A great option for a solid painted look on deck floors is Sikkens Rubbol Solid DEK, which is a flexible, breathable hybrid oil / water floor coating
(not a paint).. It looks like
paint, but performs like a stain--no film to peel when properly applied. .
It is breathable and flexible when applied to bare
wood. Will require maintenance more frequently if in direct sun.
We also like California Coatings Enduradeck Solid Color Acrylic Floor Coating System for many projects. The Acrylic makeup gives this coating excellent satin sheen and color retention.. It offers excellent adhesion to properly prepared surfaces that have been previously coated. Enduradeck is flexible and breathable and is a great choice to consider when coating exterior wood decks and flooring when a solid hide stain is desired.
Previously Coated Wood
The following discussion explains reasons we should consider sanding wood for best results with any stain or finish when wood has been allowed to weather in the elements, or if a previously applied coating has failed. Sanding opens the pores of wood to accept stain, and also removes loose or deteriorated wood fiber that generally leads to premature coating failure and poor results. Sanding can also be utilized to blend or remove remaining stain after the deck stripping process.
After using strippers, many times wood is "fuzzed" and should be sanded using 80g sandpaper following the stripping process.
For potentially dangerous sanding dust, use paper disposable dust collection bags,
and dispose of properly. Use only vacuum capturing sanders, and sweep and wipe clean all surfaces immediately after sanding. Pets and family should not be exposed to sanded surfaces until wood is sealed and protected.
Sanding will usually increase the adhesion and performance of your coating system. Use Dust-Free Deck Sanding procedures, and use all precautions with any potentially dangerous sanding dust. Exotic hardwoods like Ipe and brazillian cherry produce quite hazardous dust as well.
Use caution when working with CCA-treated lumber.
Avoid sawing or sanding, which releases arsenic into the soil and air. If you must sand or saw, do so only outdoors with plenty of ventilation. DO NOT ALLOW CHILDREN or Pets TO ENTER OR STAY IN THE AREA! Wear dust masks, gloves, and protective clothing to decrease exposure to sawdust and wash all work clothes separately before wearing them again. Sand only utilizing proper dust collection and disposal methods. Consumers should follow manufacturer recommendations when handling the wood, including the same precautions that workers should take: wear gloves when handling wood, wear goggles and dust masks when sawing and sanding, always wash hands before eating, and never burn CCA treated wood.
SANDING DECK SURFACE
Even NEW Wood, many times, needs sanded due to "mill-glaze" resulting from the planing and smoothing process at the sawmill , which compresses wood fiber, and polishes new wood making coating penetration virtually impossible. Wood that has weathered unprotected while drying over the first few months after installation should be sanded as well to remove weathered surface.
Norton's 3x series paper is also designed for coating removal. The paper really does make a difference. The 3X resists gumming when sanding existing stain or coating.
Most floor coatings will recommend 80g or 60g bare wood sand, but it depends on the coating you choose. We use a Dust-free Palm Sander. We always do a final brush vacuum prior to coating application, and wipe the surface to insure no dust can interfere with coating absorption and adhesion.
