Tricia Craven Worley: I’m admiring the old brick in this area of the patio that we recently redid. It was damaged by a storm, and as you can see it’s all mortared in concrete.
Now concrete, which is certainly used for a lot of patios, and in this instance for the mortar, it needs to be sealed. But before you seal it you want to let it cure for about 30 days.
Now the rest of the patio here is done in a flagstone, and this has been down for about 70 years. But doesn’t it look new? That’s because it was just recently cleaned.
Now, we cleaned it with a muriatic acid, which is highly corrosive, so you want to be really, really careful when you use it and follow the instructions. But after that it is important to seal the patio, and we’re going to do that with a clear sealer.
Regardless of what kind of product you use, it’s generally a porous product—whether it’s some kind of stone, concrete, or brick—so you’ll always want to make sure that you’ve sealed it properly.
And this is something that I choose to do about every two to five years on my patio to keep it looking the best it possibly can.
