Natural high grade lime filler and eco friendly non toxic lime fillers.

Auro 342 Natural High Grade Lime Filler is an eco friendly, non toxic lime filler which is ideal for use on traditional natural lime plasters. This high grade performance lime filler perfectly levels surfaces with uneven absorbency, such as gypsum plasterboard, prior to coating with high-grade lime paints or plasters. Made with eco-friendly mineral fillers, calcium hydroxide, and cellulose, this product is ideal for repairing minor defects, surface levelling, and even for use underneath lime paints and lime plaster inside.

It can be tinted with Auro 350 lime tinting base, or compressed with a smoothing trowel to produce glassy wall surfaces. A top quality natural and eco friendly high grade natural lime filler for interior walls, Auro 342 is versatile enough to bond with and replicate any rendered finish, all in a natural, organic formulation.

We offer 2 types of tester pots on most products on all pages (in the drop down box)
1) ‘Colour Tester 100ml – (Standard colour matched pot for all Graphenstone paints)’ £4.50 per tester pot. We use our premium grafclean paint to offer sample pots in all colours we offer. The colour of this tester is exactly the same as the colour in the other paint ranges, which is why we offer it as a standard tester pot (as it’s cheaper as we can use this one paint for all colours). We mix this per order.
​ 2) ‘Colour Tester 100ml – (In this specific paint to test texture or sheen)’ £7.20 per tester pot. For people who want to check the exact paint, we also offer a tester pot in the actual paint (for people who want to check texture / consistency) as the colour is exactly the same as the standard tester pot.

Large orders of big tubs will need to be sent on a pallet, so may be +1-2 working days.

ECO PACKAGING: Testers use bio degradable corn starch infill packing pieces (these are only suited to testers and very light weight items though); on larger products we either use recycled/recyclable brown paper or we’re just starting to use pulped cardboard inserts for 2.5l and 5l tins - these are recycled and can either be recycled with household cardboard, composted or several people use them as firefighters!

Add products to basket and click estimate shipping to see costs.

All weekend orders are processed on Monday morning. We always advise trying a tester pot first.

Please Note: All products (paints / finishes / oils / waxes etc) are held in white and clear only, everything else is hand coloured specifically to your order (when you select from a colour range) by our wonderful mixing team, so unfortunately cannot be returned. Please please please try a tester pot first beforehand!
