Etching concrete with a gel acid is the most effective solution. And it works!
If you have concrete sidewalks that have worn down and become slippery, this the remedy to prevent slip and fall accidents. The causes of slippery sidewalks are due to two main reasons:
- Foot Traffic will wear down concrete over time.
- Algae buildup from wet sidewalks that never dry.
For years the solution has been liquid acid which will create a profile on cementitious surfaces. The problem is handling the hazardous material and the lack of control. The results are ineffective. Sand blasting is another solution that works but with obstacles . Price is the first. A few years ago Sandblasting was as high as $1.50 per square foot. It is down to about 80 cents psf but still way above the price of using a gelled acid which is under 20 cents psf.
Additionally sand blasting requires expensive machinery and 3 people to operate. Plus cleanup is a mess.
Concrete etching with a gel acid is simple, effective and LEED qualified. And it’s also used in a system called Flattoos, which has created a cottage industry with graphic design on concrete floors. Vist www.etchingconcrete.com for more information.
