5 Top Techniques of how to fill screw holes in wood before Painting
To get a fine outlook of your wooden project, you may not leave these holes without proper filling. Let’s check out the details of 5 best method one by one:
1st: Using Wood filler patch
With the help of a product named wood filler or wood plastic, you can remove nail or screw holes easily. Let’s see step by step guide of this procedure.
Step 1: Cleaning the surface for patching
The first step is to clean the area around the screw holes. You can use a wet but soaked cloth or SandPaper for this purpose. Keep these important points in mind.
- The area should be dry completely if you are using a wet piece of cloth for cleaning
- holes should always be few centimeters deep below the wood surface.
Step 2: Preparing the wood filler
Take 1 scoop of high-quality Filler and a pinch off hardener and mix them with a putty knife. Remember two-part fillers are easy to mix and longer in effect.
- Don’t increase the amount of filler for a couple of screw holes. Always keep the filler quantity equivalent to the Golf ball size.
Step 3: Mixing the hardener
Now it’s mixing time. Use a putty knife to apply the mixture to the hole. The knife blade should not be longer than 1.5 inches in width to get more control. Drop the required amount of filler over the opening and spread it. Point to Remember:
- it is always easy to handle the little amount as it spreads a lot. So, don’t exceed the quantity.
Step 4: Levelling the surface to set the filler
After spreading, let the patches set according to instructions given on the box. It may take 15 to 20 minutes to set properly. To get a more smooth surface use Sandpaper over the scrolling area. Remove remaining wooden pieces or carefully.
This technique also works well on metal projects. But the type of filler is different for metallic bodies.
2nd: Using Wood glue
Using Wood glue is one of the cheapest, simplest and easiest methods of removing holes in wood.
Let’s see step by step guide of this procedure –
Step 1: Drop glue in the screwing area
After driving the screw, drop wood glue in that area. You may use Gorilla glue, PVC glue of anyone you like.
Step 2: Wait to set the glue
The adhesive of any type needs time to cure and set properly. So, after applying it wait for at least 45 minutes to get it dry.
Step 3: Sand the glue line
Sand the glue line with fine sandpaper. Wipe away extra glue carefully.
3rd: Using a plug or piece of wood cutting
Plugs are pieces of small wood cutting just like the size of the nailhead or screw hole. These pieces always come as a part of the wood you are using in your projects. This process is widely used for the largest projects with vertical cracks like holes.
Let’s see step by step guide of this method –
Step 1: purchase the plug
You may get these plugs from any Hardware Store. These plugs are available in the same color as your wooden project. Two commonly used plugs are oak wood plugs and screw caps.
Step 2: Make your own plugs
For custom projects, carpenters often make their own plugs using drills. Here is an informative video to guide you on how to cutter plugs.
Step 3: Drill to make the shallow house to drive the plug.
Now drill the screwing area a bit to the size of the plug you made. It should not be more than ¼ inch.
This depth depends mainly on your needs or the requirement of the woodwork. Put a screw in this drill.
Step 4: Fit plug right above the screw
After nailing the pilot hole, insert the plug right above the head of the score. Don’t forget to apply filler or wood glue under the plug.
Step 5: Sand the surface
Now sand the surface to get the final touch with sandpaper. Now it’s ready for stain. It’s completely invisible.
4th: Using Chisel and clamps for recoiling wood
By using a chisel, you can make a pilot hole in the wooden surface. It will curl away from the wood. Now put clamps in the pilot hole and then fit it with wood glue. The coiling area settles around clamp in a way that it gets to level to the wood surface. Finally, sand it to get the final touch. Clamps of high quality and each size are easily available.
5th: Using Wooden Scrap and glue
Don’t worry if you can’t buy fillers, plugs, and hardeners then go for shave off scrap material of wood itself. Fill the screwing area and put glue on it. Wait for the glue to set. Sand it with sandpaper. It will make all kinds of roughness invisible.
