Expansion gap details
1 of 1
Hold off on setting the toilet and the baseboard molding until you've filled the expansion gaps around room perimeters and the toilet flange with 100 percent silicone caulk.
Anytime you install laminate flooring
in a bath, laundry room or
kitchen, you should use AC3-rated flooring, leave 1/4-in. expansion gaps at the walls and fixtures, and then fill the gaps at flooring
ends with 100 percent silicone
caulk. It stays flexible, allowing the
floor to expand, and in the event of a
spill, prevents water from soaking
into the laminate core. Filling the
gaps can use up a lot of caulk, so buy
more than you think you'll need.
