Before you re-stain a deck, there are a few steps you should take to prepare and get the deck ready to absorb the new color. If this is the first time deck stain color is going to be applied to the surface of your deck, you’ll have slightly less prep work to do. For those who have a deck with stain already applied, there is the extra step of making sure that the old color is removed before you start.
Step One to re-stain a deck
Start by looking over the condition of the deck. Make sure there are no loose nails or rotting boards before you start trying to re-stain a deck. Check the boards for signs of splintering or rot. Fix any issues you find before you proceed with staining the deck.
Step Two to re-stain a deck
Remove any existing deck stain color using a paint stripper or sander. Make sure the paint or stain is uniformly removed from the wood surface and no patches remain. This will help your new stain look the same across every part of the deck. Once all of the color is removed, you can proceed to cleaning the deck.
Step Three to re-stain a deck
Use a wood deck cleaning product along with a pressure washer to clean the deck. Dilute the cleaning solution as specified on the product package and wait until a day where the wind is low and no rain is forecast. As you wash the deck, use the lowest pressure setting on the washer to avoid damaging the surface of the wood. Using a wide spray across all of the boards will help you remove all of the dirt. Allow the deck to dry overnight before you proceed to sanding the deck.
Step Four to re-stain a deck
Once the deck has dried, you may see more splinters and rough patches along the surface than before. This is due to the pressure washing and the normal expansion of the wood as it dries. To get the wood surface smooth again before you stain it, use a power sander to sand the planks.
Step Five to re-stain a deck
Select the new stain color and finish for your deck. Use a high quality bristle brush to apply the new stain onto the small areas, such as the hand railings, stairs and built in shelves. Work your way down these areas from top to bottom to avoid any drips appearing in the finished product.
Step Six to re-stain a deck
Wait 48 hours before you stain the surface of the deck. This will give the planks time to dry and be ready to absorb the stain you apply. If the deck gets wet due to any rain, wait another 48 hours to allow enough time for the water absorbed to dry. Use a paint pad to apply the stain in wide, even strokes on the deck. Allow the first coat of stain to fully dry before you decide whether or not to apply another coat.
Once these steps are completed, your newly stained deck will be ready to enjoy. Over the first few months, the color of your deck may change slightly as the stain settles. You may choose to re-seal the deck a few months later to prolong the life of the new stain.
