Hollow core doors are much cheaper and more common than solid wood doors but are also more fragile and prone to damage. While holes or ugly scratches on doors may seem difficult to fix, they can actually be fixed in just a day or two. Just patch up holes or fill in scratches before refinishing and your door will look like new in no time!
Steps
Patch holes or cracks
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b2/Repair-a-Damaged-Hplow-Core-Door-Step-1-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-1-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b2/Repair-a- Damaged-Hplow-Core-Door-Step-1-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-1-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Cut away any loose or broken pieces of wood around the hole or crack. Depending on the extent of the damage to the door, there may be crumbs or debris around the edge of the hole or crack. Before repairing, use a multi-purpose knife to cut the damaged wood so that only a neat hole is left, without jagged edges. [1] X Research Source
- Always cut away from the body when using a multi-tool, especially when cutting hard materials such as wood.
- You may need to widen the hole or crack before you start repairing. It is easier to patch a large hole with no damaged wood than to patch a smaller hole that has broken or broken pieces.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/9c/Repair-a-Damaged-Hplow-Core-Door-Step-2.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/9c/Repair-a-Damaged-Hplow-Core-Door- Step-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Fill the hole with tissue paper. While it doesn’t strengthen the door or fix it, paper towels are an easy to find and inexpensive material to hold the foam in place as it dries. Wrap a few sheets of tissue paper and tuck it around under and around the edge of the hole or crack you want to fix. [2] X Research Source
- Napkins work well because they’re lightweight so you can tuck them inside a hollow core door. If you don’t have a tissue, you can use a tissue or something similarly light.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/be/Repair-a-Damaged-Hplow-Core-Door-Step-3.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/be/Repair-a-Damaged-Hplow-Core-Door- Step-3.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use insulating foam to fill the hole. Insulation foam sealant comes in the form of a spray bottle with a long spray nozzle on the top of the bottle. Aim the nozzle at the hole or crack in the door and spray. The foam will expand, filling the space inside the door and may spill some out of the hole onto the surface of the door. [3] X Research Sources
- Insulating foam is available online or in building materials stores. With a small perforation, you can choose the one with less bloom for ease of use.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/ee/Repair-a-Damaged-Hplow-Core-Door-Step-4-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-4-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/ee/Repair-a- Damaged-Hplow-Core-Door-Step-4-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-4-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Wait overnight for the insulation foam to dry. Once you’ve filled the hole or crack with insulation foam, you need to wait for it to dry completely before cutting or sanding. Wait about 4-5 hours or preferably overnight for the material to dry completely. [4] X Research Sources
- See the instructions on the insulating foam product you are using to see how long it will take to dry.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/dd/Repair-a-Damaged-Hplow-Core-Door-Step-5-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-5-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/dd/Repair-a- Damaged-Hplow-Core-Door-Step-5-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-5-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use a multi-purpose knife to scrape off excess foam. Hold the knife over the foam protrusion so that the blade is level with the surface of the door. Slide the blade down the door surface to trim the excess until the foam is no more than 2.5 mm below the door surface. [5] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/65/Repair-a-Damaged-Hplow-Core-Door-Step-6-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-6-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/65/Repair-a- Damaged-Hplow-Core-Door-Step-6-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-6-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Apply a layer of automotive putty to reinforce the hole. Mix 1 part automotive putty with 1 part curing agent and spread the mixture over the opening in the door. Use the edge of a putty knife to spread and press the mixture into the hole in the door, filling in any gaps so that it is almost level with the surface of the door. [6] X Research Sources
- Automotive putty is a very good door firming compound but can be difficult to use. It is often packaged with a curing catalyst that acts as an activator. This product is available online, or at a hardware store or auto repair shop.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8e/Repair-a-Damaged-Hplow-Core-Door-Step-7-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-7-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8e/Repair-a- Damaged-Hplow-Core-Door-Step-7-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-7-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Seal the hole with grout if you want a quick fix. If you don’t have car mattite, you can use grout to seal the hole. Use a putty knife to scoop some grout onto the hole in the door. Apply mortar with long, smooth movements so that the surface is as smooth and even as possible. [7] X Research Sources
- Mortar is a cheap material, easy to buy and very easy to use.
- Mortar is available online or at building materials stores.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/cd/Repair-a-Damaged-Hplow-Core-Door-Step-8-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/cd/Repair-a- Damaged-Hplow-Core-Door-Step-8-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-8-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Wait an hour to dry. Regardless of whether you’re using mortar or automotive putty, you’ll need to wait for the material to dry completely. Wait for the mixture to dry until it is hard to the touch. [8] X Research Sources
- Read the directions for use on the automotive grout or putty packaging for more information on how long the mixture will take to dry completely.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/61/Repair-a-Damaged-Hplow-Core-Door-Step-9-Version-2.jpg/v4-460px- Repair-a-Damaged-Hplow-Core-Door-Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/61/Repair-a- Damaged-Hplow-Core-Door-Step-9-Version-2.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-9-Version-2.jpg”,”smallWidth”:460 ,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Smooth the door surface. Use 100-120-grit coarse sandpaper to smooth the patch. Rub grout or automotive powder until the patch is flat and level with the surface of the door. [9] X Research Source
- The sanding step will make the patch smoother and less visible. However, the edge around the hole or crack will be rough after scrubbing. To fix this and make the door look like it is not patched, you can use wood paint or wood cleaner to paint the surface of the door.
Repair scratched door
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f4/Repair-a-Damaged-Hplow-Core-Door-Step-10.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-10.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f4/Repair-a-Damaged-Hplow-Core-Door- Step-10.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Use fine sandpaper to remove paint and debris. Use 320-grit sandpaper to smooth away areas of peeling paint and/or wood chips. Clean the scratched area so you can patch it up instead of re-gluing the scraps. [10] X Research Source
- If the wooden door has a lot of debris, use thick gloves when sanding to avoid injury.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/27/Repair-a-Damaged-Hplow-Core-Door-Step-11.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-11.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/27/Repair-a-Damaged-Hplow-Core-Door- Step-11.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Apply wood glue to the scratched area. Squeeze or spread some wood sealant over the scratch on the door. Use your finger or a spatula to spread and press the glue into the scratches. Try to apply a smooth, even and even surface to the door surface. [11] X Research Source
- Wood filling scissors are available online or in hardware stores. The product comes either pre-mixed in a tube or has two ingredients that must be mixed together before use. Read the instructions on the product packaging for best results.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/6b/Repair-a-Damaged-Hplow-Core-Door-Step-12.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-12.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/6b/Repair-a-Damaged-Hplow-Core-Door- Step-12.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Wait for the glue to dry for about 15-20 minutes. Wood sealants need to be stable and adhere firmly to the wood. After applying glue to all scratches, you should wait 15-20 minutes until the glue is hard to the touch to dry completely. [12] X Research Source
- Read the wood sealant’s instruction manual for more information on drying time.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f7/Repair-a-Damaged-Hplow-Core-Door-Step-13.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-13.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f7/Repair-a-Damaged-Hplow-Core-Door- Step-13.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-13.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Sand the wood sealant with 320-grit sandpaper. Once the wood sealant is dry, use fine sandpaper to smooth out the area that was previously scratched. Scrub with a smooth and slow motion to remove excess glue and smooth the surface of the door. [13] X Research Source
- The rough spots will become more prominent when you paint over the smoothed area. Use your hand to feel all over the glued surface to detect areas that need to be smooth and flat.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/61/Repair-a-Damaged-Hplow-Core-Door-Step-14.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-14.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/61/Repair-a-Damaged-Hplow-Core-Door- Step-14.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-14.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Clean the surface with a damp paper towel or damp sponge. The process of scrubbing wood and painting the scratched area can create a large amount of dust and debris that will deteriorate the finish of the door. Dab water on a clean cloth to moisten and gently wipe the entire surface of the door to remove dust.
Refinishing the surface of the hollow core door
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/15/Repair-a-Damaged-Hplow-Core-Door-Step-15.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-15.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/15/Repair-a-Damaged-Hplow-Core-Door- Step-15.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-15.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Smooth the patch and wipe off the dust. To make sure the paint or wood cleaner adheres evenly to the area you’re going to paint, you’ll use 220-grit sandpaper to smooth the area. Use a vacuum cleaner or damp rag to remove dust and debris. [14] X Research Source
- Dust will make it difficult for the paint to adhere to the wood and create an uneven surface. You need to clean the dust before finishing the door.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/bb/Repair-a-Damaged-Hplow-Core-Door-Step-16.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-16.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/bb/Repair-a-Damaged-Hplow-Core-Door- Step-16.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-16.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Remove metal fittings or door hinges. It’s best to paint the entire door for an even finish, rather than just painting the area. Use a screwdriver to remove metal parts on the door such as the doorknob, hinges, or latch socket near the bottom edge of the door. [15] X Research Source
- If you want to completely remove the door from the hinge, press your fingernail into the bottom of each hinge pin and knock the latch out with a hammer. This way, you will be able to finish the door elsewhere and the job will be easier.
- Check the screws in each screw position to select the correct type of screwdriver to use. It is always recommended to use a screwdriver to remove and attach the screws of the hollow core door, because electric drills are easy to damage the door.
- Another way is to use masking tape to cover up areas you don’t want to be painted over.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/7d/Repair-a-Damaged-Hplow-Core-Door-Step-17.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-17.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/7d/Repair-a-Damaged-Hplow-Core-Door- Step-17.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-17.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Look for paint or varnish that matches the color of the door. Choosing the right paint color will help the door color match with the rest of the doors in the house. You can ask the staff at the building materials store to show you samples of the paint or ask them to choose a paint color that matches the color of the door. [16] X Research Source
- While the idea of photographing the door to find the right color sounds good, it doesn’t always work. Indoor lighting, the type of camera used to shoot, and printed photos may change color.
- If possible, bring in a sample of the door to compare – like a piece of the door you cut out when you started fixing it.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/ff/Repair-a-Damaged-Hplow-Core-Door-Step-18.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-18.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/ff/Repair-a-Damaged-Hplow-Core-Door- Step-18.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-18.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Apply an even coat of paint over the entire door. Use a large multi-purpose paint brush or paint roller to apply a coat of paint to the door. Paint all the grooves or doorways first, then paint long, even strokes over the rest of the door to avoid leaving visible lines. [17] X Research Source
- If you’re afraid of staining your work area, you can spread a tarp or some old newspapers under the door before you start painting.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/50/Repair-a-Damaged-Hplow-Core-Door-Step-19.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-19.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/50/Repair-a-Damaged-Hplow-Core-Door- Step-19.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-19.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Wait for the door to dry for 3-4 hours. Once you have applied the first coat, wait for 3-4 hours to dry. Even a light touch can damage the paint on the door, so you need to make sure everyone in the house knows the paint is still wet. [18] X Research Sources
- Read the instructions for use on the paint or wood cleaner packaging for more information on how long it takes for the paint to dry.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c6/Repair-a-Damaged-Hplow-Core-Door-Step-20.jpg/v4-460px-Repair-a- Damaged-Hplow-Core-Door-Step-20.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c6/Repair-a-Damaged-Hplow-Core-Door- Step-20.jpg/v4-728px-Repair-a-Damaged-Hplow-Core-Door-Step-20.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight” :546,”licensing”:”<div class=”mw-parser-output”></div>”}
Apply a second coat and wait for it to dry. Each layer of paint added will help the door color to be a little darker and overall better. Once the first coat has dried, you will apply a second coat to cover any visible imperfections after applying the previous coat. Wait for the door to dry completely until it is no longer damp or sticky to the touch. [19] X Research Source
- Many interior paints take days to dry completely. Be careful with the door for 1 week after painting to avoid damaging the paint.
- You can apply as many coats of paint or paint as you like, but 2-3 coats is enough.
Advice
- If the hole in the door is quite large, you may need to replace the whole door.
