Poultices

PureSeal Poultices – Targeted, Professional Cleaning for Masonry and Stone

At PureSeal, we specialise in cleaning and protection systems that restore and preserve the natural beauty of stone, brick, concrete and other porous materials. Our poultice range has been designed to tackle the most stubborn, deep-seated stains safely and effectively — whether on modern buildings, heritage properties, or sensitive decorative surfaces.

Poultices work by drawing contaminants out of the substrate, rather than pushing them deeper in. This makes them ideal for use on stone and masonry, where maintaining surface integrity is just as important as achieving a clean finish.

How Poultices Work

A poultice is a thick paste applied directly to the contaminated area. It combines:

An active cleaning agent, formulated for a specific stain type.

An absorbent medium, which pulls dissolved contaminants into itself as it dries.

Once the poultice has cured, it is carefully removed, taking the stain with it. Because the paste stays in place during treatment, it offers precise, controlled cleaning — reducing runoff and minimising risk to adjacent materials.
