About the Bonda G4 Clear Pond Sealer - 25kg
Manufacturer: Bonda
The perfect solution to sealing concrete ponds.
Concrete-based ponds need the final render sealing to stop the water getting in and lime leaking out. G4 has been long established as the market leader for this task. The amount of G4 you will need depends on the internal dimensions of your pond. For example lets say the pond is 3m x 2m and 1m deep. 1) Work out the area of the bottom (in our example 3 x 2m = 6sqm). 2) Find the area of one of the sides. then multiply by 2 to cover both sides (in example sides 1 = 2 x 1 = 2sqm x 2 = 4sqm). 3) Find the area of the other pair of sides: (in example sides 2 = 3 x 1 = 3sqm x 2 = 6sqm). 4) Add up sides and floor (6sqm + 4sqm + 6sqm = 16sqm). 5) Multiply total by 550gsm = 16 x 0.55kg = 8.8kg.
