Block-Filling Walls for an Efflorescence Removal Project

Friday, February 08, 2019

In our January 25th blog post, we talked about a dry-ice blasting project for efflorescence removal. As we noted then, we finished the first phase of the project in just four days, blasting all of the walls of the 6,800-square foot industrial facility in Racine, Wisconsin.

The following week (January 24th - 28th), our crew finished block-filling the walls that we had dry ice-blasted. All told, we applied 40 gallons of block filler primer to the three walls. This required our crew to apply one full even coat of block filler primer. We did this by spraying and backrolling. 

There were a number of challenges during the block-filling phase. Between the sub-zero temperatures and the snow advisory here in Wisconsin, it was a bit of a struggle for the crew to make it to the jobsite, to the say the least. The ice-covered roads create a safety hazard while driving, while the temperatures made it dangerous for our crews to be outside for extended periods of time. On top of these issues, vehicles really don't run well if at all in such frigid, icy conditions. That said, we were able to finish the block filling in as timely and safely a fashion as humanely possible. 

Beyond the safety challenges, our crew had some difficulty accesing two areas, both located above the bathroom build-outs on either side. The area could not be reached with the standard scissor lift we have on-site, so we had to turn to an articulated boom to finish the work. 

In the slideshow above, you can see the progress we made in the second week of work with the application of the block-filling primer. To emphasize the progress, we've included some photos of the walls full of efflorescence, as well as our crew dry-ice blasting to get to a clean surface for priming (this can be seen in the four images that follow the first two photos of the slideshow). As expected, the facility is really starting to look much improved given the extensive efflorescence we first encountered throughout the space. 

In a future blog post, we will showcase the finish coat and the completion of masonry block, as well as the painting of supply piping that is color-coded for corresponding internal material (safety yellow, red, and green).
