Prepping Tips for Applying a New Coat of Paint

In order for a paint application to last, surface preparation is key. Even if you use top quality paint on a surface that’s not prepped for a new layer of paint you won’t get the desired results. Whether you are requesting the services of a professional or planning to apply a new coat of paint yourself, it’s important to follow these prepping tips:

Before prepping the surface, it would help to diagnose common paint problems. Assess the surface for signs of poor prepping on a previous instance. Look for excess moisture and alligatoring paint which refers to layer caused by poor paint application in the past.

Other problems could include dark mildew spots and chalking. Prevent the same from happening by thoroughly prepping the surface, scraping off the problem areas, increasing airflow to avoid mildew build-up and channeling water away with gutters and downspouts.

- Pressure wash the surface to remove dirt. Paint won’t stick to a surface that’s dusty or dirty and you’ll end up with an uneven, flaky surface.

- Have a sharp scraper on hand to scrape away old, flaking paint. Make sure the surface is dry when following this step. Scrape in the direction of the grain to prevent damage to the surface.

- Fill holes and gouges before priming the surface. Small blemishes can be treated with an exterior spackling compound and cracks with caulk.

- Prime all unpainted surface before application of paint.

- When you want to paint a surface with a new colour, you need to firstly prep the wall with a white basecoat.

- In some instances, you might need a sanding tool to get rid of sharp edges and uneven platforms.

- Protect adjacent surfaces by taping them off with masking tape.
