Step-by-step from prep to top coat. Filmed on the tools, not in a studio.

We supply premium waterproofing products backed by expert advice, fast service and real-world experience.
3m x 3mm aluminium angles are used as screed rails for cementitious topping screeds, as straight edges for spreading levelling compounds, and as guides for cutting sheet membranes to length.
Yes. After use, clean off any cementitious or polyurethane residue and store flat. Aluminium will not rust, so they last for many projects with proper care.
Place the angles at the desired screed thickness using mortar dabs or shims, level them with a spirit level along their length, then screed between them with a straight edge. Remove and patch the rail line after the screed has set.
3mm aluminium is the standard thickness used by professional waterproofing applicators - rigid enough to hold a straight line under typical screed pressure but light enough to handle on site.
Yes. Aluminium is corrosion resistant and suitable for both internal and external use without protective coating.
