[Shop-talk] Concrete floors and oil stains

[old dirtbeard]

Hi Tom,

I tried most everything, and nothing really worked for oil that had
penetrated the concrete.

Kitty litter ground into the stain with the end of a red brick worked the
best, but I eventually just gave up trying and went to vinyl flooring:

I used the diamond pattern gray for where the cars park and white
elsewhere. I should have used gray also for where the motorcycles sit as
they leave tire marks on the white when the tires are hot.

They are self-adhesive in 24" x 24" square tiles. They go down very quickly
once you have cleaned and sealed the floor reasonably well (stains do not
matter). I used this sealer/primer first:

Even if you are not going to lay vinyl flooring down, I would use this
sealer on the concrete as it prevents future oil stains, makes it much less
dusty, easier to clean, etc.

Aside from looking terrific, vinyl is much easier on the knees than
concrete, and it quiets down the noise as well. Things do not break as
easily when dropped. I used a good deal of white, and it definitely
brightened up the shop.

They will mark-up and can be gouged with sharp jack stands, etc, but a
ruined tile is very easy to replace if you wanted to.

best,

doug
