-based
paints; however, alkyds develop superior block resistance
over time. Application of talcum powder can relieve
persistent blocking. |

Painting tips & tricks
Helpful Tip
When taking a break, don't leave your brushes or rollers sitting in paint. Cover
trays with a damp rag.
Giving old wood a fresh look
Exterior wood siding can be painted, or stripped and
painted. Strip paint using a torch by burning the old paint
and scraping it lightly being careful not to damage the
wood. Clean the surface with trisodium phosphate (TSP),
which you can find in the paint department of your local
home renovation centre. Repair siding where needed and
caulk. If you are repainting in the same colour, apply the
finishing coat after the wood is dry. If you are changing
colours, apply a primer coat followed by the new colour,
using exterior paint (an oil based primer will be necessary
if going from oil to latex). Avoid painting in full sun, at
sunset, in the early morning, in the rain or in the wind. To
keep bugs from sticking to the fresh paint, simply add two
tablespoons of citronella to the paint.
Finishing product: paint, stain, varnish, etc.
Different customers have different needs. No product meets
every need. To select the appropriate product, start by
identifying your needs based on the following specific
criteria in order to create a “funnel” leading to your ideal
product. The product selection process is simple, effective
and based on eight product selection criteria: function,
environment, surface, use, composition, appearance, colour
and quality.
Masking knots before painting
Knots in finished wood will appear sooner or later after
painting. Before painting, seal the knots with a lacquer. It
is the only liquid sealant that will efficiently seal in
knot resin, without discoloring the finishing paint. |
