K Lime Bond Coats

Our K Lime Bond Coats provide a preparatory coat for substrates with poor suction.

K Lime SB1 (Stipple Bond 1)

K Lime SB1 is a Stipple Bond. It is a cement-free preparatory coat to combat problems due to insufficient key or poor suction. It is used to give a larger surface area and improve the adhesion of K Lime renders to difficult substrates such as natural stone & brickwork.

It is applied using a hawk & trowel, scrubbed into the surface and immediately textured to leave a rough stipple finish.
