No Nonsense Decorators Caulk (Price: £2.03 )

No Nonsense Decorators Caulk is the perfect product for sealing those small cracks in the internal structure of a house. Cracks in plaster, cracks along skirting boards, peeling wallpaper, nail or screw holes in walls can all be sealed very easily with this product. Simply squeeze a bead of the paste along the offending crack and then using your gloved finger or a spatula, spread the paste evenly along the crack. A little practice makes perfect. You can paint over the dried paste. Follow the instructions on the container. You will need a caulk-gun (£6.39) to squeeze the paste from the tube.
