I got a job coming up at the end of the week to wash, re sand and seal a backyard interlock patio.
It’s a fairly new patio, but the customer has had quite a few parties on their patio since it was installed and it was never sealed. That being said, the amount of food stains, BBQ grease stains and random drink stains makes it look like it’s 20 years old. I was thinking about pre-treating with a degreeser such as super clean, letting it sit for 15 mins then hitting it with the surface cleaner.
I don’t wanna go through the process and the stains not come out.
Any tips or tricks??
