A couple of years ago, I used decorators caulk to fill gaps between floorboards before painting the floor with V33 floor white paint. However, with normal use, the caulk's 'soft' texture attracts dirt, leaving an unattractive look between the boards. The dirt can be removed using wipes specifically on the area, but not using normal floor mop.
I've searched but have not come across others with the same problem.
Is this normal? Is it a problem with the particular floor paint or decorators' caulk?
Many thanks.
