Exterior Paint: How to Make the Right Choice

How to choose the right type of paint with such a wide selection? The type of paint required will be chosen according to the material of the structure to be painted, and based on your personal taste. Then, just let your creativity be your guide!

Water-based and solvent-based paints

As for interior paint, exterior paint is divided into two types: water-based and solvent-based. In general, water-based paints are more user-friendly than their solvent-based counterparts. However, solvent-base paint has its benefits for certain applications.
Water-Based (Latex) Paint
  • Dries quickly
  • Clean-up requires only soap and water
  • Better colour retention
  • Breathable, keeping moisture from becoming trapped
  • Less odour
  • Non-flammable
  • Low VOCs
Solvent-Based (Oil or Alkyd) Paint
  • Easier to apply
  • Easier flow and levelling, giving a smoother finish with fewer roller or brush marks
  • Long lasting finish
  • Better adhesion to the surface

Pro tip

It should be noted that water-based (latex) paints will not adhere to oil-based paints. Oil-based paints can be applied over water-based paints, but do not apply water-based paints over oil-based paints unless specific preparatory work has been completed first.

Note: The same rule applies for primers.

A few application tips

Let's take a look at which products will help you achieve the desired result.

Paint, stain or sealer

Paint: Use paint for an opaque finish with unlimited colour options.

Stain: Use a stain for a semi-opaque (or opaque) finish. Available colours are not as diverse as paint's offering. Semi-opaque stains often enhance the underlying wood grain with a tinge of colour—a dark ebony, a warm gold, or a bright pink.

Sealer: Use a sealer to protect the structure. Sealers should be used for structures that will endure a lot of wear or exposure to harsh weather elements. Tinted sealers are available, so keep this in mind if you desire to change the structure's appearance as well as offer protection.

Decide on a finish

Matte: Does not clean well, but hides imperfections. Typically used for home sidings.

Satin: Finish is between that of matte and gloss. It hides imperfections well, yet is easier to clean than matte paint.

Gloss: Finish is shiny and durable, making it easy to clean. Highlights imperfections, so typically used on small applications that need to be frequently cleaned (such as trim and doors).

The surface must be contaminant-free and dry


Before launching into a painting project, it is important to first prepare the surface to allow the new paint or stain to adhere to the surface evenly and properly.
  • Remove dirt with trisodium phosphate (TSP).
  • Remove mould with a chlorine-based cleaner.
  • Remove old paint with a scraper and sandpaper. (If you get down to raw wood, be sure to apply primer before painting.)

Prime for a successful project


Primer plays a critical role in painting.
  • Protect both the paint and the wood by first applying a primer.
  • The primer will give the paint a smooth and even surface to adhere to, creating a watertight seal between the wood and the paint.
  • Sometimes dry wood can suck the paint in, creating an uneven or splotchy paint application.
  • By priming the wood first, you'll save yourself coats and coats of paint (therefore saving money and time).

Take the structure's measurements before heading to the store

And always purchase a little extra paint in case you need to apply touch-ups in the future.

Sunlight
Can blow debris onto your wet paint.
Colder temperatures (below 10°C) may prevent paint from drying.
Can cause the paint to dry too quickly, resulting in marks.

Humidity and rain can prevent paint from drying properly.
Direct sunlight can make it difficult to see what areas have been painted during the application.
Check paint label for recommendations regarding temperature ranges.

Paint large surfaces first

  • Paint from top to bottom.
  • If you are painting a house, follow this plan:
    1. Cornices
    2. Sidings (from top to bottom)
    3. Windows and doors
    4. Balconies and patios
    5. Shutters, storm windows and removable mosquito screens can be saved for painting in the garage on a rainy day.
Maintenance
  • Most paint applications require little to no maintenance. Check the product's label for specific information.
  • Typically, soap and water can be used to wash down soiled surfaces.

Pro tip

Wait for good weather to ensure a successful painting job. Be mindful of upcoming weather conditions.

Safety first

Take all necessary precautions to ensure you are carrying out your project in a safe manner.
  • Ladders: The use of ladders requires certain precautions. The base of the ladder should be set away from the wall, at a distance equivalent to one quarter of its height. If the top of the ladder is 12' off the ground, the foot of the ladder should be 3' away from the wall. And if at all possible, tie the foot to the side of the house.
  • Lead Paint: If you suspect the previous coat of paint contains lead, call your local professionals to ensure everyone's safety.
  • VOCs: Follow the paint manufacturer's recommendations on the warning label.

Accessories to make the job easier

Choose the right accessories for better results.

Paint Sprayer
A paint sprayer lets you apply your product faster and evenly even on irregular surfaces, such as shutters. It does not leave marks like brushes or rollers, so you get a mirror-like and professional finished result.

Brushes
Brushes are available in an array of shapes and sizes for different uses. By purchasing the correct brush for each application (i.e.: a narrow angular brush for corners and detailed work), you'll save yourself time while ultimately ending up with a nicer paint finish.
