1. Timbermate Wood Filler

Timbermate Wood Filler is unlike any other grain filler or wood putty on the market, and it dries quickly and accepts stains wonderfully. You can store it for a long time and use it for future woodwork repairs.

Its user-friendliness makes it suitable for even the most inexperienced DIYers, and cleaning it only requires soapy water. It sticks well to wood and doesn’t dry out or fracture.

Nothing will happen until you put a finish over it. In case you don’t like the way it looks, or the shade, or its overall appearance on the surface, you can easily dilute it to wash it away.

4. Elmer's E855 Carpenter's Wood Filler, 3.25-Ounce Tube

You can use Elmer’s E-855 Carpenter’s Wood Filler to do the job of patching the floor gaps or cracks at home.

This carpenter’s wood filler, like Elmer’s, can be sanded to a clean finish after being used to fix imperfections. We like that it doesn’t shrink or crack and may be sanded and painted.

(For more options, check out these stainable wood fillers here!)

It’s also nice that a simple mixture of water and soap can eliminate any lingering residue. The paste can be made smooth without sanding by adding a little water. Wood filler segments have different absorption rates from paint; thus, a priming coat is necessary if you paint the finished product.

(For a reliable primer option, know the best choice between Zinsser vs Kilz primer.)

Buyer’s Guide for Wood Floor Fillers for Repairing Cracks

Type of Filler

Wood fiber, cellulose, and gypsum are all examples of water-based fillers. They are sensitive to water and emit very little smell, making them perfect for indoor use. They dry rapidly and are simple to clean with soap and water.

Solvent-based fillers, on the other hand, are epoxy [1] and vinyl composite. They have stronger scents but adhere more securely and can withstand the elements, making them great for outdoor jobs.

(For high-quality options, consider these exterior wood fillers for outdoors!)

It may take some time for them to harden fully, and they might be difficult to clean up after.

Durability and Strength

Wood fillers are generally durable and strong. They can be painted, sanded, and stained when it has dried quickly and becomes very hard.

Although some wood fillers’ application is limited to interior surfaces since wood fillers dry rock hard and may crack due to environmental conditions that cause expansion and contraction, cracking is far less common indoors because of the stable temperature and humidity.

Drying Time

Wood fillers require a certain amount of time to dry before you can use them. Wood fillers with latex dry quickly, allowing you to finish the job sooner.

You won’t get the same results using oil-based fillers because they dry and set more slowly. Choose a filler that dries within the time frame recommended by the manufacturer.
