What happens if it rains after applying Thompson's Water Seal?

Last Updated: 3rd April, 2021

Rain will damage the finish of any wet sealer with linseed oil or mineral oil in it. Because it forms a coating, it takes several hours to "set up" (dry) and during that time the sealer is vulnerable. If the surface dried enough to touch and the rain was gentle, you may find no problem at all.
