Pre-treat Concrete

Does anyone pre-treat driveways, sidewalks and walkways with their mix before using their surface cleaner? Also if you do pre-treat what mix are you using, and at what ratio?

Also does anyone use TSP in their mix for concrete?

Yes, we always pre-treat concrete unless it is a shopping center on a weekly basis or clean enough to not have to warrant the extra expense. Where you are located will dictate what you will pretreat the concrete with.

Always pretreat if you have dirty moldy concrete understand most of this concrete will be very neglected.Some customers wait 15 years an walk out one day and say wow my concrete needs cleaning.They call the local wash man an his job is to remove 15 years of yuck in 2hrs.Work smart an apply a very strong mix down an let it work a few more gallons of chemical cost will well be worth it when you make that first pass with the surface cleaner you will be a hero in the customers eyes.Good luck with your cleaning.

Thanks, It seems like my mix is never strong enough for the concrete. For small spots I use my pump sprayer which works great to break it up.

Pre treat with house wash or EBC then post treat with house wash. The cost to me is a none issue for a quality job.

On real dirty residential concrete, we pre treat. Go wash the house. Then come back and clean the concrete. Then post treat with a pump sprayer or electric sprayer depending on the size.

We do pre-treat sometimes on particularly bad driveways, patios, walkways etc. Usually if it's really grimy we'll DS our hw mix, wait ten minutes then clean. Makes surface cleaning a lot easier especially on mixed agg.

The pretreat with water idea is actually true. A lot of times it helps to just wet it and rinse the surface dirt and stuff real quick. If it's real bad worse case scenario (moldy mixed agg for instance) I'll pretreat with a strong roof mix via 12v. You'd be amazed how much that will clean in 5-10 mins dwell time.
