Ironstone Fine Finish Putty Plaster

A superfine rich lime putty topcoat manufactured with fine silica sand and extra fine mature lime putty, commonly known as Fine Stuff.

Ironstone ready-mixed Fine Finish putty plaster is a ready to use non-hydraulic lime plaster finish coat.  This super fine finishing plaster has been developed in partnership with Heidelberg Materials Socli as an ideal putty topcoat for application over Ironstone NHL basecoat plaster and Cornerstone Insulating plaster, as well as lime putty basecoat plasters.

The Ironstone Fine Finish putty plaster delivers a smooth professional finish on internal walls and ceilings and is suitable for contractors and DIY customers, offering reliability, durability, natural elasticity and excellent breathability.

Ironstone Fine Finish plaster is a wet ready mixed plaster manufactured in pan mixers on site in Yorkshire.  As a fatty lime with a high free lime content, our super fine putty finishing plaster offers even more breathability than our Natural Hydraulic Lime ranges and is ideal for restoring any old building.

With a natural anti-bacterial effect to combat mildew and mould
A fatty and workable plaster for those behind the trowel
Fine, smooth finish delivering professional-grade results.

Surface Preparation: Lightly spray the base coat and pour away any excess water in the tub before application.  

Application: Apply at 2-3mm in two passes. Avoid overworking, applying too thick or using too greater pressure on it as this can lead to crazing. See datasheet for the range of applications.

Curing: Do not use in temperatures below 5°C or above 30°C, or if freezing conditions are predicted within the following few weeks, including wind chill. We always advise following best practices for curing and protecting fresh lime renders and plasters. Protect from adverse environmental conditions, including frost, rain, direct sunlight and drying winds.

Storage: Non hydraulic lime mortars set by carbonation.  The characteristic gives the product a very long shelf life providing the tubs is kept sealed and air tight.  The plaster may stiffen over time but can be knocked up again and again to the ideal consistency. Store in covered and dry conditions

Coverage: A 10l/16kg tub is sufficient to plaster 4m2 at 2mm.

Painting - It is important that only vapour permeable paints are used to decorate it. Leave 4-6 weeks before painting. Only limewash may be applied immediately.
