This product dries clear and provides a raw wood finish.** A: Sprinkle some water on the wood - if it still beads up then the product is still working. If it soaks in then clean the wood and let dry prior to a new application. I hope this helps. Norkan Inc. **Q: What is the coolest temperature outside that I can still apply this? Are the directions written anywhere online?** A: Seal-Once.com Don't use below 50 F . Be sure your wood is dry **Q: If you apply one coat to both sides of 3/4 plywood do I need a second coat?** A: Yes, Apply the second coat within 15 minutes of the first coat. You cannot apply stain, paint ,varnish or glue over Seal-Once products. They will bead up and roll off. Seal -Once products are for exterior use. Clear will allow the wood to grey naturally. **Q: Is nano best choice for new cedar boards supporting storage shed? boards rest on cinder blocks completely open to outside all around.** A: Nano is a great choice. Clear will allow the wood to grey naturally. Before application sand the boards with 80 grit sandpaper, nothing finer. That will open up the pores of the wood for deeper penetration. ## Frequently Bought Together - Seal-Once Nano Penetrating Wood Sealer - Premium Waterproof Sealant - 1 Gallon Clear Wood Sealant - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement - Linzer 3121 0400 Stain Waterproofing Brush, 4 in.,Brown,WM 3121-0400 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/41343254-nano](https://www.desertcart.es/products/41343254-nano) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-07-07*
