FAQs

Where is the Large (2 1/2" – 4 7/8") platform typically used?

This platform is built for thick-bed mortar applications — common in commercial floors, ramps, step-downs, rebated concrete slabs, patios, rooftop decks, pool surrounds, and landscaping projects.

It’s ideal for perimeter areas or any zone that requires extra height and a consistent, code-compliant slope-to-drain.

Can I use Screedex® with reinforcement wire or mesh in my mortar bed?

Yes — and it’s especially recommended for thick-bed mortar screeds. Pair your Screedex® platforms with the Screedex® Reinforcement Support to keep wire mesh properly suspended above the subfloor. This improves structural strength and helps prevent sagging — especially in commercial or high-traffic areas.

Can I combine the Large platform with other Screedex® sizes?

Absolutely. Use the Large at high points or perimeters, Medium for mid-range areas, and Small near drains or low spots. Mixing platform sizes helps you build a smooth, code-compliant slope-to-drain across the full floor area.

How do I know if the Large platform fits my project?

Measure your mortar bed depth in multiple spots. If any area falls between 2 1/2" and 4 7/8", the Large platform fits. Combine with other sizes to cover the full depth range of your floor.
