Gronant Institute Wood Block Floor Sanding Restoration

In June 2012 we completed a quite large scale floor sanding project at the Gronant Institute, Flintshire, North Wales where we totally transformed and restored a large Pitch Pine Parquet Wood Block floor that was looking very much the worst for wear and was desperately in need of a complete restoration to the main Hall area in the building.

The material we were working on was original Pitch Pine Parquet Wood Blocks, which had not been restored for many decades, we were also contracted to renovate the stage area, the boards on the stage were wide pitch pine planks, not dissimilar to scaffolding boards in appearance, again the boards on the stage were in a quite poor state and would need a lot of work to bring them back into good condition.

As you can see from the pictures below, the main Hall area of the Institute [150m2] had a Badminton court marked out, this was to be re-marked in white after the sanding part of the operations were completed. The pitch pine parquet block floor was in a pretty poor condition overall and needed a large amount of sanding works to bring the surface back into the high quality condition in which we left it.

15 large bin bags full of wood dust bear testament to the amount of material we removed from the floor, but as the blocks were nearly 30mm in thickness, taking 2 mm off overall doesn't make too much difference, We had to make two passes over the whole area with 24 grit floor sanding belts to remove the worst of the surface, which was pock-marked with thousands of high heel marks, we then worked our way up through the sanding grits to leave the surface beautifully smooth in readiness for the lacquer system we were to apply to the floor.

For the first coat on this parquet floor we used Junckers Baseprime to give a lovely warm and natural colourization to the timber and also to protect the subsequent coats of lacquer from any possible cross contamination. The high quality lacquer system we used for this project was 1 x coat of Junckers Baseprime followed by 3 x coats of Junckers HP Sport, [HP stands for High Performance] this 2 part lacquer is most definitely top of the range.

As mentioned earlier in the article, a Badminton court was to be re-marked back onto the surface of the hall, for this we had our friends at Renovate Contracts come in and undertake the line marking works for us, as the pictures show, the badminton court looked superb with the crisp white lines set against the restored golden honey coloured pitch pine parquet, our clients were absolutely delighted with the finished Main Hall floor.

After the works on the main Hall floor were completed we then moved onto the Stage area, which was 40m2 in size, Wide board pitch pine floorboards in material which was in a pretty poor condition. This area needed a lot of work, but thankfully sanded off reasonably well and looked stunning when fully completed.
