Sansin Protect-A-Cut

Sansin Protect-A-Cut is a ready-to-use, water-resistant treatment formulated for the freshly cut ends of pressure-treated or untreated lumber. This ultra-low VOC coating protects exposed end grain from moisture ingress, decay, and warping while helping to maintain dimensional stability. Available in Clear, Brown, Green, and Gray to match most pressure-treated lumber finishes.

Protect-A-Cut is ideal for contractors, builders, and homeowners working with decks, fences, posts, and other exterior wood where fresh cuts expose untreated end grain. The easy-to-apply formula bonds quickly to wood fibers, enhancing long-term durability and minimizing the risk of end grain failure.

What Makes Protect-A-Cut Unique?

Unlike standard wood coatings, Protect-A-Cut is designed specifically for end grain application, which absorbs significantly more moisture than face grain. Its water-repellent, ammonia-neutral formula penetrates and seals the vulnerable cut ends of treated or untreated wood, providing broad-spectrum rot resistance. With no harsh solvents and soap-and-water cleanup, it’s also safe and easy to use on-site.

Key Benefits of Protect-A-Cut

• Seals freshly cut end grain to prevent water absorption and decay.
• Ultra-low VOC formula with less than 5 g/L—environmentally friendly.
• Available in four tones to match pressure-treated lumber or clear wood.
• Fast-drying and easy to apply with brush, dip, or spray.
• Improves wood stability and minimizes end grain checking.
• Water-based for easy cleanup and safe use around homes.

Application Notes

• Surface Preparation: Apply to freshly cut wood ends. Ensure surface is clean, dry, and cool to the touch. Do not apply to hot or wet surfaces.
• Tools: Apply with brush, low-pressure spray, automated spray, or by dipping the wood into product for 30 seconds.
• Working Conditions: Ideal temperature is 21°C (70°F) with 50% relative humidity. Do not apply if rain or freezing temperatures are expected.
• Mixing: Stir well before and during use. Do not shake.
• Coats: Apply 1–2 coats. For added protection, apply second coat within 1 hour of first.
• Dry Time: Dries to the touch in approximately 30 minutes at 21°C and 50% RH.
