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.

Keeping this in consideration, how long does Thompson Water Seal take to dry before rain?

When to Seal Your Deck The forecast should indicate no rain for at least 24 hours after application. The deck surface should be allowed to dry for at least 48 hours before application.

Also Know, can Thompsons Water Seal be sprayed on? Answer: The manufacturer of Thompson Water Seal recommended that you use their product with a plastic sprayer with a brass wand, such as our Chapin Premier sprayer. Once you are done with the product, it is recommended that you run mineral spirits through the sprayer and then water to clean it.

Similarly, it is asked, how long should deck paint dry before rain?

If you are using latex acrylic paint you need at least two hours of sun for exterior paint to dry before the rain comes. If heavy rain is forecast or several days of rain are coming in the next few days, you will need about six hours of good sun to dry the paint thoroughly enough to not be affected.

Will rain ruin a newly stained deck?

Because it becomes a part of the wood, stain lasts for a long time if you apply it properly. This means applying the stain on a day when rain is not forecast for at least 48 hours. Rain on a newly stained deck can ruin it.

Does primer protect wood from rain?

However, on other surfaces, such as wood, it is less durable and weather-resistant than water-based paint. After applying the primer, wait until it is completely dry before you apply your chosen exterior paint. Finally, you should never try to apply exterior paint in the rain or when rain is in the forecast.

How often should you seal a wood fence?

Many experts recommend every 2-3 years, but a better way to determine your need is to check for beading. On a stained and sealed fence, if water no longer beads up on the surface, but instead soaks in, it may be time for maintenance. Check painted surfaces for cracks, chips and wear.

Can you use a pump sprayer to apply Thompson's Water Seal?

A pump sprayer, sometimes chased by a pad, is the usual recommended method for applying sealers and at least semi-transparent stains. I am not sure you will get the coverage you are seeking through regular spray gear. And again, if you go with Thompson's you will have the wax issue in your spray system.
