Frequently Asked Questions
What is the advantage of the 8-mat case over a 4-mat case?
The 8-mat case offers a lower per-mat cost and is ideal for facilities with multiple entry points, high mat turnover, or those that prefer to stock a larger supply to reduce reorder frequency. If you have a single entry point with moderate traffic, a 4-mat case may be sufficient. For multi-door facilities or high-traffic environments, the 8-mat case is the more economical choice.
Why is blue a common color choice for cleanroom sticky mats?
Blue mats provide high visual contrast against light-colored floors, making it easy to see when the top layer is soiled and needs to be peeled. This helps facilities maintain consistent contamination control protocols without guesswork. White mats are also available for environments where floor aesthetics or specific color-coding requirements apply.
How do I properly position a 36x45 mat at an entryway?
Place the mat with the 45-inch dimension running parallel to the direction of travel so personnel take at least one full step on the adhesive surface. For double-door entries or wider openings, consider using two mats side by side. Secure the mat with a frame if needed to prevent shifting under heavy foot traffic or wheeled equipment.
Is this mat compatible with standard adhesive mat frames?
Yes — the 36" x 45" size is compatible with standard frames designed for that footprint. Purus also offers dedicated EnviroTack frames. Contact MTE Solutions if you need help selecting the right frame for your entryway configuration.
