Hello, I had to break up to sew a spout in the shower wall and I have to fill a wall hole 30 cm long x 5 cm wide, to then put ceramic tiles, I necessarily have to make a thick mortar mortar (buy bag of cement and lime, which is going to spare me all the bags) to seal the hole or can I buy another type of product and be able to save the cost?

Hi. If you go for any work you will be given the materials to make 1/4 or less of a bucket to cover. Otherwise in the hardware stores you can buy the cement for Kg and the sand can be removed even from the side of the river. regards
