Why Dycem?

Dycem vs. peel-off mats


Singular peel-off mat: 73% contamination enters critical environment


Ganged peel-off mat: 20% contamination enters critical environment


Dycem: <0.01% contamination enters critical environment

Independent scientific tests show that disposable adhesive peel-off mats are only 27% effective in preventing foot and wheel borne contamination. This is compared with 99.9% prevention when using Dycem Contamination Control Mats.


Five times smaller than Dycem, the average 2’x4’ sized peel-off mat is too small to decontaminate effectively, and makes full wheel-borne decontamination almost impossible. This, coupled with the usual placement of only one peel-off mat outside critical areas can be very dangerous.

Dycem can be cut to any length or width to produce a large enough surface area to allow 99.9% decontamination of foot and wheel-borne contamination.


In order to get a near comparable performance to Dycem, at least 8-10 peel-off mats, tacky mats or sticky mats need to be ganged together and peeled regularly.

Ganging peel-off mats does address the size issue. However, the practical issues, labor and material costs involved in peeling 8-10 mats several times each shift makes this an expensive option. 10 peel-off mats ganged together means there is a 20% risk of contamination entering a critical area if peeled twice per shift (Source: Mcon).

Also, when ganged together, peel-off mats can harbor contaminants in the gaps between them. Dycem is seamless, thus avoiding this contaminant trap.

Particle build up

The performance of peel-off mats is greatly reduced with overstrikes. With every step, contamination builds up in layers on feet. This buildup of contamination on feet with not be effectively removed after on or a couple of steps on that area. In addition, particles readily transfer back onto footwear, increasing the risk of contamination.

When overstriking on Dycem a further 90.3% of particles are removed from overshoes, compared with an increase of up to 381.9% being deposited back on to the shoes using peel-off mats (Source: Dr. Tim Sandle).

Wheeled traffic

Unlike Dycem, peel-off mats cannot allow the three full wheel rotations necessary to decontaminate wheeled traffic.

Peel-off mats are also prone to wrapping around wheels of trolleys and carts making it impossible to control cross contamination in corridors.

Peel-off mats are also prone to wrapping around wheels of carts or forklifts making it impossible to control cross contamination in corridors.

Peel-off mats are prone to heavy saturation very quickly, reducing their efficiency in heavy traffic environments.

Adhesive from peel-off mats can be transferred onto wheels and tracked into critical environments.

Peeling mats

A study commissioned by a peel-off mat manufacturer highlighted the problem of particle shedding during the rip up process of peel-off mats. The tests revealed that on average, 215,000 particles were released during the rip-up process – releasing hundreds of thousands of particles back into the atmosphere.

Cost comparison

The low initial cost of peel-off mats may seem attractive. However, when comparing Dycem with peel-off mats, Dycem not only costs less over the longevity of both products but, most critically, Dycem vastly outperforms in terms of size, quality and retention of decontaminants – significantly reducing the risks to your business.

Environmental impact

The hazardous/contaminated waste, coupled with disposal costs created with peel-off mats should not be ignored. With the 20cm ball of waste created when peeling off a mat layer (generating enough waste to fill multiple dumpsters per year), and also being classed as secondary waste, peel-off mats not only create an abundance of unnecessary waste but are very expensive to dispose of properly at the end of it’s very short working life.

Dycem is easily integrated into your SOP and can be cleaned as part of your regular floor cleaning schedule. Dycem does not impact on your daily waste volumes and can either be disposed of normally in regular waste or recycled into less critical applications (after its minimum 1-year working life).
