    Questions & Answers

    What is the maximum time I can wait before applying the 2nd coat? I had several days of bad weather before applying the 2nd coat. Can I still do that now?

    Answer This Question

    Hi Jesse, thanks for your question. We recommend applying the second coat within 72 hours of finishing the first coat for the best results. If it's been longer than 72 hours, I recommend testing the second coat on a small area first. Enjoy the rest of your day! -Christina

          We used Behr Hi Glass exterior water base paint on our deck 5 years ago. We have pressure washed the deck. Can I paint over the existing paint. The color is white on the deck and it is glaring with the sun. Will Cape Cod Gary solid color not be glaring?

          Answer This Question

          Hi Nadine, thanks for the question. You can paint over the existing paint with our Solid-Color Waterproofing Stain & Sealer. If the existing paint is glossy, I'd recommend scuff-sanding it first with 150-180 grit sandpaper. Also I'd recommend cleaning the surface with our All-In-One Wood Cleaner before applying the stain. If you have additional questions about your project, please reach out to us directly. Our customer care team is happy to help. -Ronald

                    What Customers Say
                    Summarized by generative AI from text of customer reviews

                    Customers say that the Behr Premium Semi-Transparent Waterproofing Exterior Wood Stain and Sealer offers good coverage and is easy to apply, often requiring only one or two coats for optimal results. However, many users noted that the color, particularly the redwood shade, tends to appear more orange than expected, which has led to some dissatisfaction. While the product performs well in terms of waterproofing, its durability on horizontal surfaces has been a common concern, with reports of peeling and the need for reapplication within a year or two. Overall, customers appreciate the ease of cleanup and the quality of the finish, but there are mixed feelings regarding color accuracy and longevity.

                    Better than Semi-Transparent
                    I have a redwood deck that needed staining from several short lived applications of semi-transparent stain. The semi did not last long. I sanded with the Mouse after filling cracks and feathering out dents. End result was the deck looks new. Hope it lasts in the sun.

                      Waste of time and description doesn't match product
                      Worst stain ever because it literally doesn't even match the description of semitransparent!! It looks like paint and the color is hideous. I used ready seal redwood semitranparent. The ready seal is still wet but look at the difference with one coat. Behr wasted my time, should've stuck with my go to ready seal stain but home depot doesn't carry in store.

                      Hi Holiday, thank you for your review. I'm sorry to hear that the color and finish did not turn out as expected. I can understand your disappointment. Our Cedar Naturaltone ST-533 will not match the Ready Seal Redwood color. Please reach out to us directly if you need further assistance. Our Customer Care team is happy to help! -Giovanna Behr
                        Not quite what I hoped for
                        I don’t love it. I mean I love the photos from other reviewers on the color cordovan brown but mine doesn’t quite look the same. It’s pretty thin and this photo is two coats on pine. I would call this transparent not semi transparent.
                        by
                          This product was for touchup. Color matches both water based and oil based stain. I suggest if you used oil based you continue using oil based or if you use water-based, you continue using the water base because the shades are almost the same.

                          Hi Xj538, thanks for your review. I'm sorry to hear about the peeling on your projects. To fix this, I recommend sanding to remove the loose stain, cleaning with our All-In-One Wood Cleaner to open the pores of the wood and promote adhesion, and applying two new coats of stain following the spread rate. Ensuring our customers are happy is our top priority, and we are eager to help get your project back on track. Please feel free to reach out to us directly for any additional support. We look forward to hearing from you! -Christina Behr

                            A nice color and easy application. It looked like Home Depot orange with the first coat but darken with the second coat. It has only been a week and happy with purchase , for now.

                              Stain is Peeling on Deck. Bad Quality Stain.
                              We bought this stain and hoped it would protect our deck and add beauty. However, the stain is peeling and is no longer protecting the deck, and it definitely isn’t looking nice only 6ish months later. We spent so much time following instructions to properly apply the stain, following drying and application instructions. However, it is still peeling and looking pretty bad. This is a bad product and we wished we had used a different one.

                              Hi Kris123, thank you for your review. I'm sorry to hear that our stain started peeling in less than 6 months. We understand your disappointment since the product did not provide the 4-6 year life expectancy. Customer satisfaction is very important, and our Customer Care team is on standby and ready to help. Please contact us directly so we can further assist you with a resolution. In the meantime, the issue can be fixed by removing the remaining stain by scraping, sanding, or using a power washer at a low setting. From there, you can clean with our All-In-One Wood Cleaner, followed by two coats of stain applied according to the label directions. Again, our Customer Care team would like to hear from you to see how we can help. -Ronald Behr

                                  I have used the Behr stain for vertical surfaces for years. It is the perfect redwood color. This stuff looks nothing like that nor the color on the can. It is basically orange and glows in the dark.
