How to Remove Wood Cracks : A Guide to Filling Longitudinal Cracks That Form in Wood . Remedies for Cracks and Cracks in Wood.
After seeing “ how to glue wood ”, we continue to talk about the typical problems that we can encounter at home: the cracks and fissures that form in the wood.
Why do cracks form in wood?
More than narrow cracks, sometimes they look like real cracks. In reality, these are cracks that form on wooden panels or on solid wood beams (solid wood, noble wood) or laminated wood, due to temperature changes or excessive heating. These wood cracks are generally longitudinal or in any case follow the grain of the wood. They can be more or less deep, more or less wide or long… In any case, the repair procedure consists of filling the cracks with a filler or, even better, with resins.
Large cracks in the wood
When dealing with very large cracks or large cracks in wood , the best solution is to take a thin strip and push it into the crack until it is filled, then level and paint the surface. When the crack is very large and deep, in fact, filler and resins may not be enough. In the case of large cracks, take a strip of wood that you have soaked in vinyl glue, push it into the crack and then shape it until the thickness is perfectly level. The strip inserted must be of the same essence as the wood you intend to repair.
How to remove wood cracks
When dealing with cracks of a few millimetres, wood filler or liquid sealing resins will suffice .
Wood filler is effective and acts as a sealant, filling and gluing. There are different types of wood filler on the market, choose one that can be treated just like wood.
It is easy to find wood filler or liquid resins on the market. You can go to any DIY store or take advantage of online shopping. At “ this Amazon page ”, for example, you can find an excellent wood filler offered at the price of 12.08 euros with free shipping. How is it used? It depends on how wide the crack is: in the case of very wide cracks, after application it is necessary to put the surface under pressure, perhaps in a vice, so that the filler acts as a glue and not just as a filler. If the surface is not put under pressure, the filler will only have a filling action.
How to fill cracks in wood
If you are very handy, do it with a stick, otherwise, wear gloves and handle the putty with your hands (yes, with your hands!).
Spread a little paste (wood filler) near the crack and use your fingers to press until it is filled. In larger cracks, however, it is better to use the spatula so as to apply the right pressure first following one angle of inclination and then the opposite one (to be sure to completely fill the crack in the wood ).
Before the filler solidifies, remove the excess with a slightly damp sponge. Wait for the wood filler to solidify completely. Sand with sandpaper to perfectly level the surface. If you spread the filler with your fingers, a very fine grain sandpaper (400) will be enough, but if you messed up with the stick, you must sand first with a coarse grain sandpaper (200) and then use the thinner one.
Do not use sandpaper that is too coarse because the filler, even when hardened, is easy to remove since it is not painted. To restore a homogeneous surface, you can paint with a mordant (natural or colored) or apply a coat of natural wood wax.
