TWPStainHelp.com Tips: It Rained on my TWP and How to Fix

When applying TWP Wood stain to an exterior surface, it can be a battle with Mother Nature to find an adequate weather window. With TWP Wood Preservative it should not rain within 12 hours after applying. The stain may not be affected by a little rain especially if it has soaked into the wood already. But in the case of significant rain, it can have an effect on the stain’s appearance.

If it rained on your TWP and you want to know how to fix it here are some tips. After getting rained on still allow the surface to dry for at least 24 hours. Only then will you be able to see the extent of the damage. Because water and oil do not mix, the rain may not affect the appearance as badly as you think.
Once the surface has dried check to see if the finish looks spotted, blotchy or uneven. If it appears the rain did affect the finish, you can lightly wash the deck again as you did prior to staining it. You can use a mild detergent but you are just trying to even out the finish. Don’t wash it too aggressively. If a little TWP comes off that is fine because you are probably going to have to reapply a light coat regardless.

If a light wash is not working to even the finish you may have to do some sanding. You can also use a deck stain stripper if you are unhappy with the results. After cleaning or sanding the affected areas, allow the deck to dry again for a day or two.

Once dry, reapply a light coat of TWP Stain. Only apply as much stain as the wood will absorb. Do not leave excess puddles on the surface; wipe them away with a clean cloth or brush. Try to even out the finish as best you can by back brushing.

These tips should help you fix the problem of rain on TWP stain. In extreme cases, the entire surface may have to be stripped or sanded and completely re-stained. Always check your local forecast before starting a TWP wood-staining project.

I’m applying my maintenance coat of twp 100 today. Possible rain in less than 24 hours, could I cover with plastic 8-10 hours after application to shield from any rain overnight?

I applied one coat to a deck that was stripped. The wood did soak up the stain. Rain did bead on the surface, but should I apply a second coat now (2 days later)?

Is it normal for rain to puddle or pool on a newly stained deck? We stained our deck with TWP 1500 and it rained about 5 days following staining. I’m just wondering if we should sweep the water off or let it evaporate. Also, we are prone to snow, should that be removed and if so, will shoveling damage our stain?

We live in Colorado and after a year of weathering finally got to stain our redwood deck for the first time. After applying and wiping off the excess, it looked fantastic and ready to dry. 25 hours later, we got a pop up rain that is significant and lasted a couple of hours ver night. Can we wipe off the water to keep it from leaving spots when it dries or are we just at the mercy of the weather and hope it is okay? Now they are predicting 30% chance of rain for the next 2 days.

My deck is 8 months, old because we live in the smoky mountains moisture is an issue and mold.
The deck is showing small spots of mold. How should I clean it and what series is recomended.

I used TWP after good surface prep on our deck; then, it rained two hours after the second coat (i.e., wet-on-wet). The rain was significant yet still what would be moderate for Kansas and lasted all night. The water beaded up as one might expect. I expected a disaster because the directions call for 48 hours of dry weather after application and we were lucky to have two hours. The next day it dried briefly and then rained again. The water beaded up like before. After it dried (i.e., at least the water dried), the deck looked good. No spots… Read more »

You would have to strip it all off and start over now. Adding more will not fix the issue.

Thanks

Good Afternoon, I had me new deck stained last week, but just as they were finishing the base of the deck, it rained! It dried all spotty, so they cam back, and re-sprayed it, but I think it looks worse now, very uneven. What can I do to make it better?
