Coarse Stuff Lime can be used for pointing stone and plaster undercoats, so is suitable for a wide range of projects including historic building renovations, and conservation work. Unlike hard cement mortars, they have a natural elasticity, which allows them to absorb minor building movements. They are also a ‘breathable' mortar, meaning that moisture does not stay trapped in walls, creating a healthier and more natural living environment.
Our coarse stuff is carefully made from mature lime putty and selected aggregates, packaged in tubs or bulk bags it can be conveniently used in small amounts as required.

Coarse Stuff is a traditional lime putty-based undercoat plaster for masonry and lath, made from mature lime putty and selected aggregates. Unlike hard cement-based undercoat plasters, they are 100% breathable meaning that moisture does not stay trapped in walls, creating a healthy and more natural living environment. Coarse stuff also has a natural elasticity, which allows them to absorb minor building movements.
Inside the tub you will find a premixed non-hydraulic lime undercoat plaster, ready to use. Non-hydraulic lime products set by carbonation which is a gradual process which gives the product a long shelf life, providing the tub is kept sealed and airtight. The mix may stiffen over time in storage but can be ‘knocked up’ again and again to the ideal consistency.

Ensure the background is thoroughly clean. If the background is saturated, then check externally for cracks or other causes of water penetration. Causes of damp should be remedied first eg re pointing outside with a hydraulic lime mortar. Joints should be racked back normally 10mm to provide a key for the undercoat. Apply sufficient water to reduce excessive suction, especially on bricks and porous stone. This may have to be done more than once before application.Always dampen down before applying subsequent coats.
When dubbing out on defaced surfaces it might be necessary to apply a dubbing out coat which should be applied 3-4 days before application of the undercoat.
Undercoat / Scratch Coat:
Normally 10-12mm and if required thicker then apply in two coats, leaving 3-4days between applications. Where different materials meet and where there are timber lintels, it’s advisable to apply laths first.
A float coat is to be applied 4-5 days after scratch coat. Check for shrinkage during first 2 days and, if necessary, lightly dampen, scour back and re key. Please wait 4-5 days before application of a finishing coat. When plastering on laths wood lath backgrounds should be well wetted the day before and again 2 hours before application. Always use haired coarse stuff except for finishing coat. Apply diagonally across the laths.
