Validus Structa Standard Set S1 White Tile Adhesive — Pallet of 48 x 20kg Bags

Validus Structa is a premium fibre reinforced, highly flexible thixotropic tile adhesive engineered for professional tiling across a wide range of substrates and environments. Formulated with high strength cements, graded aggregates and special synthetic resins, Structa delivers outstanding bond strength, extended workability and genuine S1 flexibility — making it a reliable choice for demanding interior and exterior installations.

With a 30-minute open time, 3-hour pot life and the ability to grout and accept light foot traffic after just 12 hours, Structa fits comfortably into trade working schedules without compromising performance. It achieves bed depths of up to 15mm, handles large format porcelain slabs with ease and is fully compatible with underfloor heating systems.

Why Choose Validus Structa?

Structa is designed for tilers who need a dependable, professional-grade adhesive that performs across a broad substrate range — from concrete and screed to tile backer board, plasterboard and even timber floors subject to slight movement. Its thixotropic nature ensures it stays put on vertical surfaces without slumping, while the extended open time gives you the workability to handle large format tiles accurately.

This white variant is the preferred choice when working with light-coloured tiles or natural stone where adhesive show-through must be avoided.

Suitable Substrates

Walls and floors, interior and exterior. Concrete and cement-based screeds, tile backer boards, heavy duty and trafficked areas, swimming pools, terraces and balconies, flexible waterproofing membranes. With appropriate primer: wooden substrates, gypsum boards, plasterboard and anhydrite screeds.

A primer is recommended on absorbent surfaces. Do not use on plastic or metal substrates or substrates subject to rising damp.
