ARBORCOAT is powered by the same patented Gennex waterborne colorant technology developed by Benjamin Moore over the past decade. It is a system that not merely has yielded award-winning low- and zero-VOC interior paints (Aura and Natura, respectively), but has dispelled every argument that performance is sacrificed or compromised by going “green.” In fact, in divining the new Gennex formulations, Benjamin Moore has defined a new generation of paint, creating unparalleled ultimate performance coatings. Now, leapfrogging into the future, it’s doing the same for the stain category, delivering a low odor/ low-VOC product that’s well below the strictest VOC regulations yet astonishingly superior in performance to conventional stains.

Product Description

A premium quality 100% acrylic semi-solid stain formulated to penetrate and protect wood, resist abrasion, and beautify wood decking, siding, fencing, shakes and furniture. Its colors are semi-solid, allowing some of the color and the grain pattern of the wood to show through. ARBORCOAT Semi-Solid stain can be top coated with ARBORCOAT Waterborne Protective Clear Coat (636) for a low lustre look.  We have provided you with the Arborcoat Color Guide.  Each color has a sample of what it would look like with semi-transparent and semi-solid so please look at the right one for the Arborcoar Semi Solid color.  Please remember that all colors will look different through a computer monitor and even more different on different types of wood.  For any questions on color please call us at our toll free number: 1 (800) 457-1332.

How to Prepare Exterior Wood for Staining

Whether you are doing the job yourself
or hiring a contractor to do the work, you should have a thorough understanding of the staining process. The following information offers some guidelines for preparing your home’s exterior wood surfaces for staining.

The best time to stain your home’s exterior, deck siding, or outdoor furniture is when temperatures are moderate (above 50°F, but below 95°F), the humidity is low to average, and there is no rain in the immediate forecast. Ideally, you should have three to four consecutive dry days prior to beginning any exterior staining project.

Tools for the Job 
Benjamin Moore offers a complete line of brushes and rollers designed to work with wood stains. Alkyd or oil-based stains should be applied with natural-bristle brushes. Synthetic-bristle brushes are ideal for latex or waterborne wood stains. The following is a list of tools and supplies for exterior staining projects.

  • Stain brushes or pad applicators
  • Benjamin Moore rollers and roller covers
  • Stain mitt
  • Sprayer
  • Caulk
  • Gloves
  • Hose or power washer
  • Paint scraper
  • Painter’s tape
  • Rags
  • Sandpaper
  • Wire brush

Surface Preparation
To achieve the best results, be sure to take the time to properly prepare the surface to be stained. As with paint, proper preparation is the key to a successful staining job that will last. See the following categories to find which best describes the condition of your wood, and how to prepare it for staining.

  • New wood – “mill glaze” is found on new, smooth planed wood, and interferes with the adhesion and penetration of stain. Use Benjamin Moore BRIGHTEN Brightener and Neutralizer (317) to remove the mill glaze found on all new wood.
  • Unfinished wood – Use Benjamin Moore CLEAN Multi-Purpose Cleaner (318) to prepare wood for staining. CLEAN removes mold and mildew.
  • Maintained finished wood – Use Benjamin Moore CLEAN Multi-Purpose Cleaner (318) to keep stained surfaces looking crisp as well as to prepare for regular maintenance touch-ups.
  • Mildewed/neglected wood – Use Benjamin Moore RESTORE Wood Restorer (316) to remove dead wood fibers and for cleaning. Please note that Benjamin Moore RESTORE darkens tannin-rich woods such as cedar and redwood. UseBenjamin Moore BRIGHTEN Brightener and Neutralizer (317) to reverse the darkening effect.
  • Worn/stained wood – Use Benjamin Moore REMOVE Finish Remover (315) to remove existing oil and/or latex finishes as well as to remove opaque solid color stains and water sealers from wood prior to refinishing or restoration. Use Benjamin Moore BRIGHTEN Brightener and Neutralizer (317) to neutralize Benjamin Moore REMOVE residue.
  • Tannin-rich woods (cedar, redwood) – Use Benjamin Moore Alkyd Primer (366) to control tannin bleeding when using solid color stains, particularly under lighter colors.
