How to fix a hole in the door?

April 2022 – Most average doors in a house or apartment are quite light and even fragile compared to doors with a more massive core. The former have, for the most part, hollow cores that can be damaged very quickly in a moment of carelessness.

They say misfortune never rests. It does not need to take much to unintentionally cause the damage and damage furniture or worse, ourselves. As we mentioned in the introduction, most indoor doors in our apartments or houses are made of light, non-massive materials. Light, non-massive and even hollow doors can be quickly damaged or punctured, for example, when moving furniture from one room to another, when renovating or doing other household chores.

Damage to the door is not pleasant look and we usually can not wait long to repair or even buy a new door. If the damage to the door is not too great and we do not need to buy new ones, we can also repair the door ourselves with the help of appropriate tools and means to fill the hole in the door (such as PUR foam).

The best way to repair a damaged door is by filling a hole in the door. This will prevent the door from cracking. The filler will prevent this because it hardens immediately after application. The repair process is quite simple and does not require excessive prior knowledge or skills. This type of repair procedure is similar to repairing holes in a (dry) wall or in other materials.

To repair a hole in the door you need:

– Neostik PUR foam UNIVERZAL
– Safety gloves
– Multi-purpose knife
– Sanding paper or orbital sander
– Cleaning cloth
– Putty knife
– Neostik epoxy putty EPOXY KIT
– Coating for wooden surfaces
– Brush

Door repairs can be undertaken without removing the doors from the hinges. However, the repair will be much easier and more accurate if you remove the door anyway and sand it before repairing it and clean the surface with a cloth. Once the surface is cleaned and ready, you can start repairing or filling the hole in the door.

To fill the hole in the door, you will need Neostik PUR foam Univerzal, which allows many applications in construction and electrical installations, in the filling of pipes and other materials. Special formulation provides good adhesion to many coatings. Neostik Pur foam Universal is made from high quality raw materials and additives that provide optimal sound and heat insulation. If you are dealing with PUR foam for the first time, let us remind you that it tends to cling to materials such as textiles, wood and the like. PUR foam is quite difficult to remove, so be as precise and careful as possible when applying it.

We recommend the use of protective gloves when applying PUR foam. Apply PUR foam to the damaged surface or spray it into the hole. PUR foam expands after application and fills the gap inside the door. Once the PUR foam hardens, simply cut it along the surface of the door where some unwanted residue may have remained. Then apply a filler to the filled surface to smooth the surface of the door. This will make the door surface resistant to additional damage and possible cracks that could occur if the door is not repaired.

For this work we recommend the use of epoxy kneading compound Neostik epoxy putty EPOXY KIT, which is used for gluing, repairing and sealing cracks and pipes, quick repairs of pipelines, radiators, tanks, underwater repairs (aquariums, swimming pools), anchoring screws and the like. The epoxy can be sanded after it dries. The surface thus becomes flat and smooth and blends in with the rest of the door surface.

Remove excess epoxy with a suitable knife. You must be careful and try to smooth the surface along the edges. If necessary, you can sand the surface lightly at the end, so that it is not uneven.

To make the repair really flawless, you can also apply a wood coating finish to the repaired door, which will nicely fill in the last small visible imperfections and make the damage completely invisible.
