You are probably asking yourself this question, do I need to remove old stain before restaining a deck?
Yes, it would be best if you stripped, remove the old stain before you restain. If the stain on the surface of your deck is old, worn out and peeling, the first thing you should do in your quest to renew the deck is to remove all the old stain.
Solid deck stains offer much-needed protection to the wood. Besides, it looks incredible when new, as you’d expect, with time the stain flakes and wears away.
How Can I Tell Whether My Deck Needs Stripping Before Restaining?
- Previously Stained Using Solid Stain
If you had initially coated your deck with a solid deck stain and you want to determine whether or not you should strip the surface, use a sharp blade to cut a small light ‘X’ in several spots on the surface of your deck high and low traffic regions. Avoid cutting the surface of the wood.
After cutting those ‘X’ marks, use duct tape to cover them and rub down firmly. Follow this by a quick peeling of the tape. If you see flakes of the stain on the tape, you will have to strip your deck before you restain. You can use paint strippers for wood to remove the stains.
- Previously Stain Using Semi transparent Deck Stain.
If previously you used a semi transparent deck stain in the coating of your deck, you need first to clean it thoroughly and allow it to dry in the air for four hours or more.
Follow the above procedure by pouring a small amount of water on areas of high traffic of the deck as well as areas that see less traffic. If you notice the water beading up (burst into tiny drops) then remains there, it means there’s a lot of stains, and you will need stripping. If you notice the water remains in a puddle then starts to absorb into the wood in 10 minutes or less, then it means the layer has worn off enough for you to restain without necessarily stripping.

Step Three: Staining of the Deck
