Anything to paint the underside of the deck with?

[o---o]

I'm worried about my deck rotting from the underside up. Is there anything good to paint the underside with to help prevent this?

The best prevention is don't mow wet grass and clean the underside of it often--without water. I recommend a plastic putty knife and an air hose to shoot air over it. I have always used the rubberized undercoating in the automotive section for painting the underside of decks and never had one rot on me after having done this....but then again, I have only owned cubs for 14 years at this point. Others will chime in and have other suggestions that will be more helpful to you than what I have stated.

Thanks. I was wondering how well it work to have a spray in bedliner professionally applied?

I would think rubberized undercoatings and bed-liners will be too abrasive or "sticky". The underside needs to be smooth so the grass will discharge. Kind of like trying to scoot something on a pickup bed with no bed-liner as opposed to one with.

Best thing is epoxy primer with a good layer of paint. Then do as suggested, keep it clean, and dry.

Thanks I'll give that a try.

Slip plate/graphite paint. Slick and smooth, the same idea as snowthrower surfaces.

I pull the spindles, pressure wash it good, coat the underside with rust neutralizer, brush on a few heavy coats of Rustoleum paint and then a few coats of Slip Plate.

The best way to prevent rust is to get the underside of the deck as smooth as possible, this means no bedliner or anything else with texture. The more texture you have the more grass will stick to it, a nice smooth paint job works good and will prevent large amounts of grass from collecting under the deck. Gloss paint only, flat paint in porous and allows moisture in where gloss paint is sealed.

I had some extra POR15 from another project and it has held up great. Hardens up slick and shiny.

I always thought that if glues stuck as well as the grass to the underside of a deck life would be much easier.
