How To Prepare Exterior Walls For Painting?

For a great and smooth exterior finish, preparing the walls before painting is crucial. A great painting job melts the heart and even more so if its done by you. This is a relatively easy task that can be completed without much hassle by an expert DIYer. However if you lack the needed confidence to pull off your exterior wall painting preparation task, then hiring the services of a reliable professional who can guarantee the best result would be your best bet. In this step by step, we aim to take you through the steps involved in preparing exterior walls for painting.

Before you get started, you need to make sure you have the necessary tools in place. These includes a filler and filling knife, sandpaper, soap, sponge, wide paint brush, masking tape as well as drop sheets.

✓ Ensure a smooth surface with a filer and sanding. This includes removing and replacing any rotten or decaying timer, proper sanding as needed, scraping off of peeling areas with sanding and filling of cracking areas with the help of exterior grade filler. Once the above is completed, you can then proceed to filling any holes or cracks in your exterior surface with a top quality exterior filler ( the application should be done with a putty knife).

✓ Cleaning. With the help of a quality and soft brush, clear out the dirt and cobwebs on the exterior’s surface. Then wash the walls with a good detergent to remove any remaining dirt and grease. You can use a bristled brush and a high pressure cleaner to make the process easier.

✓ Mask the area. This involves using a top quality masking tape along the edges you do not wish to paint and pushing the tape’s edges down firmly in such a way to get straight edges.

How To Remove Old Exterior Paint

When the paint of your house is starting to peel, there’s the need to take a swift action. While some homeowners opt to cover it with vinyl siding or replace it with fibre cement siding, there’s no reason why you would want to hide the exterior of your house if it still looks great. When you don’t want to hide the beauty of your exterior, the only other option you’ve got is stripping or removing of the old paint. So how do you remove old exterior paint without much hassle? Let’s take a look!

✓ Propane blowtorch. Due to its affordability and effectiveness, this blowtorch has been one of the most popular means of removing old exterior paint amongst homeowners for quite some time. It makes use of high heat to soften the acrylic-latex paint which makes it easy to peel off with a putty knife. However, it can also be very risky to use as it’s always a dangerous game when it comes to open flames. What’s more? Applying an open flame to lead-based paint may release toxic lead fumes, therefore you’d have to be very careful if you wish to use this method.

✓ Electric sanders. Belt sanders are a great option to removing old exterior paint as they’re able to strip off the paint quickly. However, this must be done gently and carefully as you’d risk gouging the wood if you lay into the sander too hard. The problem with this method is also lead-based paint as the sander tends to convert everything to dust and direct them straight to your face, hair and lungs.

✓ Scrapping. This involves using a sharp, rigid putty knife or blade designed for painting scraping to strip the exterior paint. This method also involves dust but you’d have a better control over it than the sander.
