After following our recent twips you have done the right thing and taken the necessary steps to apply dampproofing paint to your basement. Now, a question you might have is when to reapply the paint for maximum protection. Most dampproofing paint is guaranteed for at least ten years between treatments. If your home is built near extremely damp environments, like marshes, your dampproofing will not last as long. In some environments you might have to replace the dampproofing every year. Finally, the time between treatments depends largely on how well the job was done the first time. The more professional you are in your approach to dampproofing, the longer the treatment will last. If you’ve only done the basics to protect your basement, you’ll have to do them every year.
