These weekly videos are generally good - this one is outstanding! Jason's right: if you are a decorative concrete contractor looking to downsize, but you don't have the heart to fire anybody, you can just sell a bunch of strip-and-reseal jobs and your people will just quick because THAT WORK SUCKS! Just to add to this, I have a solution if you find yourself with an interior floor with acrylic to strip (first of all, shame on anyone installing acrylic indoors: interior floors ought to be diamond polished so they are serviceable). Anyway, in major cities there are companies with truck-mounted deep cleaning systems that use super-heated water that will strip acrylics. Cintas is an evil empire that you should never get uniforms from (5-year deals nobody can escape where they will sneakily ratchet up the cost 100s of %), but they have a "deep-clean" division that is incredible. It's not as good as sandblasting because it drives a bunch of water into the concrete, but indoors it is hard to beat (fully contained and re-claimed).

After sand blasting, do you have to antique and seal the same day, or can it wait a day or two? Also, if it rains after sandblasting, how long should you wait for the patio to dry before antique and sealer?

[JamesONLINEREPRESENTATIV-nqwp]

Please my question is how do you re antique before sealing. Please can I get a better explanation on how to apply the liquid antique the is taking from the bucket. Is it mixed with water or something else?

[GetToThePointplz]

Very professional, would hire you to do mine

Hello. I live in Sydney Australia. Do you deliver to Australia ? Is there already a similar product already in Australia that you know off that i could source ?
I have recently seen a stamp job that turned white in areas. I will have it soda blasted tgen re sealed, but discovered the re antiquing while researching your videos. Very interesting and thorough explanation, well done. Niko

[Ritzi]

That doesn’t take the release off also ?

THanks for the video, but--easy to say all this about stripping and drain-off or sandblasting on an outdoor surface. What if someone needs to do this on an interior residential floor?

[cantoncardcollector]

Looks beautiful! How often should stamped concrete be resealed?

[fastvic]

hi great video how much is it to sand blast it thank you i can get a firm to do it in uk said it will break the concrete up so i show them your video

[jeff_]

There are some areas on mine that were dusted to get some black outlining when stamped to show the texture. Is that called antiquing? Will that get blasted away when sand blasting? Thanks!

[markhardin]

Hi, just wondering if you used a color hardener if sandblasting it would take the color off? Thanks for the great videos!

[ronaldvindivich]

Well you local franchise in Richmond should review this video. We had them redo a stamped patio and porch last year and they now look worse than before the project. Clearly over applied sealer on the porch, before sufficiently dry as it is now turning white. The Patio application is "peeling off"....just terrible to look at.

[DianeLindau]

I just had a company do a new patio and the antiquing job is horrible! They used a paint roller not a brush to apply the release and it shows pooling, spill spots and way too much product. The concrete owner went ahead and sealed it without my approval knowing the owner and myself had great concerns. Is sand blasting the only way to get back to the original, proverbial 'clean slate' or if he uses muriatic acid to remove sealer he could then address correcting the release issues - any help would be much appreicated! I can send pics if that would help.

[zachhaines]

Does this work for water-based sealers as well?

[nandygarcia]

How much does this patio cost to reseal

[kreteman]

Have you tried soda blasting yet? Heard it works well.

[grandcanyonpowerwashing]

Can you explain more about antiquing. We are on a project and it looks exactly like this. We are having a tough time with it.

[robbutler]

Ok, so sandblasting, re-antiquing, and re-sealing a patio that size. What’s that cost? 3k?
