Drilling and Foam Visual Demo
Here is a quick drilling and foam demo which is the first step to repairing a fiberglass bathtub or shower. Notice how I find the shallow and deep layer support. Most times (but not always) you will find tubs and showers will have 2 gaps. One between the floor and the support board (shallow layer) and one between the support board and the subfloor (deep layer). Be sure to check for both and fill both using our floor support foam.
