Painting both the inside and exterior walls may do wonders for giving your house a new, bright look. However, a little wall prep for painting can go a long way toward achieving a perfect finish that will last before you drop that brush into the paint. Washing walls, wall cleaning, and sanding walls before painting are all part of wall preparation before painting.

Steps to Prepare Your Home for Exterior Paint     


We’ll walk you through the steps to get your house ready for painting, both inside and out.

– Ensure a weather-friendly day

Check the weather forecast before starting your painting adventure. It will be easier for the paint to adhere and dry uniformly if you paint on a dry day with moderate temperatures.

  • Prepare and Clean the Area

Preparing the exterior wall for painting is important! The best way to prep walls for painting is to clean the external walls to get rid of any mildew, dust, and filth. Years of dirt can be removed with the use of water and a little detergent, leaving a clean surface for the best paint adherence.

  • Scrape the old paint

Any loose or peeling paint should be scraped off using a paint scraper. You can avoid an uneven finish that is caused by painting over old, flaking paint by scraping. Areas where the previous paint is lifting or chipping deserve extra care.

– Sand the Exterior Walls

Sand the external walls to remove any rough edges after scraping. This process not only smooths the surface but also aids in the fresh paint’s better adhesion. Don’t forget to use the proper safety equipment when doing this.

– Caulk gaps, patch holes, and replace wood rot

Search for holes, cracks, and gaps in the outer walls. Gaps should be caulked, and the right filler should be used for holes. Replace any areas of wood that have rotted before continuing, if you find any. A durable finish requires proper wall preparation before painting.

  • Prime Stains and Bare Spots

Apply an exterior primer to areas where there are stains or exposed bare parts. By priming the surface, any imperfections are covered, and the paint adheres uniformly. Before moving on to the following step, let the primer completely dry.

  • Paint It!

It’s time to start painting. Select a top-notch exterior paint that is appropriate for your climate. Using a paintbrush or roller, distribute the paint uniformly. For a finished product with a professional appearance, adhere to the manufacturer’s recommendations for drying periods between coats.

Steps to Prepare Your Home for Interior Paint

Before diving into interior painting, thorough wall preparation is essential. Follow these steps for preparing interior walls for painting to ensure a flawless finish:

  • Wall Cleaning

A simple way is to start by washing walls and wall cleaning. Grease, filth, and dust can prevent paint from sticking. To ensure a spotless surface, wash the walls with a light detergent solution.

  • Old Paint Removal

Use a paint scraper to carefully remove any old, peeling paint from the walls. Sanding walls before painting will create a smooth canvas for the new paint.

  • Repair the damaged areas

Check the walls for any dents, holes, or cracks. Sand down any remaining speckling compound to create a smooth surface after filling up the defects.

  • Use lining paper for any cracks

Take into account the use of lining paper for larger fissures. This gives the painted surface a uniform polish and keeps cracks from reappearing.

  • Prime your walls

Prior to painting a wall, priming is an essential step. To establish a smooth surface, increase paint adhesion, and boost colour brightness, use an interior primer.

    If we don’t clean our walls, I’m sure that dirt and dust will make the coat of paint look a lot worse. This is why I think we should try and find an effective way to wash away all of that dirt first before we apply a new coat. I’ll make sure this is something we do by washing our house first before we hire a house painter in the area.
