Cleanroom Tacky Mats: Installation and Maintenance Guidelines


Cleanroom tacky mats are an essential tool in controlling contamination within sensitive environments such as cleanrooms, laboratories, and manufacturing facilities. These mats effectively trap dust, dirt, and other contaminants on their sticky surface, preventing them from spreading and compromising the integrity of the controlled environment. However, for optimal effectiveness, proper installation and regular maintenance of tacky mats are crucial. In this article, we will provide comprehensive guidelines on the installation and maintenance of cleanroom tacky mats, ensuring that their performance is optimized and contamination risks are minimized.

I. Understanding Cleanroom Tacky Mats:

Cleanroom tacky mats consist of multiple layers of adhesive sheets that are placed on the floor or entrance of a controlled environment. Each sheet has a specified number, typically starting from 30 or 60, indicating the number of layers. These adhesive sheets capture various types of contaminants, including footborne particles, lint, and dust, preventing them from tracking into cleanroom areas.

II. Selecting the Appropriate Position for Tacky Mat Installation:

To achieve maximum effectiveness, proper placement of tacky mats is crucial. Here are some guidelines to help you choose the most suitable positions for installation:

1. Entryways and Exits:

Placing tacky mats at entry and exit points is essential to prevent contamination from entering or exiting a cleanroom. Ensure that the mats completely cover the entrances, allowing individuals to walk across them without stepping on the surrounding floor.

2. High-Traffic Areas:

Identify areas with high foot traffic or where the chances of contamination transfer are increased, such as changing rooms or gowning areas. Installing tacky mats in such locations helps mitigate the risk of contamination, particularly when cleanroom personnel change their shoes or garments.

3. Cleanroom Interiors:

Depending on the specific requirements of the cleanroom, some organizations choose to install tacky mats within the cleanroom itself. This approach can be particularly effective when the cleanroom has multiple zones with varying cleanliness levels.

III. Proper Installation Procedure:

Once the appropriate positions for tacky mat installation have been identified, proper installation techniques should be followed. Here's a step-by-step guide to ensure correct installation:

1. Clean and Prepare the Floor:

Thoroughly clean the designated area where the tacky mat will be installed. Remove any debris, dust, or other particles to ensure optimum adhesion.

2. Mark the Position:

Using masking tape or an alternative non-residual marking method, mark the floor to indicate the exact position where the tacky mat will be placed. Proper alignment is crucial.

3. Place the First Layer:

Peel off the protective film from the adhesive layer of the first sheet and carefully press it onto the marked position. Ensure that it adheres firmly to the floor, avoiding any air bubbles or wrinkles.

4. Add Additional Layers:

For mats with multiple layers, repeat the process by carefully peeling off the adhesive film from each new sheet and placing it on top of the previous one. Press firmly to ensure a secure bond between each layer.

IV. Maintenance Guidelines for Cleanroom Tacky Mats:

Regular maintenance is vital to preserve the effectiveness and longevity of tacky mats. Failure to follow proper maintenance procedures can lead to reduced adhesive performance and compromise the cleanliness of the controlled environment. Here are some essential maintenance guidelines:

1. Regular Inspection:

Inspect the tacky mats daily to ensure they are in good condition. Check for visible signs of contamination, tears, or damage. If any issues are found, replace the affected layer or the entire mat if necessary.

2. Scheduled Replacement:

Establish a schedule for replacing the tacky mats based on the level of foot traffic and contamination within the cleanroom. High-traffic areas may require more frequent replacement than lesser-used zones.

3. Contaminated Layer Removal:

When a layer becomes saturated with contaminants, carefully remove it from the mat using designated pull tabs or designated pulling direction specified by the manufacturer. Dispose of the removed layer safely and appropriately.

4. Cleaning the Mat Surface:

To maintain optimal adhesive performance, clean the surface of the tacky mats regularly. Use the recommended cleaning solutions or static control products provided by the manufacturer. Avoid using abrasive materials that may damage the mat's sticky surface.

V. Training and Awareness:

Proper training and awareness among cleanroom personnel are key elements in ensuring the effectiveness of cleanroom tacky mats. Educate staff on the importance of adhering to the guidelines mentioned above. Emphasize the significance of stepping correctly on the mats to maintain cleanliness during entry, exit, and movement within the cleanroom.


Cleanroom tacky mats play a vital role in preventing contamination within controlled environments. Proper installation and regular maintenance are essential to maintain their efficacy. By following the guidelines provided in this article, organizations can ensure the optimal performance of cleanroom tacky mats, thereby safeguarding the integrity of their cleanroom environments and protecting critical processes from contamination risks.
