Painting a room can be a daunting task, but with the right preparation, the process can be made much smoother. Before you begin, make sure you have all the necessary tools, including painter's tape, drop cloths, sandpaper, primer, paint, and brushes or rollers. Next, remove all furniture from the room or cover it with a sheet or drop cloth. Then, carefully inspect the walls for any holes or cracks, filling them in to ensure an even surface. It is also important to clean the walls to remove any dirt, dust, or grease, which can be done with soap and water, or a degreaser like trisodium phosphate if the walls are particularly dirty. Once the walls are clean and dry, sand them down and apply primer before painting.

What You'll Learn
Clean the walls
Dirt, dust, and even cobwebs can accumulate on walls. Cleaning the walls before painting is essential for an attractive final paint job. Start by carefully inspecting your walls for any holes or cracks. If you find any, fill them with patching paste or a similar product, using a filling knife to ensure the filler is evenly applied. Before filling, clean the gaps with soapy water and rinse.
Next, use a duster to remove dust and cobwebs. Start in the upper corners of the wall near the ceiling and work your way down. Pay extra attention to the baseboards, running the duster or a rag along the entire length of the room. If the walls are particularly dirty, greasy, or covered in oil (this may be the case in kitchens), you may need to use a degreaser like trisodium phosphate (TSP). Mix the TSP powder with warm water and use it to wipe down the walls.
After sanding down any spots on the wall, be sure to wipe off any excess dust. You can use a damp sponge to give the walls a final wipe-down to ensure they are free of dust and soap residue. Allow the walls to dry thoroughly before painting.

Repair wall imperfections
To prep a room for painting, it's important to repair any wall imperfections for a smooth and professional finish. Start by inspecting the walls for any holes, dents, cracks, or blemishes. Small nail holes from picture hooks can be easily filled with spackling or joint compound. Use a putty knife to apply a thin layer of spackle over the hole, and then smooth the surface with a damp sponge or sandpaper once dry. For larger holes or dents, use a self-adhesive patch or a piece of mesh tape to cover the area before applying joint compound. This will provide a stronger and more durable repair. Allow the compound to dry completely, and then lightly sand the area until it is smooth and even with the wall.
For cracks in the wall, use a V-shaped tool to scrape out and widen the crack, removing any loose debris. Then, fill the crack with a flexible, paintable caulk, which will help prevent the crack from reappearing. You can also use

Prime the walls
Priming your walls is an essential step in the painting process. It helps to ensure that your paint job looks smooth and professional. Here are the steps you should take to prime your walls effectively:
Start by inspecting your walls carefully. Look for any holes, cracks, or imperfections that need to be filled. Use a bright light, such as a 1000W halogen lamp, to shine on the wall sideways. This will help you identify any imperfections that need to be addressed. Circle or mark the areas that need to be filled or sanded.
If you're working with fresh plaster, it's important to use a primer or a "mist coat" before applying paint. Fresh plaster is porous, and without a primer, the first coat of paint may be absorbed unevenly, requiring more paint and effort to achieve a consistent finish.
To fill in any holes or cracks, use a filler or spackle and a filling knife to carefully push the filler into the gaps. Make sure the surface is as flat and even as possible. If you're filling in gaps near baseboards, clean the area with soapy water and rinse it before filling. Once the filler is dry, sand it down to ensure a smooth and even surface.
After sanding, wipe down the walls with a damp sponge or a warm, wet cloth to remove any excess dust. This step is crucial, as dust can get stuck in your paint and ruin your final paint job.
Once the walls are clean and dry, it's time to apply the primer. Choose a primer that is suitable for your surface, such as a PrepRite ProBlock Primer/Sealer for sealing stains or a self-priming paint. You can also use a "mist coat" by diluting your paint with water (700ml of paint to 300ml of water). Apply the primer or mist coat evenly to the walls and let it dry completely before proceeding to paint.
By following these steps, you'll ensure that your walls are properly primed and ready for painting. Priming the walls may take some extra time, but it will help you achieve a high-quality and long-lasting paint finish.

Protect furniture and floors
Protecting your furniture and floors is crucial when prepping a room for painting. Start by removing as much furniture as possible from the room. If there are heavy pieces that cannot be removed, move them to the centre of the room and cover them with protective sheets or drop cloths. This will shield them from paint splatters and spills.
Next, turn your attention to the floors. Spread out drop cloths or plastic sheeting to cover the entire floor area. Ensure the sheets overlap to provide comprehensive protection. If there are any gaps between the wall and the floor, stuff small pieces of cloth or paper into them to prevent paint from getting through.
Before you begin painting, it is essential to prepare the walls. Clean the walls thoroughly to remove any dirt, dust, or grease. Use a duster or a damp cloth to wipe down the walls, starting from the top corners near the ceiling and working your way down. If the walls are particularly dirty or greasy, you can use a degreaser like trisodium phosphate (TSP) mixed with warm water. After cleaning, inspect the walls for any holes, cracks, or imperfections. Fill these with a spackling compound or patching paste, using a filling knife to ensure a smooth and even surface. Once the filler is dry, lightly sand the area with fine-grit sandpaper to create a seamless finish.
Finally, use painter's tape to protect areas you don't want to paint, such as windows, door frames, and light switches. Press the tape firmly against the surface with a putty knife to create a seal and prevent paint from seeping underneath. Remember to remove the tape promptly after painting, as leaving it on for too long can cause the paint to peel when removed.

Seal stains
When prepping a room for painting, it is important to seal stains to prevent them from bleeding into your paintwork. Here are some detailed steps and tips to help you effectively seal stains before painting:
Identify the Type of Stain
Different types of stains require different approaches. For example, if you are dealing with rust or metal stains, you should use a specialised oil-based, fast-drying metal primer, such as Rust Scat. For mould, you must first kill it with a mould killer and then apply a mould-killing primer.
Choose the Right Primer
Using a primer is essential for sealing stains. Look for a stain-blocking primer, such as Kilz, which is suitable for most cases. However, some strong stains may bleed through, so it is important to do an extra coat of primer if necessary. If you are working with plywood or SPF woods (spruce, pine, fir), be aware that the resins from tree knots can bleed through a simple primer. In these cases, opt for a primer with strong sealant and stain-blocking qualities, such as BIN or an alcohol-based version.
Prepare the Surface
Before applying the primer, ensure the surface is properly prepared. Sand the area to create a smooth base for the primer to adhere to. Use a bright light, such as a 1000W halogen lamp, to highlight any imperfections. Circle or mark these areas to ensure you don't miss any spots. After sanding, wipe down the surface to remove any excess dust.
Apply Primer
Follow the instructions on your chosen primer for application guidance. Typically, primers are applied with a brush or roller. Ensure you have good ventilation during application, and consider using dollar-store brushes if you are concerned about brush preservation. After priming, seal the brush inside the can to prevent mess.
Allow Drying Time
Give the primer sufficient time to dry before proceeding. Primer typically dries quickly, especially in warm conditions. However, it is important to allow enough time to ensure the primer is fully effective in blocking stains.
By following these steps, you can effectively seal stains and create a smooth base for your paintwork, ensuring a professional and long-lasting finish.

Frequently asked questions
You'll need painter's tape, a drop cloth, sandpaper, primer, paint, and a brush or roller. You should also wear protective equipment, such as gloves and a respirator, to avoid inhaling dust or fumes.
First, carefully inspect the walls for any holes, cracks, or stains. Fill in any holes or cracks with a filler or patching paste and sand the walls to create a smooth surface. If there are any stains, seal them with a primer/sealer. Finally, clean the walls with soap and water, and wipe them down with a damp sponge to remove any soap residue.
Priming the walls is not always necessary, especially if you're painting over paint that's in good condition and not too glossy. However, if you're painting over a porous surface, such as fresh plaster, or if there are stains or imperfections, it's recommended to use a primer to ensure better adhesion and a more consistent finish.
Remove as much furniture from the room as possible. If some pieces of furniture are too heavy to move, cover them with protective sheets or drop cloths. To protect the floor, spread out drop cloths to cover any exposed flooring areas.
