Anyone who has even worked with concrete knows that dealing with the elements can sometimes pose problems. When the San Juan Museum of Art had the concrete slab poured for their new atrium, there were many factors that weren’t ideal.  What they got was certainly not what they were hoping for.  The uneven color and small surface cracks over the re-bar in the slab were unsightly and would only serve to detract from the art they wished to display.  We were contacted to resurface the space and resolve the issues getting it back to concrete canvas they originally wanted.

Since they were already behind in the schedule, tearing out the slab and re-pouring it wasn’t in the cards. Resurfacing with a micro-topping, not only allowed the work to be done in less time, it cost less than starting over as well. It was a win / win for the Museum and the contractor who would have been on the hook for the repairs.

We started by grinding the entire surface to even it out. The larger cracks were chased and then filled with a flexible joint filler. We then installed a medium aggregate integrally colored micro-topping base coat. This was sanded and then a fine aggregate coat was installed with the same integral color. Once this has dried we sanded the floor and applied a water based epoxy primer to seal it. Since there were several decorative saw cuts that were now full of micro-topping, we re-cut everything to open them up again. Once everything was cleaned and vacuumed we applied a high performance gloss urethane.

In a few days, the cracked and discolored slab was looking better than new and after a few final projects the Atrium was ready to display art. For information on the museum you can visit their website here:
