Independent Tests at the PRA Coating Technology Centre are said to have shown that Polycell Trade Interior and Exterior Polyfilla have outperformed their rivals when it comes to good preparation.
The centre blind tested a range of fillers on criteria including consistency and ease of application, even-ness of set and smoothness, finish after painting and adhesion.
The scores across each criteria were totalled and the duo came out on top, next to comparative products.
