Does it make the fabric waterproof. Yes it does.
We needed to wait for good weather to apply the sealer and we did complete the cover on our gazebo. Since applying we had the storm and the fabric coped very well. Thank you

Easy to apply and dried quickly
Easy to apply and seems to work well. I applied 2 coats to a jacket, but the second wasn't really required and just ran off the surface.
