Apply it to fit and seep on the gap between the surrounding boards and laminate floor. Continue applying the area with gaps, if need be press the flow with a wet finger to make sure it runs along the caulk line.

You may wipe the excess caulk on your finger with a wet rag. Press it just hard enough to smoothen it into the line. Remove the masking tape along the area caulked. Let the caulk dry for up to 24 hours before using the floor or painting the floor.
