Architectural & Structural Adhesives were required to draw up a specification for the repair of tiling in the pool where the existing grout had been eroded away, and areas of the existing tiles had become loose and crummy. ASA product had not been used on the initial installation. ï The pool area was drained and allowed to dry. ï The loose and crummy tiles were then removed. The existing grout which was still sound, needed to be removed by high pressure water blasting. ï ASA specified that Superfixall be used to relay the small glass mosaic tiles on the walls, and the larger floor tiles in the channels of the rapids area. ï After 24 hours, once the adhesive had dried, ASA Megagrout LD was used for the grouting. The pressure jets used to create the "rapids effect" exert a lot of force which can erode away normal grouts. Therefore, a significantly resilient grout like Megagrout LD was needed here. ï The Megagrout LD has other benefits of being highly chemically resistant to withstand the demands of a public pool area. ï On draining the pool, another problem became evident. The reinforcing of the concrete had started to corrode where it had been laid too closely to the surface. ï These areas had to be cut out, the reinforcing sanded down and epoxy coated. The render was then modified with ASA Megalastic being applied over the area. The area was then retiled. ï The turn around for the pool needed to be fast and it was filled 7 days after completing the grouting. |
