I will attest to excess pressure causing damage. There are some areas of my deck now that are furry for a lack of better word. I got a little aggressive trying to get the old deck stain off. I guess better late than never to learn the proper way.]]> Deck Stain Stripping Questions and Answers Barry Maddox https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7322 https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7321 Mon, 13 Feb 2012 15:24:13 +0000
Deck Strippers and Deck Cleaners are caustic cleaners that will raise the pH balance of the wood. This "darkens" the overall appearance. Wood Deck Brighteners are mild acids that neutralize the caustic in the wood, lowering the pH to a neutral balance. This step "brightens" the wood.

Never wash wood with just a power washer as excess pressure will cause damage to the deck.]]> Deck Stain Stripping Questions and Answers Scott Paul ~ Restoring Wood & Decks Since 1993 https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7321 https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7319 Mon, 13 Feb 2012 15:12:17 +0000
I wasn't aware of having to use a wood brightener but I will now that I know. It makes sense to brighten the wood back to the proper pH before sealing it. This helps a bunch, much appreciated.]]> Deck Stain Stripping Questions and Answers Barry Maddox https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7319 https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7317 Tue, 07 Feb 2012 23:26:58 +0000 deck stain stripper will "soften" the old coating so you can wash it off at a low pressure.

Make sure to neutralize the stain stripper with a wood brightener when done.]]> Deck Stain Stripping Questions and Answers Scott Paul ~ Restoring Wood & Decks Since 1993 https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7317 https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7315 Tue, 07 Feb 2012 21:11:06 +0000
I used water and pressure only. Is there something that will help me get the rest of the old sealer off?]]> Deck Stain Stripping Questions and Answers Barry Maddox https://forum.deckstainhelp.com/deck-stain-stripping-questions-and-answers/can-i-seal-over-an-old-stain/#post-7315
