Length of joint [m] = 310 ml / (Joint width [mm] x Joint depth [mm])
Liters / Meter run of joint = (joint width [mm] x joint depth [mm]) / 1000 [m x mm² / l]

Triangular joints (where the sides of the joint meet at a right angle) shall have sides ≥7 mm.

The joints must be clean and free from dust, grease and rust. On porous surfaces such as concrete, stone, cement and plaster a primer (mixture of one part acrylic sealant and 4-5 parts of water) can be applied.
