Peeling Paint

Peeling paint is not a good thing, especially on the exterior of a house. It exposes the substrate, ie. wood or metal, underneath to the elements.

Proper prep work is essential to ensuring a long-lasting paint job.

Use of top-line paint is essential to a long-lasting paint job. To find more tips on painting the exterior of your home, take a look at this to set you on the right path.

Why would paint peel in the first place?

In Toronto, we have extremes of temperature between the winter and summer, this causes the substrate to expand and contract.

Metal especially expands and contracts with seasonal weather changes, therefore the paint system (both primer and top coat) must flex with the substrate during these expansions and contractions.

scraped and primed!

Acrylic Latex paint has flexibility built into it and therefore is generally the best paint to use on most exterior surfaces. Alkyd paint dries very hard, however, it doesn’t have a great deal of flexibility and can crack during the expansion and contraction cycles.

Moisture in the substrate.

Wood, being a tree, sucks up moisture and can retain moisture for long period of time. However, when the moisture is released this can cause a coating on the surface of the wood to peel and/or crack. Therefore, it’s imperative that the wood is dry before painting and that the wood is properly sealed from moisture penetration.

How do we know if the wood is dry enough to paint? We use a moisture meter which measures the moisture content in the wood, any reading less than 12% is in the safe zone. A few days of rain can really increase the moisture content of the wood, so it’s important to ensure the wood has adequate time to dry after the rain.

No primer has been used, or the wrong primer has been used.

Some primers perform better than others. We use high quality primers and different primers based on the surface we are applying the primer to. Wood requires a different primer than metal. Older homes with many layers of alkyd paint require a different primer than a newer home with only a few layers of paint.

When can you start exterior painting in Toronto?

When can you start exterior painting in Toronto?

toronto house painters, interior painting, exterior painting, wallpaper installationAs the signs of spring start showing up around us, I’m always asked: When do you start outside painting?

It depends on two factors which I’ll outline here


Before we can start painting outside the temperature must stay above at least 3 degrees Celsius overnight. The lower the temperature the longer the paint takes to fully cure (ie. dry all the way through).

Temperatures can be quite mild during the day in early spring however it can still be quite cold overnight, so this must be taken into consideration.

Always read the manufacturer’s recommendations listed on the paint can. Some paints require even warmer overnight temperatures before they can be used.

Metal surfaces, such as aluminium siding or wrought iron railings don’t retain water, so as long as no moisture is on the surface they are good to go. Before settling on your choice of aluminium though, it is important that you find the best sort for your project so that it has a finished look that you can be proud of. There are many different places that sell aluminium, such as Aluminium Warehouse (aluminiumwarehouse.co.uk/aluminium/angle) amongst others in your local area. If you are thinking about painting the aluminium afterwards, you may want to find some that is able to withhold moisture so you can finish your project at a quicker rate.

Wood, however, can retain moisture for many days. Therefore it’s important to check the moisture content of wood with a moisture meter. We look for under 20% moisture content, around 12% is ideal.

Horizontal surfaces, such as decks, tend to retain moisture more than vertical surfaces. Also, if a deck is close to the ground it tends to retain more moisture than a deck that is a few feet off the ground. The reason being is that a low deck traps moisture underneath and it can’t properly evaporate

When do we usually start exterior painting?

Typically we’ll start exterior painting at the beginning of May. Temperature is generally warm enough at that time of year and there will have been enough warm days in April to start to get the moisture content in the wood down to an acceptable level. This, of course, depends on what preparation needs to be carried out. If it has been a particularly bad winter, or there have been storms, a deck area might require deck repair service which can delay the painting process as some chemicals used may need time to cure.

As the exterior painting season draws to a close there is a problem:

Our phone is ringing off the hook from everyone that had planned to get some exterior painting done this year. Unfortunately we are fully booked for the next 4 weeks, which means we can’t take on any more exterior projects this year.

Many people had good intentions, but they just let time slip away on them… Of course, if you’re wanting the exterior of your home painted then make sure to look around on the internet for other companies that could complete your job requirements such as the likes of JD Hostetter or other exterior improvement services.

However, in every problem there is an opportunity:

If you book your exterior painting project for next spring CAM Painters will give you a painter for a day in December or January!

What’s the catch? There is no catch.

Here are the details:

The exterior project has to be at least $2000 before tax.

On the day that the painter for a day shows up you make a payment of $400 plus HST that gets credited to your exterior painting contract.

A painter for a day would be either one professionally trained, fully equipped painter for 8 hours or 2 professionally trained and fully equipped painters for 4 hours.

The painter for a day does not include paint and/or primer costs, it only includes the labour cost.

Need some ideas? Here’s what a painter can do in one day:

  • Paint a small powder room – ceiling, walls and trim
  • or paint a couple of accent walls
  • or paint all the walls in a bedroom or other similar sized room
  • or perhaps touch up some walls and/or trim that are a little worn looking

So schedule a quote now and make sure you don’t let another year of good intentions fly by!
