I've stained my deck and its very slippery when wet from the weather. Any ideas?

Asked by: dee
Now it is weather protected. If you require slip resistance, there are other products available to solve that slippery issue but for now, that is what happens when a good product seals wood from weather. It will remain that way until it wears in and by that time, it will need t be re sealed.

1 gal. Semi-Transparent Acorn Brown Waterproofing Stain is rated 2.6 out of 5 by 40.
Rated 1 out of 5 by from Short lived... Worst Thompsons product ever. New deck, professionally built, cleaned, and dried. THREE coats of Thompsons and I was in love with the natural color and ease of application. As of today I have had to pay someone to pressure wash and sand down the few tiny bits left on the surface. The deck is 1 year old as of last week and this product has been completely gone for over 3 months. Will spend my July 4th weekend using a step ladder into the pool while they finish resurfacing my decking. Nothing on the deck but feet, no furniture to scratch either. Just seasonal foot traffic. I've literally had nail polish last longer. And our winters are mild here I Texas.

Put this down on seasoned (older) pressure treated lumber that has been stained regularly for several years. This looks RED (leaning toward PURPLE)! Don't know how you get "acorn brown" out of that, and looks more solid than semi-transparent. Will NOT buy this color again!

It did not apply even and you can see brush strokes. Water did bead up well, but is starting to come off after 8 months. Hopefully it all comes off soon, so I can try again with something else

Rated 5 out of 5 by from Easy to apply and works well We have always used Thompson's to stain and seal our redwood deck and protect it from the elements. We re-did our deck about 10 years ago and have now applied Waterseal to it four times and the wood is still as good as new, despite it's annual baking in the hot So Cal sun. Recently we decided to change the shade from the lighter Harvest Gold shade to this darker Acorn Brown shade to better match our cedar siding which is stained with a dark brown wood oil. The best part about this semi transparent style of Waterseal is that it has a decent color tint to it, yet you can still see the wood grain through the sealer, so it retains a more natural look on the deck once it is applied. The preparation work takes a while and involved power washing the old Waterseal off the deck boards (it had been applied 18-24 month earlier and had worn through in a few high traffic areas). Once the wood had dried from the power washing, we applied the new stain with a pump sprayer and a 2" chip brush. Clean up is easy with water and running water through the pump sprayer stops it getting gummed up with the Waterseal. Since we use the cheap 'chip' brushes from the paint department at Home Depot, we just throw them away when we're done, but water will also clean the brushes. I found that it is best to work early in the morning before the sun hits the deck as the Waterseal absorbs into the wood a little better and the instructions recommend not to apply it in direct sunlight. We use just over a gallon of Waterseal on our 36' x 12' deck. It is a couple of months since we did the job and the winter rains have recently started. The rainwater now pools on the deck boards like a freshly waxed car.

Rated 1 out of 5 by from Absolute garbage I have a 5 yr old deck, well seasoned. Pressure washed prior, and used Thompson's deck wash with stiff brush. Then pressure washed again. A little too solid for me , not as semi-transparent as I would have liked. The color was disappointing as well...but too late for that. Areas that seen the most sun lifted the most. Absolute disappointment. Now do sand the deck down and go with a quality stain, or take the chance and stain over this garbage? Not pleased....will be going back to HD to see if they stand behind products, or value their customers.

Rated 1 out of 5 by from HATE this product. I HATE, HATE, HATE this product! I used it two years in a row thinking it was a good quality product. I sealed my deck mid summer when it was dry. It looked beautiful all rest of the summer and fall. Once our Chicago winter was over, and the snow melted off, all the sealer peeled off, as if I had never stained the deck. The first time I thought it was a fluke, the second time I knew it was the product.

Rated 3 out of 5 by from Frustrated Background: deck built 3 years ago; boards shrunk due to no protection Process: power washed deck, sanded deck due to slight riveting from power washer, cleaned with Thompson's 3 in 1 cleaner, stained as directed Outcome: 1) deck color too orange; wanted anything but orange color; initially going to use maple brown, but used acorn brown to stay away from orange color; even applied second coat per instructions, but still orange 2) deck extremely hot to bare feet 3) water puddles on deck, opposed to beading; have to sweep water off deck after it rains as heat/sun/time does not dry up puddles 4) deck now slick; furniture slides easily; had to put rug under lounge chair to keep it from sliding when sitting down 5) deck also soft; waited 48 hours to put furniture on deck; sitting in chair was putting dents in the wood; put rug under chair to keep from marking deck Hints: 1) if you get stain on concrete, use Professional Strength Goof Off; comes with an open top, so you may want to try a spray bottle to apply; suggest going to a dollar store for plastic spray bottle and wire brush ($2 total); apply Goof Off, wait a couple of seconds (don't let dry); stain brushes right off 2) if you get stain on vinyl railings, use Goo Gone; apply Goo Gone and wait a little bit to let soak in, then wipe off; may take a little elbow grease, but found by letting it soak in makes it a lot easier to remove 3) apply stain in cooler weather; will make it a lot easier to apply; applied at 85 degrees in the shade; dried too quickly showing some overlapping Side Note: ants appeared in house after power washing deck; used Terro Ant Killer; after 2 days ants were gone!
