Approximately one year after the installation was completed, homeowner Joe Filler phoned his “builder” to inform him of a random discoloration in his sheet vinyl. The same vinyl is installed in the laundry room, the garage entry hall, the bathroom, the kitchen dining, and kitchen prep areas. The builder was informed of the condition along with the retailer. The distributor was then contacted to set up an inspection.
Can you guestimate the cause of the discoloration?
You make the call!
OK. We all see the knot, but in this case the knot is only a victim. Look closer at photos 4 and 5. What do you see inside the knot and the other voids? A filler compound made primarily of silicon (photos 6 and 7 show the reverse side).
Who installed the underlayment? The builder.
Believe it or knot!
