Filling bug holes in concrete ornaments, statuary and pieces. In this video we mix cement at a ratio of 2 parts sand to 1 part cement, add a small amount of PVA glue/bonder and a small amount of washing up liquid/dish-soap to act as a plasticizer/plasticiser (plus water) to fill the bug holes which were present in the concrete pieces as a result of trapped air not being succesfully released and/or tapped/vibrated out during the pouring process.
