SX302 TREMSmooth MT

Product Spotlight: SX302 TREMSmooth MT – Fast, Moisture-Tolerant Flooring Solution

When working on fast-paced flooring projects, contractors face a familiar set of challenges: moisture issues in the substrate, strict deadlines, sensitive installation environments, and the need for a finish that can be achieved quickly and reliably.

That’s where SX302 TREMSmooth MT comes in. Part of the newly re-engineered TREMSmooth range, SX302 has been reformulated with contractors’ feedback at its core. The result? A moisture-tolerant, fast-turnaround smoothing compound that gives contractors confidence when working in tough environments.

Moisture-Tolerant Smoothing Compound

Moisture in subfloors is one of the most common causes of project delays. SX302 directly tackles this problem with its moisture-tolerant formulation, making it suitable for use below surface damp-proof membranes. Contractors can move forward with installation instead of waiting on extended drying times or complicated prep work. And, for environments where cleanliness and hygiene matter such as hospitals or food preparation zones, SX302’s protein-free formulation ensures it can be safely used without risk of biological contamination.

Faster Foot Traffic, Faster Programmes:

Deadlines are always tightening, and contractors need products that help them deliver projects at speed without compromising quality. SX302 supports fast-track schedules thanks to:

Accept Foot traffic after approximately 90 minutes.
Easy mixing and application
Reliable consistency for achieving a smooth finish with minimal effort.

The ease of use keeps labour time down, while the rapid walk-on time keeps trades moving, a major win for busy sites. Contractors know the discomfort and disruption caused by high-odour products. SX302 is formulated to be extremely low odour, with no unpleasant ammonia smell, making it ideal for occupied buildings or sensitive refurbishment projects where indoor air quality must be maintained.

Where SX302 Performs Best:

SX302 is built for environments where durability, moisture tolerance, and speed are non-negotiable. This includes:

Healthcare settings
Food production areas
Fast-track commercial refurbishments.
Moisture-affected substrates that require reliable preparation before flooring installation.

It’s a versatile solution that fits into real working conditions that contractors face daily.

By combining moisture resistance, fast walk-on times, easy handling, and a low-odour formula, SX302 helps contractors reduce downtime, avoid costly delays, and maintain consistent, high-quality finishes.

Jonathan Roberts from Tremco's R&D team shared, "We’ve refined our formulas based on customer feedback to enhance application properties. By improving working time and flow, we’re giving contractors the ability to achieve higher quality finishes more efficiently.”
