Another great solution for preventing any kind of splitting issues on wood is salt paste. Using salt paste on your wood pieces helps them dry up quickly. When the wood has dried up, it doesn’t let any moisture or air pass through easily.

It’s safer than using any sealant because it’s free of chemicals. Using household items, you can make a salt paste and apply it to your wooden pieces. So, this is a very easy-to-follow method as well.

To prepare the salt paste, you will need salt, cornstarch, egg, and water. First, make a salt solution with water and keep it like that for four hours. Then, you have to add cornstarch. Afterwards, add the eggs to the solution and mix them properly. There you have it.

Once you have the salt paste, take a paintbrush and apply it to the wooden piece you want to protect. When the salt paste dries out, you have to remove it but keep in mind that it’s going to be a bit tough.

We have all heard of varnishing wood, right? It’s a great way to give your wooden furniture a new look after the wooden colour has faded. Aside from making it look better, varnish can also help prevent splitting problems in wood.

If you are using this method, don’t forget to get a sealer. Because every time you varnish, you must use a sealer to solidify the varnish. Otherwise, you may face issues of the varnish not being effective or coming off earlier than you expect it to come off.

The process you have to follow isn’t that difficult either. You have to prepare the varnish using some kind of aluminium paint. You have to prepare the sealer. To do that, you can mix warm water and glue. Stir them together for a while, and you will have your sealer.

Before applying the varnish to your wood piece, sand it and clean it. Missing out on this step may cause issues with your varnishing later on, as the wood won’t have a smooth surface. Remember, you might need to apply multiple coatings of varnish.

If varnishing doesn’t seem like a viable option for you, then you can try out paintable wax. Wax works out great for sealing off your wood, so it doesn’t have cracking or splitting problems. The best part is that you can prepare the paintable yourself.

Here’s how you prepare the wax. Start with taking some candles. Then put the candles in a bag and smash them with a hammer. Next, you must measure the weight of the smashed candles inside the bag. Then, remove the wax candle pieces from the bag and start melting them.

While that goes on, you can take a canning jar and put some paint thinner into it. The amount of paint thinner will be the 1/4th weight of the candle that you weighed earlier. Once you put the thinner inside, you can pour the melted candle or wax inside the jar.

At this point, you just have to start mixing the paint thinner and wax. You have to blend the two elements properly, don’t leave any heavy chunks. After preparing the wax, all you have to do is apply it.
