How to Remove Deck Stains

Refinishing a Deck

Introduction:

I get this question quite often “how to remove deck stains”. Unfortunately the rain and moisture will take its toll on any outside wood regardless of what kind of paint is on it. The idea is that the paint will protect the wood by taking the wear and tear of the moisture and sun but unfortunately the paint has to be refinished from time to time. There is more than one way to refinish a deck but neither way is easy.

How to remove deck stains:

If your deck boards are screwed down you can try to unscrew them and reverse them by flipping them over and re-screw them to the floor joist. The underside of the deck boards will look like brand new since they've never been in the rain or sun. Boards have been cut to go around posts or railing supports will have to be replaced. This is the least expensive and easiest way to do the job.

If this is not possible you can remove most deck stains by washing the deck using a good quality deck stain remover such as Thompson's deck wash. Apply it with a handheld pump-sprayer. Closely follow the instructions and immediately use a pressure washer to remove old semi-transparent stain. Do not use too much pressure or it will damage the wood.

Another method is to dry-sand the boards. This is very labor intensive and makes a dusty mess. Sanders can be rented from most hardware stores. If your deck has a surround of handrails, spindles and flower-boxes the sanding will be even more difficult as a lot of hand sanding will be required.

The last alternative is to replace all the decking boards. This can get expensive but if this is your choice I recommend using composite decking to replace the wood. At least you will never have to be concerned with removing the stain again. If you are not into composite decking I recommend using mahogany. It is extremely durable and is impervious to insects. And it does not require any paint or sealer. It will turn a light gray as its ages but will look great for many years.
