Cleaning concrete what to use and what not to

I recently saw a new driveway that was cleaned improperly and caused a horrible stain.  Luckily this problem can me remedied, but it would have been best to prevent the problem all together.  So what do you clean your concrete surface with?

If you have a driveway or patio it would be best to use a product like mean grean or tri sodium phosphate.  These products are basically high powered soaps. The mean grean would work great if you have some oil spots.  One of the best cleaners i’ve ever seen and can be used form more than concrete is Orange TKO .  Once you use this product you’ll be cleaning everything including dishes and laundry with it. Before the product dries use a power washer and clean your surface.  This should work great.  Since you’ve gone through all of the work to get it sealed I would reccommend a water based siloxane sealer.  I would reccommend having this sealed by a professional because once you put a sealer down the time to ask questions and try and figure out the whats and whys has passed and you have a nice mess.

DON”T use muratic acid to clean your concrete….Please.  You would only use acid to clean if you were prepping it for paint and want to etch the concrete.   If you are scrubbing the concrete don’t use a wire brush it will burn the concrete. In the Kansas City environment I strongly reccomment not painting concrete that is exposed to the elements.

A warranty on concrete sealer? What a joke!

Have you seen companies advertising they can seal your concrete and give you a great warranty… usually a 30 year or lifetime or something of that nature.  DON’T get SCAMMED!!! What a joke.  I always find it funny that these companies brag about this warranty, but don’t allow you to read it on their website.  If it was so great…why couldn’t everyone take a look at it.  I finally got my hands on one of these sealing warranties and basically what it tells you is that if you can prove that there is no longer sealer present they will go treat the effected area with more sealer.  WOW !  Thanks!  People need to understand that a sealing company is not going to warranty your surface from any defects because they didn’t install the concrete so they have no idea of the workmanship.

These companies usually use great products…usually a siloxane sealer, but their prices are really high (we are usually half of what their price is and put down the same product) and many people go with them just because of a piece of paper.

Fall is coming so just a little FYI

Epoxy garage floors

Many people are now updating their garage floor with an epoxy coating.  Epoxy is an excellent product, but the truley good epoxies should only be used by professionals.  Every time I walk into a Home Depot or Lowes store I cringe when I see the epoxy kits for garage floors for a few reasons.  These epoxies are at a do it yourself “strenght”.  Many people that have put these down experience flaking with in a couple of years.  Also a do it yourselfer doesn’t have access to a diamond floor grinder that would allow for proper prep of the concrete surface.  An finally most of these “kits” don’t come with a clear top coat for added protection.

So if your going to do it yourself remember prep, prep, prep.  If you can lick the floor it’s not clean enough.  Also have a dry surface that doesn’t have a moisture issue, and as a general rule put the epoxy down when the ambient outside temperature is risining (starting at 50 degrees)

If you want to have a professional do it expect to pay around $3.50 to $4.50 per square foot.
