Subject: deck repair/rebuild
Date: Tue, 26 Mar 2002
I've read your questions and answers - very informative, but they seemed to hit all around my question, so here it is... I have a large area of outdoor deck (typical "treated" 5/4 pine boards) that is severely damaged from too much pressure washing and not enough UV/water protection over the years. The boards are basically in good shape, but the surface is badly splintered, split, etc. Can this be coated with a product that will re-build the wood to a new, smooth surface, and then stained/painted and protected (or an all-in-one application)?
From your description, I would say that probably the most thorough
approach would be to machine sand smooth, vacuum clean, apply a couple
of layers of our ELASTUFF 120, and then over-coat that with the RHINO
TOP. This would give you a smooth, totally waterproof deck coating. The
deck would be opaque, not woody-looking, but attractive stained decks
are a constant maintenance headache.
Depending on the size of the deck, this can be a relatively expensive
solution, with ELASTUFF 120 running $157.18 per 2-gallon unit and
coverage at only about 100 sq ft per gallon. The RHINO TOP is a little
better at $40.69 per gallon and coverage at 200 sq ft per gallon. I
should mention too that two coats of each are required. But it's a
one-time solution, with future maintenance being only touching up the
RHINO TOP when necessary.
The ELASTUFF 120 would fill all shallow grooves and cracks. Once cured
it can be sanded if you want a REALLY smooth decks, but I think that
between two coats of ELASTUFF 120 and two coats of the RHINO TOP the
deck would emerge reasonably smooth. Details on both these products are
on our website, and you should come back if you have additional questions.
An alternative would be to go through the sanding/vacuuming process,
treat the wood with our CPES (Clear Penetrating Epoxy Sealer), fill all
cracks and voids with Fill-It Epoxy Filler, and then paint with any
standard "porch" paint (or the RHINO TOP). CPES coverage would be around
150-200 sq ft per gallon, and the Epoxy Filler would be a volume issue
-- enough to fill what needs to be filled. In this alternative, the CPES
would protect the wood from rot and deterioration, and the opaque paint
would protect the surface from the UV degradation. This would be a
"weather-proof" solution, in that the Epoxy Filler would not crack or
pop out under changing weather conditions.
Unfortunately there are no really effective clear coatings available
that will protect the WOOD surface from UV light damage -- except
marine-grade varnish, and this would be a path you don't want to travel.
The normal deck sealers are petroleum-based and some have
micro-particles to protect the wood from UV light, but the petro bases
gradually degrade and coating usually has to be done at least yearly.
And the decks turn dark and unattractive, so that means power scrubbing
with TSP/warm water before each treatment. Petroleum-based products also
promote the activity of wood-destructive bacteria.
Hope this has been of some help. Come on back if we can answer any questions.
