Live in Georgia
Deck gets almost full sun from about 11:30 to 4:30 - partial shade otherwise
3 Year old deck
I believe pine that was allowed to cure 6 months before staining
Having problems with both peeling and mildew/ mold
Stained with a semitransparent. Got the color home and were not happy so brought it back to Sherwin Williams and they first said cannot be altered but then said "lets try this" ... Not sure how they "altered" it. But now wondering if they didnt screw up the matrix by doing so.
We do have 2 dogs that will often horse play on the deck. However, they do not horseplay on the hand rails that are also experiencing peeling and mildew/mold.
You will see in pics a section that we tried to sand. Wood is in good shape but oh the work involved. Have had 2 quotes from deck companies. One wants to strip with solvent the other wants to lightly sand off only the peeling parts and solid stain over.
Question- Best way to remove the old stain.... do we need to remove all of it? The goal is to not have mold issues and NOT have peeling issues AND to simply be able to reapply fresh stain every couple years. EASY maintenance with no issues please. Am I asking too much here?
And lastly... is it possible to use a semi transparent once removed? Is it true that there are less issues with semi transparent than with a solid?
Thank you so much for your help!
Whatever they did, they made it into a solid stain. The only way to get what you would like to do (easy future maintenance) and use a semi-transparent stain is to power sand it all off.
Yes that is what we were afraid of.
3 more questions.
1.Is it true that there are more issues with solid stains in general as far as peeling and mold than with semi transparent?
2. What grit sand paper do you recommend? We have tried a 60 grit but it took so long. Wondering if it is ok to go with a more aggressive paper?
3. If we decide to stay with a solid stain how would you recommend prepping the existing deck for best results?
1. Yes
2. 60-80 grit. Rent a drum sander.
3. Use a stripper and pressure washer to remove the loose stain and then cover over the intact stain with a new solid stain.
