Q. Can I apply patio coatings over an existing surface?
Can I apply patio coatings over an existing surface?
or do I need to remove the previous material?
1 Answer
Yes, you can - in most cases, anyway. While it is generally accepted to apply patio coatings over an existing surface without removing the previous material, the most optimal course of action in each case may differ depending on the condition of the existing surface.
If the existing surface is in good shape, then usually, there is no need for replacement. By good shape, I mean that there are no major defects on the old surface. If the surface is uneven, damaged, or cracked, then I’m afraid you may have to repair and level it before you proceed.
Another factor that’s important in this regard is the type of coating you are applying. Some coatings require specific priming and other preparatory steps.
So, in short, whether or not you can apply coatings directly over an existing surface is a question of the existing condition and coat type. The resource here has more information on the subject: https://epoxyfloorsocal.com/epoxy-fl...
