Concrete Blasting

Why use Sandblasting with Concrete?

Are you one of the people in Jax FL that asks, “How to repaint off concrete, driveways or sidewalks?” To begin, sandblasting is the process of shaping, cleaning and smoothing surface, especially the most difficult ones, by blasting solid particles across the surface at high speeds.

Concrete, cement, bricks, blocks and stone are a porous substance. When they are painted, some of the paint actually soaks into the surface and below the surface. So if you scrape or sand the surface, you’re not able to repaint that is in the pores below the surface. So some of the paint always shows through. Therefore those techniques are not effective at painting services or stain from concrete, cement, bricks, blocks and stone.

However Sandblasting can actually reach into those pores and clean them out. This technique is 98% effective (and the most bang for the buck) and does not change the natural look of the substrate.

For 100% effectiveness, in a worst case scenario, sandblasting will effectively repaint completely as it is capable of removing the porous layer along with the paint so there is zero paint showing when it’s complete. This will remove a very small layer of concrete, cement, block or stone. Its fine for those and their natural appearance does not change. But that last 2% improvement is certainly in the category of diminishing returns. That last 2% improvement raises the costs 25%. OUCH. Now we’re are not just repaint, now we are removing stone with it.

Sidewalks and Driveways.

Surfaces you walk on. As many homeowners have discovered to their dismay, painted walkways and drives become very slippery when they are painted and rained on. When it’s wet, it’s like walking on ice. This becomes highly dangerous for some people.

The Enclave hotel and suites in Orlando Florida had this problem.

In hopes to improve the appearance of the property, they painted a half mile of sidewalk. It looked beautiful color coordinated and all. The next time it rained on the newly painted sidewalk, 5 of their guests slipped and fell. They realized this had to be repaired right away. ½ mile is a lot of sidewalk.

They got estimates for sandblasting and repaint. I came in and gave them a free test blast so they could see what to expect. They loved the result but thought basting sidewalks was too expensive as it didn’t cost nearly that much to paint it.

They contacted their paint distributor, who by the ways wants to sell lots of paint, and he recommended they repaint it with a special no slip paint and told them it would solve their problem.

It was a lot less expensive than blasting so Enclave went that route and painted ½ mile of sidewalk a 2nd time. Next time it rained, more guests slipped and fell. Ut oh! They called me up and gave me approval for blasting the sidewalk. But now it had 2 coats of paint on it and not 1. Not knowing what that 2nd coat was like, I went back and did another test blast.

Ut oh! While this 2nd coat of non-slip paint did not remove the slipperiness when wet problem, it turned out to be amazingly durable and stubbornly slow to remove. I refused to honor my 1st quote for removing 1 coat of paint now that it had 2 coats and the new coat was super stubborn. I was forced to double my 1st price quoted.

Well I’m sure you can imagine their reaction, but since I was the lowest bidder, they did hire me although they never were friendly to me. I believe I got blamed for their stupidity. Hhhmmm is all I can say. (Actually that is my really polite opinion)

Another reason to sandblast painted concrete?

If it’s a wall and it’s been painted before, but it’s now aging and peeling, adding another layer of paint atop of a peeling layer is a sure way to throw your money away as the peeling layer will continue to lift up and remove your new layer. So if it is peeling you must fully remove that old layer so the new paint can completely bond with the substrate. Then the new paint can last for another 15 years.

There you have it. The most common, but not complete list, of reasons for sandblasting concrete, stone, block & brick.
