Just moved into new house and kids had a bath last night, they always manage to splash plenty of water onto floor (carpet) the water then appeared through the living room ceiling (argh) on inspection, I lifted carpet and found existing wood (board) flooring (not laminate) had gaps at the biggest points some 1/4 - 1/2" wide.
What can I use to fill these gaps in with(drying time and movement to take into consideration) until a new bathroom & floor is saved for.
Thanks all.
