Poultice and chemical cleaning techniques are essential when traditional abrasive or water-based methods are unsuitable. These systems are particularly valuable for treating sensitive historical surfaces, such as listed stonework, carved masonry, and fragile substrates found in heritage sites and places of worship where dust or moisture must be avoided.
These specialist cleaning methods are also ideal for addressing deeply embedded stains and persistent coatings that cannot be removed effectively through blasting or superheated water alone. Poultices and targeted chemicals can safely break down and draw out contaminants without damaging the underlying surface by allowing for extended contact time.
A poultice is a specially formulated thick paste that contains active chemical agents. It is carefully trowelled onto the affected area and then covered to maintain moisture and enhance effectiveness. The enclosed treatment penetrates the surface and emulsifies paint, oils, soot, or other staining agents. After 24 to 48 hours, the paste is peeled or scraped away, lifting the contaminants.
Conservation architects and planning authorities often recommend this noninvasive method due to its gentle but highly effective results.
At Blast Clean Scotland, our operatives are trained in safely and effectively applying poultice and chemical cleaning systems. We carefully assess the substrate and condition of the surface before recommending the most suitable method, ensuring that cleaning is carried out without harm or disruption.
