Old TREX DECKING Solution For Mold Prevention

This might be a solution to mold and other issues that TREX have.

[@chuckhooper5215]

Nothing have ever worked on my 20 year trex . I’m considering painting it this year and then replacing next if it’s not good. 52x12 and it’s been a night mare since installing. Yes it’s never rotted but it’s a weekend of maintaining every year with power washer.

Try 30 seconds outdoor cleaner on the TREX decking and railing at beginning of spring. Spray it on and in two minutes rinse it off, works like a charm. I tried it this year by accident and from now on I’m doing it every year.

What’s with the beeps. Had to bail.

If you didn’t use sodium hypochlorite to kill the growth in the board then you just sealed it in

[@stevedrago6935]

what did you use to get the mold off? just pressure wash?

[@Pauls-workshop]

yes

I have the same style/color Trex decking (18yrs old) Just power washed it today ...how did that sealer hold up?

[@Pauls-workshop]

Nothing changes, feels like sealer didn’t have any effect on the decking

[@probuilder961]

@@Pauls-workshop I actually found & applied some composite decking sealer by Defy & it seems like a quality product. I'm hoping it will dlow mold growth. Time will tell.

Did it work well?

[@Pauls-workshop]

Nothing changed, got just as dirty as before, I will not seal it again
