6 Tips to a Perfectly Levelled Drywall
When making drywall repairs, one of the issues that separates DIY projects from professionally done fixes is the uneven surface or unwanted texture that results after the repairs. Uneven surfaces result due to poor workmanship and not the lack of building materials Toronto. Professional drywall finishers use a technique called skim coating in order to come out with a flawless wall. This technique can be used on both newly installed drywall or one that has already been painted to achieve a smooth and even surface. Below are a few tips to get a smooth finish on any drywall surface.
Ensure the wall is thoroughly cleaned
Start by cleaning the wall thoroughly if it has been painted. You can mix a half a cup of trisodium phosphate with 2 gallons of warm water. You can use any other equivalent detergent that is readily available.
Patch all cracks
Go ahead and use joint compound to patch the cracks that may appear when you apply a new coat of paint on the wall. Have the right tools and construction supplies Toronto for this task. You can use a 4 inch knife to evenly spread joint compound on the cracks. After this, go ahead and lay on the drywall tape. Use the same blade to scrape that flat. Give the repairs sometime to dry completely before you proceed.
Apply drywall primer
Drywall primer should always be applied before any paint job. This is what aids the adhesion of the joint compound. It may also prevent humps or bubbles from forming on the wall giving it an unpleasant finish. Choose a reliable primer that is known to offer the best finish.
Choose the right joint compound
The joint compound that you will apply will depend on the kind of wall you are trying to level. If you are leveling a wall that has already been textured or painted then it is best to use the all-purpose joint compound alone without mixing it with any water. However, if the drywall you are leveling is not painted, you can add water to the pre-mixed all-purpose joint compound.
How to apply joint compound
Start by applying a thin coat of the joint compound from one corner of the wall working your way across the surface to the other corner. You can use an 8-inch knife to apply the joint compound. If there is any excess joint compound, scrape it off gently with the blade. You can then apply a second coat of joint compound and then scrape the excess off. Make sure you’ve covered the entire surface.
In most cases, two coats of joint compound will be sufficient especially if you are leveling an unpainted wall. If the wall you are leveling is a painted or textured one, then you may have to apply up to 4 coats in order to give it a nice finish. Always ensure that each coat has dried before you apply a fresh one over it.
Sanding the final coat
Once the final coat is dry, you can use 120-grit sandpaper to level the area. Make sure all the areas are perfectly smooth when sanding. You need to consider any building supply Toronto such as a gas mask that you may need when conducting this process.
