Description: We at Del Zotto Products of Florida have used many different kinds of Sponges for grouting our Concrete Pipe and Structures, most have been low quality sponges that tear, wear quickly, fall apart, lose their ability to hold water when used grouting pipe and structures. These Sponges work! They do not wear out nearly as quickly as 99% of the others do, they do not tear easily, they simply hold up and that means they save you money!! These are the only sponges we will use and believe us we’ve tried them all.
Stop spending $5 + on sponges try these and see what you think. Give ours a try we bet you will come back for more.
