950 square metres of screed was laid at retail outlets in the O2 shopping centre. The products used were Ronafix Mix A and RonaScreed FastDry Prompt. Ronafix Mix A was required for thin bonded levelling screeds and RonaScreed FastDry Prompt was used to shorten the drying time of thicker screeds, to reduce waiting time before floor finishes could be laid and allowing the early return of site traffic.
Wates Construction was contracted to refit a former Wetherspoons pub at the O2 shopping centre in north London, turning the space into three separate retail outlets. Part of this project involved the levelling of the floor.
Product and application
Screeding contractor JF Flooring was sub-contracted to carry out screeding works and so contacted the Ronacrete Technical Team to discuss suitable screeding products to meet the job’s requirements.
Two Ronacrete products were recommended for the project, Ronafix Mix A which could be applied in thin section and RonaScreed FastDry Prompt which was added to the screed mix where thicker screeds were required. The thickness of some areas of screed was in excess of 100 mm and there was not sufficient available time for drying of traditional screeds. The addition of RonaScreed FastDry Prompt additive to the mix ensured fast return to use by site traffic and early drying, ready for the application of floor finishes so that shops could be opened without delay.
“We found the product easy to use and it provided a first-class finish, meeting all the required specifications and in accordance with British Standards. The main contractor was also happy with the finish and overall appearance of the screed.”
The Ronacrete screeds provided level surfaces within the three shops. Early drying times meant the screeds were soon ready for the application of floor coverings, avoiding delayed completion of the project and ensuring that business could start as soon as possible.
Aggregate is usually 0–4 mm and is mixed with cement in the ratio of 1:3 or 1:4 cement to sand, depending on strength requirements and drying requirements. For total screed thicknesses in excess of 50 ...Read more
