5 Ways to Prepare Your Interior Walls for Painting

Are you planning on doing some home interior painting? Before you pick up the paint roller, make sure that your walls are completely prepared and ready for a new paint job. Spending a bit of extra time preparing your walls will ensure that you see much better results and avoid any potential problems along the way. If you’d rather leave the preparation up to the professionals, the team at SG Coatings are available to help. SG Coatings has years of experience working on home interior painting services for all types of homes. Our professional home interior painters will only use high-quality paints. They will also ensure that the surface preparation is completed with care from the start to the finish. However, if DIY is your cup of tea, we’ve listed some important tips below. To help you ensure that your walls are primed and ready, we discuss 5 ways to prepare your interior walls for painting.

1 – Prepare your workspace

It’s no surprise that painting can potentially get a little messy. For this reason it’s important to cover the floor with canvas drop sheets in order to prevent any spills. You will also want to move any furniture out of the way to avoid any unwanted paint jobs. If the furniture is too difficult to move, you can cover the furniture with plastic drop sheets. You’ll also want to ensure that your walls are completely free of any nails, pins or anything else that may have been placed onto it. You’ll also want to switch off the circuit breakers to the room that you’re painting and remove the cover plates from the power outlets and switches. Cover the outlets with tape to ensure that they stay free from paint. Apply professional painter’s tape to the edges of the walls to keep your paint job clean and tidy. This will prevent splattering and will ensure you have smooth, straight lines around the skirting boards and the corners of your room. 

2 – Repair any holes

Once you have selected a wall to paint, the first thing you should do is check the wall for any wear and tear or damage. If you notice any small holes or divots in the wall, you can patch them up with spackling paste. This is essentially a thick white paste that will fill the hole and sit flush with the rest of the wall. If there are any larger holes in the wall, you may need to use a patch and joint compound to repair the plaster. This is a self-adhesive patch which is placed over the hole and covered over with more spackling paste. If you’re unsure how to tackle these issues, contact our professional painting team here for some assistance.

3 – Sand the walls

The next step after applying spackling paste and letting it dry is to sand the walls back using sandpaper. If you’re only painting a small area, you may only need a small piece of sandpaper or a sanding block. For larger areas you can attach a sanding block to a long pole for more coverage. Sanding the walls back will remove any old flakey paint which has been left behind. It will also even out the surface of the wall so that the paint can adhere to it correctly. It’s important to sand the walls back when home interior painting, as an uneven surface could spell disaster.

4 – Wash the walls

It’s extremely important to wash your walls before applying any paint. Painting on a dirty wall is guaranteed to cause some problems. It can cause the paint to be unable to adhere to the wall. Take some warm soapy water and wash the walls with a sponge or a cloth. This will remove any leftover dust or dirt from the walls, creating a perfect clean canvas to begin painting on. Ensure that the walls have dried completely before you begin to apply your paint.

5 – Prime the walls

The final step to preparing your walls is to prime them. Primer allows the paint to adhere to the wall correctly, giving it a perfect finish for a professional paint job. Firstly, make sure that the roller and brush you are using to apply the primer is damp so that it can be absorbed. Start with a brush at the corners of the walls, making sure to cover the areas that the roller can’t reach. After the corners are primed, roll the rest of the walls in consistent 3 ft sections in a V or W pattern. Make sure to move from one side to another, overlapping to ensure an even coat. If you’d prefer to let a professional painting team apply the primer, you can contact us here for a free quote.

If you’re looking for a professional painter to prepare your walls for home interior painting, look no further than the team at SG coatings. From repairing holes to priming your surfaces, our professional painting team will ensure that your paint job is taken care of from start to finish. Our painters have years of experience in the industry, guaranteeing a hassle-free painting process. For a high-quality paint job that will stand the test of time, contact SG Coatings.

We had SG Coatings paint our office buildings recently, and I genuinely can’t fault them. This was a commercial job, and from start to finish, their team was professional, easy to deal with, and incredibly efficient. They were respectful of our workspace, worked around our schedule with no fuss, and the quality of the finish is spot on. You can tell they really care about the end result and take pride in what they do. Great service, great people – wouldn’t hesitate to recommend them and we’ll definitely be getting them back for future work.

We recently used SG Coatings to paint the exterior of our home, and we couldn't be happier with the results. From start to finish, the experience was smooth, professional, and stress-free. They were punctual, courteous, and thorough. Communication was excellent throughout the process, and the project was completed on time and within budget. We appreciated the care Sophie and her team took to protect our landscaping and clean up afterward. We highly recommend SG Coatings to anyone looking for quality, reliable exterior painting work. We’ll definitely be using them again in the future!

Sophie and her crew painted sections of our property, along with fixing areas another painter painted poorly. They were always on time, friendly, knowledgeable and efficient. Nothing was too much. After having experienced poor work it was fantastic to see a team work well together and their work was exceptional. We wouldn’t hesitate to recommend them, the prices were fair and the work was fantastic.

Sophie and her team have done an incredible job with painting the exterior of our house. It was badly needing a refresh and update. With Sophie’s recommendation of a colour consultant we have been extremely happy with the result (Winter terrace with black trim). The team did the most amazing job in somewhat trying weather conditions on a couple of days. The whole SG team were very professional, hardworking and punctual from day 1. We both just love the final outcome and would highly recommend SG Coatings. Thank you to all for such a great job. Attached before and after photos.

Just had Sophie and her team do some painting repairs inside and out, recoat our deck and restain our fences. Easy five stars. Everyone was on time, polite and proficient. They listened when we had some changes to make and everything felt like it was doable. The quote process with Sophie was clear, detailed and the price was good. Easy, straightforward and the work was high quality. If you’re on the Mornington Peninsula keep it local and keep it quality.
