K Lime Bond Coats
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.
