Method-3: Waterproofing with Resin and Acetone

One of the easiest and most durable ways to waterproof bathroom wooden floors is to use a mixture of resin and acetone. As a result of wood waterproofing in this process, your wood retains its waterproof properties for up to 5 years.

Take a paint brush and soak the brush in the mixture. This time apply it to the wood surface. Make sure the whole wood is evenly coated.

 

Step-4: Dry the first coat:

Usually, a mixture of resin and acetone dries quickly. It may take 30-60 minutes to dry well.

 

Step-5: Re-apply the resin coat:

Once the first coat has dried well you apply the second coat in the same way.  Remember, resin should be applied very gently. To get good results in this work you need to do 5-6 more coat.

Make a mixture of resin before each coat. If you want to get a glossy coating, add liquid wax to the mixture and apply it to the final coat.
