Introducing a new decorative screed that is rapid-setting and suitable for fast-track installation.

A newly developed, industrial grade, rapid-setting and self-smoothing decorative screed called X-Tech StoneFlow has been introduced by TAL X-Calibur.

Polished, decorative and seamless concrete floor solutions are in high demand, however terrazzo floors can take up to 28 days to cure before grinding and polishing can commence. For this reason, TAL X-Calibur joined forces with Rock Solid Flooring and HTC polishers to develop and introduce a new flooring system throughout South Africa. HTC polishers are marketed through Superb Flooring Systems, which is part of the PMSA Group.

“We’ve identified a need in the market for a rapid-setting decorative screed, suitable for fast-track installation, which can create a polished and seamless concrete look without the long curing time associated with terrazzo floors,” says Andrew Dekker, National Sales Manager Construction Products at TAL.

X-Tech StoneFlow is a cement-based, rapid-setting, self-smoothing, shrinkage-compensated and heavy-duty decorative industrial screeding compound available in varying combinations of base colours and aggregate finishes.

It enables specifiers and designers to create a custom floor as they can select the specific background colour they prefer along with several aggregates, including marble and granite chips.

The screed is designed for use in industrial environments on both new construction and renovation projects. It is suitable for applications exposed to heavy traffic and abrasion, such as factories, warehouses and production areas. It’s also seamless and therefore low in noise. Due to its decorative qualities, X-Tech StoneFlow is suitable for commercial applications such as the hospitality industry (it works well in restaurants), as well as domestic applications.

Tests conducted by the South African Bureau of Standards (SABS) show that X-Tech StoneFlow has a compressive strength in excess of 30MPa at 24 hours. SABS is conducting a wide range of performance tests on the product to give customers confidence that they are getting a state-of-the-art product.

The surface can be subjected to light foot traffic after three hours. Grinding and the first stages of polishing can commence within five hours of placement, depending on application thickness and ambient conditions.

Application of X-Tech StoneFlow requires fully trained specialist contractors as it involves grinding and polishing. The final finish is only achieved by using specialised equipment (such as the HTC super floor polisher range) designed to polish concrete terrazzo and similar types of floors.

The HTC Sealer is applied before final stage polishing to prevent moisture penetration and staining. The floor also requires maintenance polishing to uphold its high-gloss shine. No chemicals are required during the maintenance polishing process.

TAL’s products are manufactured locally, are compatible with South Africa’s climate conditions and are in line with the latest technology. X-Calibur Construction Chemistry forms part of the TAL building solutions range and consists of construction product solutions with an emphasis on flooring and surface treatments, concrete repair and protection as well as anchor groutings and fixings, sealers and coatings, floor hardening compounds and waterproofing systems.
