This is the 2nd time using Seal tech and they haven't let me down. MY neighbour has a very large Norwegian spruce tree in there backyard and it sheds a lot of sap and pinecones that over time fall on my side and discolour the natural stone I paved.
Seal tech actually came twice this summer because the first time it started raining just after they had sealed the stones and it left white marks a little everywhere.
Thank you for coming back a second time to apply a thinner to melt the seal so that it would look new again.
I will be calling seal tech in the future for my pavement needs and are a professional company to deal with.
