1. Start with an Exterior House Wash
It is important that you spend some time washing the dirt and grime off of the outside of your house before you start DIY painting. If the exterior surface of your house is free of paint-repelling soil, the primer and paint will adhere better. Creating a long-lasting appearance of your home.
Most of the time, a simple wash with a hose, a pump sprayer and a scrub brush is sufficient. But if you decide that you would prefer a professional to help you, a power washer in the hands of a professional can provide a superior clean.
We don’t recommend that you try to use a power washer on your own unless you are very familiar with it because it can cause damage to house wood siding and house trim if used incorrectly.
2. Prepare Your House For Painting
Before you paint the exterior of your house in Toronto, you should scrape off any bubbling or blistering paint that could cause future problems for your DIY painting project.
Note: Beware of lead paint! Some houses that were built before 1978 have paint on them that may contain traces of lead paint. Exposure to lead paint can cause anemia, learning disabilities in children, and damage to the brain and nervous system. When working on the exterior of your historic home (older than 1960) be sure that you observe the proper safety measures, including:
3. Sand the Area Where You Would Like to Paint
The goal when DIY painting the exterior of your house in Toronto is to have the cleanest and most beautiful exterior you can. Sanding will help by smoothing out any bumps or lumps that can look strange under a fresh coat (or 2) of paint. Recommendations for sanders:
- Random Orbit Sander
- Pad sander
4. Patch and Fill Holes
The goal here is to repair any damage that could worsen over time, requiring an unnecessary future DIY painting of your home.
You can remedy little holes in siding with an exterior patching substance, readily available in a premixed type. In a dry powder type, you have to mix it with water. Ensure durability by looking at the packages that state that the patching compound is for exterior use.
To patch holes in the siding of any kind, simply clean the hole that you plan to fill with the compound. Smoothen the area you wish to spot with 80-grit sandpaper for a better result. After doing so, fill the space with the exterior patching compound. Apply the compound to the hole in one direction. Smooth it in a vertical stroke to level with the initial surface area. Then wait for the compound to solidify, and after that, smooth it out. The mixture diminishes, so another coat might be required. Ensure to eliminate the dust from sanding the compound prior to another coat.
This way, painting the exterior house with a roller would be easy, as there would be no debris sticking to the rollers after all the patching and sealing.
On the contrary,
Remove any decaying wood with a sculpt to repair large fractures and damaged trim to avoid unsightly painted house exterior visualizers. Be sure that you repair any rotten wood, fix any dents and replace damaged pieces of your home that might get worse in the future.
Use a two-part polyester-based substance to make the repair work successful, perfect for house painting DIY as well. Two-part fillers come with a thick paste base and a little tube of hardener substance. Mix the hardener substance with the paste according to the product’s manual. The filler will be set within five minutes, so better mix only what you can use immediately and make sure to clean your tools right away after use. This is also to avoid catastrophe on painting outside of house colours by not knowing this matter.
Make use of a putty knife to apply the compound to the problem area and level it with the surface before painting the exterior walls for the first time. This filler doesn’t shrink when painting over old exterior paint as much as premixed exterior fillers do. However, you may still need to use several coats to fill a larger hole. After the filler solidifies, it can now be subjected to drilling and sanding.
Two-part polyester-resin fillers
It can be used for aluminum siding using the same method. However, before applying the filler, the exterior wall painting process must be followed step by step, and how to seal a house before painting must be followed first. Thus, drill numerous 1/8-inch-diameter holes in the spot. When you use the substance, it locks into the holes for a better bond and solidification. You can also cover the damage with a new piece of siding. To do so, cut the top flange off in order for the patch to fit under the course above. And embeds it in adhesive caulk along the top and side edges.
5. Caulk and Seal (Any Windows or Openings to Prevent Air and Water From Leaking In)
This may be the most important part of the Exterior House Painting Process. It’s important to have a well-maintained, beautified, non-rotting wood house, but it’s just as important to make sure the windows, cracks, and openings aren’t leaking air or letting in water which can ruin the interior of your house.
Depending on the severity of the deterioration, you can even resort to heavy-duty, professional-grade, industrial caulking. See the exterior caulking page. Painting the exterior of your Toronto home is a lot of work, can be very messy if you aren’t careful, and potentially dangerous as well if dealing with ladders. It is important to consider protecting your landscaping and cars when doing DIY painting. You don’t want to get paint all over your bushes (or your brand-new car!).
Most hardware stores and paint stores carry plastic paint sheets that you can use to protect any surface from getting covered in paint.
While professional painters sometimes use paint sprayers for external house painting (because it is faster and may provide a more even appearance than by hand), it can be very messy in the hands of a novice sprayer. You may find that without proper training, paint sprayers can cause more damage than good, so leave them to the professionals if possible.
