Stocked at our Milwaukie, Portland and Vancouver WA yards — with delivery across Oregon & SW Washington. Pricing is free and there’s no obligation.
Coverage rates vary by brand, application method, and wood porosity. These estimates use industry-standard rates ± 15%. Always buy a little extra — tinted stains can't be color-matched exactly on a second purchase.
