Why Is It Important to Remove Old Paint From Walls Before Re-Painting?

Although it’s popular to simply go overtop of your existing paint with a fresh coat, sometimes this is just not possible. If you have an older home, you can’t be certain what kind of paint was used on your walls. In many instances before the 1980s, the paint will contain lead, a substance that can be harmful.

How to Remove Paint From Walls in 5 Steps


How to Remove Paint From Walls in 5 Steps


1. Prepare and Protect

Before you tackle the paint on your walls, make sure to set up the area you will be working in and around. This is necessary to protect your skirting boards and flooring. Paint removal can be messy work, so be sure to find enough drop cloths to cover your floors. This will catch most of the paint chips and act as a barrier. 

You may also want to apply tape against the edge of your skirting boards if you are using the chemical cleaner option so the paint thinner won’t drip and damage your finishes. 


2. Decide on Your Method

To remove paint from your walls you can choose either working by hand to remove paint or using a chemical paint stripper. Both are valid ways to remove your paint but one may be more suitable for your project. 

Hand removal means you won’t be working with any chemicals but you will need to make up for it with labour! It can be a lot of work to remove paint in large areas by hand. It’s not an option if you have old paint to remove as it may contain lead. Scraping will release lead particles into the air and can pose a health risk, so if you have old paint it’s best to choose a different method. 

Using a chemical method can be a bit messy but is extremely effective. Some chemical paint removers can be very harsh, so use with caution. However, this is a good choice when you aren’t able to do the whole wall by hand. 

Not sure which method is best for your particular project? An expert interior painter can provide custom advice based on your walls.


3. Working by Hand

If you’re working by hand, you’ll want to start by scraping any loose paint with a brush. Your brush should have wire bristles for the best effect. Use your brush slowly over the entire wall in sweeping motions to remove as much as you can. 

After this step, use a sharp scraper to remove the paint. You may need to use this in combination with an oscillating scraping tool to really tackle the big sections. If you still have paint to remove, use sandpaper by hand or with an oscillating power tool to slowly work over the entirety of the wall. 


4. Working With Paint Stripper

It’s best to use a paintbrush with your paint stripper to apply it. Try and find a gel version so it is less likely to drip and make a mess. Also, check that it will work with the type of paint on your wall. Make sure that your area is well-ventilated since you’ll be working with chemicals. 

Starting at the top, brush your paint stripper over the wall before allowing it to sit as directed, long enough that it penetrates the paint. You may find it easiest to work one section at a time. Then, use a paint scraper to remove the paint. Have a bucket handy to collect the old paint so it is easy to dispose of properly. 


5. Clean up

After the paint is removed from your walls, it’s time to clean up. Be careful when removing your drop cloths from your room so that all chips stay contained. These need to be disposed of properly, so check with your local guidelines — especially if you suspect you have lead paint remnants. 

After the drop cloths are gone, be sure to wash the walls to ensure all dust and paint particles have been removed. This will leave your walls in great condition for future paint or wallpaper plans.

How to Remove Flaking Paint From Walls

To remove flaking paint, you’ll need to use a scraper and wire brush in combination for the best results. First, use your scraper to remove large flakes of paint. Then, use your wire brush to ensure all edges are clean and free of flaking paint. This can be especially helpful if you have noticed flaking paint near window frames and hard to reach areas or on corners. 


Flaking Paint on Walls


After you’ve removed all of the flakes, you can decide whether you need to continue removing all of your paint with a manual scraping or chemical method. Or, if you plan on painting next, make sure to check your walls for any damage or cracks that will need to be filled before you start.


How to Remove Emulsion Paint From Walls

Removing dried-on emulsion paint can be a bit difficult, but it’s not impossible. Use a paint stripper designed for acrylic or latex and follow the steps above for chemical removal. 


Emulsion Paint


You may also want to consider a heat gun as this can soften and loosen paint that has built up in certain areas. 

A wet sponge can thoroughly remove all of the softened emulsion paint from your walls. This, in combination with your scraper, is sure to leave your walls clean and paint-free. Washing your walls will also help to remove any leftover chemical residue to help prep before painting.


Summary

These tried and true methods are the best way to get rid of flaking, peeling, or bubbling paint that is causing an unsightly mess. So pick up your paint scraper and set down your drop cloths to get started. Short on time? Hire a painter and decorator to help out with paint removal and applying a stunning new coat of paint!

Why Its Important to Treat Damp Walls First


Painting over walls that are damp can cause some major problems! Improperly prepared walls are actually a very common DIY mistake. Taking the time to deal with damp is essential and can reduce a lot of frustration.

How to Paint Stairs - 5 Simple Steps to a Great New Look For Your Staircase


Stairs are not just an essential way to connect different levels of your home; they are a beautiful part of it!

Read on for our tips on how to make your stairs look brand new with a fresh coat of paint. 

Then to plan the budget for your painting project head over to our Painting & Decorating Price Guide for further information!


Essential Materials For Painting Stairs

Before you begin the project, make sure you have the right materials on hand. This will ensure you can work steadily after you’ve started without interruptions. 

If you hire a painter and decorator they will take care of gathering these essential materials for you once you've picked out the paint colour. Keep in mind though that if your painter and decorator is purchasing the supplies the cost for this will be added to their invoice to cover the material expenses.

  • Sandpaper in a variety of grits from coarse to fine 
  • Paintbrush (use a type recommended for the paint you have purchased)
  • Paint roller 
  • Drop cloths
  • Painters tape
  • Primer
  • Paint suitable for flooring surfaces (look for durability and slip-resistance)  


Painting Stairs


If your stairs are in an area that sees a lot of use, you will also want to have a scrap of cardboard handy to make each level accessible while you’re painting. This can be used as a reminder of which steps can be used during the painting.

 

How to Get Your Stairs Ready

Getting your stairs ready for painting is crucial for getting good results. In fact, proper preparation is a key factor in performance and longevity, so don’t skimp out when it comes to preparation. 

An important step is deciding on the new look for your stairs. This will help you get the right materials to start the job, and assurance that it will be executed properly. Look online for some ideas about how stairs can be refreshed or even transformed! 


In general, you’ll want to choose a darker colour on your stair treads. The parts being walked on regularly tend to accumulate dirt, and a darker colour helps to disguise this. A lighter colour works well on the riser for contrast. 

You can also use a single colour on your stairs, blending them with the shade on the walls or in contrast. Remember that your railing is another part of your stairs that needs to be painted, so include this in your calculations for paint coverage!
