My elderly relative has me apply 2-3 extra heavy coats of Thompson's Water seal to the porch every year. The problem now is that it feels like we're walking on oil. Every time the porch gets wet it's impossible to walk on...any advise?

    Sand it off and reapply but not so often. From what I read no more then 3 applications total. But the key before applying water seal is to sand the deck not just pressure wash it.

    turpentine may take some of it off. i just spent the last 4 days with my elderly retaliative applying deck sealer. turps was what was suggested for clean up.

    Rent a large sander and save your back!

    Too much water seal is not good either so back off on the applications. Once at the beginning and maybe every 4-5 years after that should be good enough.
  • Yup, older folks think if some is good, more is better. If it were me, I would obtain a few consults from local contractors to explain to them that more is not better. May I suggest, since you are dealing with elderly relatives, invest in some good quality porch mats. I swear by these.


    Certainly not cheap, I bought my first one years ago from L.L. Bean, now more widely available, even some Home Depot stores carry a limited selection. The safety of you and your relatives is worth it v. slipping, falling and resulting injuries and hospital costs.

    It absorbs into the wood grain. Too much and it does absorb completely and it can migrate back to the surface. Only put on what gets absorbed. You can remove what you have on there with mineral spirits. I would be weary using turpentine as it is a carcinogen and would also absorb into the wood and affect the wood.
