About our coating
LS Pro Formula | Semi-Transparent Series
LS PRO is a heavy-duty, plant-oil-based, waterborne, penetrating stain designed specifically for rough-sawn exterior siding, mass timber, logs, cedar shingles, and other highly porous wood surfaces. Engineered for superior adhesion and deep fiber saturation, LS PRO delivers long-term UV protection, water resistance, and color longevity across a variety of architectural applications. LS PRO has a rapid first coat absorption rate of 10 minutes(under ideal conditions) enabling quick turnaround for prestaining machines or dynamic operations.
While LSS performs exceptionally well on its own, prior to staining, one can apply Internal Wood Stabilizer (IWS) or Ember Guard (EG) beneath LSS for enhanced pigment durability, dimensional stability, rot prevention, pest deterrence, and Class A fire resistance (EG).
• Professional durability on rough, aged, or textured wood
• 10 min deep-penetrating stain
• Designed for long-term performance in extreme exterior conditions
• Non-toxic, water-cleanup, and ultra-low VOC
• Protects against UV degradation, moisture, and mildew
• Available in 70+ tones with custom color matching available
• Compatible with EG, IWS, and CU (interior) for enhanced performance
• Recoatable without sanding if maintained
• Rough-sawn: cedar, fir, pine, hemlock, redwood, specialty wood substrates, etc.
• Mass timber; commercial, residential
• Interior wood surfaces: beams, log siding, rough sawn feature walls, etc.
• Exterior wood surfaces: beams, log siding, cedar shakes, shingles, etc.
• Plywood, OSB, Cork siding and other specialty wood substrates etc.
• Weathered or restored exterior wood
• EG + LS PRO for Class A fire resistance (ASTM E-84), moisture resistance, longevity, and aesthetic durability
• IWS + LS PRO for superior stability, moisture resistance, longevity, and aesthetic durability
• Crystal Urethane + LS PRO for wipeable high touch interior surfaces
LS PRO is intended for raw or properly prepped rough-sawn wood surfaces. Not intended over surfaces previously coated with non-penetrating acrylics, latex, solid paints, or oil-based products still resisting water. For optimal results, use LS PRO on raw wood surfaces(kiln-dried or air dried, moisture content <14%).

"Highly recommended!"
I used the Internal Wood Stabilizer on the interior of our cedar raised beds. It's an excellent product - the best food-safe waterproofing treatment that I could find. The exterior was sealed with Timber Pro UV's Deck and Fence sealer (Honey). Excellent customer service!! Knowledgeable staff and fast shipping. The best green products available!

"Remarkable product and service!"
Super friendly and knowledgeable and helpful staff at the store. Gave me samples to try at home and made ordering our choice product easy over the phone. Worked with us and our contractor to ensure we had the right product (fence stain - Tamarack) ready for our fence project. An incredible experience with a local business. Very very happy with our results.
