Concrete Sealant Calculator
How much concrete sealant do I need?
G4 Concrete sealant comes in Clear, Black, Blue and Green finish and can be used to seal concrete ponds, or coat flagstones, waterfalls and other concrete structures.
Enter the dimensions that represent the longest, widest and deepest dimensions of your pond. This means that you won't run out of concrete sealant before you've finished the job.
