How to Paint Dry Wall: Tips By Interior Painter Brampton

Would you like to have a new Interior paint on Drywall? To do this, you will need to paint some parts, either to refresh the old paint or to completely change the color. Here's a guide to help you prepare your Drywall painting before you take out the brush and roller.

Preparing  for drywall painting

Before you start, must make sure that you have all the important painting tools.

Here is a list of what you might need, depending on the condition of the drywalls and ceiling in the room to be painted:

• Different sized knives
• Plaster to fill
• Putty to fill small holes
• Grid type sandpaper
• Fairly fine standard sandpaper
• Adhesive fiberglass grid
• A sanding block
• A degreaser for walls
• A "Swiffer"
• Basic tools (screwdriver, hammer, exact, etc.)
• A mask and protective glasses
• If possible, a "Shop-vac" type vacuum cleaner

Preparation work may release a lot of dust and dirt (or little if you follow our sanding advice below!). If possible, remove furniture completely from the room. If this option turns out to be too complicated, group your furniture in the middle of the room and cover it with a drop cloth.

Step 1: Prepare for the repair

Before repairing all holes and cracks, remove each nail and screw. You can push the excess drywall inside the wall using the tip of a screwdriver. If necessary, sand the outside of the hole gently until you can no longer feel a bump.

Take the opportunity to correct the imperfections of the old paint that may come out despite the application of the new Interior painting. Small dents are often found on the drywalls caused by excess dried paint. Use the blade of your exact to remove imperfections. In the majority of cases, you will not have to plaster afterwards, but still, check that your corrections are not noticeable when you run your hand flat on the wall. 

Step 2: Repairing holes and cracks

This is where your patching plaster and putty come into play. Make sure you dust well around your holes, otherwise the dust could interfere with your plaster work. 

And if you want to save time, fill in the holes starting with the biggest and ending with the smallest.

If you have to repair a large whole (2 cm 2 and more), it may be preferable to cover it with an adhesive grid (see image below). This will help the plaster to adhere, and the grid will disappear during your sanding.

This way, you are less likely to distinguish between repairs after your Interior painting job is finished. 

For reference, for a whole 2 cm 2, you can easily apply your cast on an area of 20 cm 2 or more.

Besides, try to smooth the surface well, leaving as little excess as possible, but make sure you never dig a cavity towards the inside of the drywall, otherwise you will have to start over. To help you, use a larger knife for larger sized holes.

The principle is the same for cracks, but if they are rather thin, the use of an adhesive mesh is not necessary.

Remember that for larger holes you will need to wait at least 4 hours for the plaster to dry properly, but it is generally advisable to wait overnight before sanding. You can however rely on the indications; drying time varies from product to product. Some filler plasters change colour when completely dry, but they are more expensive.

Step 3: Sanding

This is arguably the most time-consuming step, but by following these few tips you can make sanding a lot less frustrating and dusting a lot less time-consuming.

If you have a lot of sanding to do this, invest in a sanding block that plugs into a “Shop Vac” vacuum. This kind of tool sells for around twenty dollars only. Do not deprive yourself of it. 

By using it, you will reduce the amount of dust that falls to the ground and spreads through the air almost to zero. But don't take a chance, wear a mask and safety glasses anyway, and please don't plug this tool into your new central vacuum. You risk damaging it as plaster dust can pass through conventional filters.

Once the larger one is removed, finish the job with finer sandpaper. 

After you finish, make sure the surfaces you sanded are smooth and level with the wall. 

The best way to do this is to run your hand flat on the surface. You shouldn't feel any bumps or cavities. On the other hand, even if you use the best possible technique, there is a good chance that you will have to plaster some areas. Don't worry, this is completely normal. Do not lose patience and go through the plaster and sanding step again.

Step 4: Cleaning

The following cleaning method is prescribed for latex painted walls. Before giving a basecoat, you should clean your drywalls to remove dirt and dust that might get stuck in the fresh paint. We recommend using a Swiffer to keep you from constantly getting on and off a stepladder, but a large sponge can also do the trick. Provide a boiler of clean water and a boiler of water mixed with a cleaning product such as TSP

Step 5: Basecoat and Paint on Repairs

If you keep the original colour of the your wall you don't need to apply a basecoat. On the other hand, you should ideally cover your repairs with a primer, then a new coat of paint once the primer has dried.  

If all goes well, this will allow you to complete the job with just one final coat, but be sure to stick to the paint drying time!

However, if you change the color, you can still start with a base coat on the repairs and then over the entire surface to be painted. This is the optimal method to prevent the plaster from appearing after the work is completed.
