I just put baseboard trim down in my basement and there area few spots where there are small gaps especially where the two boards are butted up and in some spots along the top of the board where the wall meets the board. My question is what is the best way to fill these small gaps before repainting. Also in some spots there is no way to secure the board to the wall due to no stud, is liquid nail a good option in these spots or just caulk it. Thanx
