The owner of this house in the village of Silkstone near Barnsley had discovered this clay Pamment floor when they had a tiler come in to tile the floor. The tiler stripped off the Vinyl floor covering and removed an inch of Bitumen that it had been stuck onto. With the Bitumen removed it became clear that there was wonderful Pamment tiled floor already there. They had a go at restoring the floor themselves but eventually decided to call in the experts.
Having been buried under Bitumen for such a long time the floor had a number of serious issues that would need addressing during the restoration. The grout/cement between the tiles was crumbling and there was a thick layer of dirt ingrained in the clay, there was also evidence of inherent salt efflorescence issues which manifests as white staining.
Pamment tiles are very similar to Terracotta in that they are made from clay and like Terracotta are very porous and need to be sealed to protect dirt getting into the pores. You don’t normally see them in use in Yorkshire, but are quite a common in Norfolk and Suffolk where they are still made by Norfolk Pamments. Silkstone dates back to the Doomsday Book of 1086 and there are some very old houses in the village so you never know what your going to find.
Deep Cleaning a Pamment tiled floor
We removed what was left of the grout/cement from between the tiles using a special tool and replaced with a grout specifically made for wide joints.
The next day once the grout had fully cured we came back to do the deep clean starting by applying Tile Doctor Pro-Clean to the Pamments and letting it soak in for ten minutes. Then the tiles were scrubbed with a floor buffer fitted with a black scrubbing pad and running at slow speed.
The floor was then rinsed with water and the slurry extracted using a wet vacuum. With the floor clear we could see that the process removed had most of the grime but there were areas that needed a bit more attention. To tackle the stubborn stains and neutralise the effloresce salts that were in the tiles Tile Doctor Acid Gel was applied and scrubbed in.
After a final rinse to remove any trace of cleaning product the floor was left to dry out for a few days.
Sealing an Old Pamment Tiled Floor
Due to the age of these tiles, the inherent efflorescence issues and the lack of damp proof membrane we sealed the floor in a fully breathable sealer ‘Seal and Go Extra‘. This provides a beautiful satin finish and allows the floor to breath and any moisture to escape.
Our customer was delighted with the results and was so happy to restore another original feature of the house.
