I just finished installing Racedeck diamond plate in my garage. I had built the garage about 4 years ago and used a concrete stain that was recommended by the local hardware store. The installation instructions said to wait 6 weeks for new concrete to cure before applying the stain. I waited the 6 weeks and never parked a car in it so there was no
oil. I acid washed the concrete as they recommended and then applied the stain. It looked great at first but started to fail after only a few months. It failed in all areas including a bathroom. I think the main problem was that the floor was poored much thicker than normal which then took longer to cure. Unfortunately, I did not think of this before I applied the stain.
By the time I installed the racedeck the stain was a mess. I could scape it and vacuum it up and by the next day more paint was coming up. It was like a fine powder that got all over everything. I decided to go with the racedeck since I could lay it over the failed stain. I felt getting the old stain off would require me to move out the cars, cabinets etc. and would take several days to complete and then there would be the time that it would take to install and cure an epoxy before I could put the cars and cabinets back in the garage. The racedeck was easy to install. I installed it under my lift but cut it around all the cabinets. I even installed it into a bathroom. I only had one car that I left out of the garage at night while I installed it (this is a 4 car garage). I used a pattern of 4 foot squares of black and white. It looks great.
From now on I will put something under sharp edged jack stands. I used them to hold up the lift while I installed the racedeck under the legs and they cut into the material. It wasn't real bad but it did leave indentations. Another thing is that direct sunlight will cause the area in sun to expand which can cause it to lift up a bit. As soon as the sun is off it the tiles go back down. We've had 100 plus degree days and as long as the sun isn't shining directly on it there isn't any lifting. As far as
oil leaking from the cars it wipes right up.
