Hello all,
I'm by no means a concrete expert, neither I believe is anyone in my area. I used a local lumber yard to build an economical 36x24x12 garage and specified a polished 6" deep concrete floor.
The contractors overall did a nice job for the total price. Of course there are small bits that I'm not totally satisfied with, but in perspective this is garage and not a centerpiece of existence.
They poured a foundation with rebar securing concrete block. The blocks were rebarred together and also filled with concrete. There was a vapor barrier put down and 6" of 3500 psi concrete poured with fiberglass added. Expansion / control joints were put in basically in 9' squares (sort of like metal rail thingys).
The floor was then sanded (polished / smoothed). The exposed fiberglass threads were burnt off and the floor sealed (?) coated three times - drying each time in between - with oil based concrete sealer, clear gloss (see photo).
Overall, like I said I'm fairly pleased, but it appears that they really didn't get the floor super clean between the coats of sealer. There is blown sand / dirt that you can see and feel embedded in the floor.
I'm not sure if this sand / dirt embedded it going to cause me problems down the road and figured folks on this board would have some opinions / ideas / experiences.
I'm guessing the only real corrective action would be to re-sand the floor and re-seal. I'm not sure this would work and might make matters worse (opinions ? ).
FYI, the garage is in SC and rarely sees freezing temperatures, mostly just heat during the summer. There is no insulation / cooling planned at this time.
Any thoughts would be appreciated.
Thanks!
