Step by step guide on fixing a damaged door

If the door needs replacement, it is best to hire someone who is an expert in Modern Kitchens. If the damage is not very severe, you can use this guide to DIY.

  1. Choose the filler material: You can choose between putty and a filler to fill the cracks or crevices. Both materials are slightly different. Putty doesn’t harden up and is flexible. This is a good option if you don’t want to sand or paint the door. The filler hardens when it dries up and can be sanded. So if you intend to paint the door use a filler instead of putty.
  2. Apply the filler: A filler is a durable and long-lasting solution to cracks in the door. For best results, you must use a good quality filler. Cover the entire crack from end to end and make sure you cover all the cracks.
  3. Allow the filler to dry: Scrape off any excess filler, you don’t need to worry about any uneven surface and you will have to sand it later. Good quality filler has a shorter drying time. However, you must allow the filler to dry properly.
  4. Sand the surface to make it smooth: Sanding will give you a smooth finish where you applied the filler material. Sand the target area using sandpaper with gentle strokes. Medium grit sandpaper should suffice for this task. Gentle strokes will ensure that you don’t damage the door further.
  5. Paint: Once you have a smooth surface, it is ready to be painted. Use a paint that is similar to the old paint, so that it gels well with the original paint. You can use a roller or a paint brush to paint the door. Allow the paint to dry.

If there are medium sized cracks on the door, you can use epoxy glue to fill them as putty or filler will not work here. For large cracks use a wooden spline, inserting it into the crack is the best solution.

By following these steps you will be able to repair any damaged door on your own and restore it to make sure it lasts long.
