What is the Zipper (For Mylar, Tarps & Greenhouses) used for?
It’s a peel-and-stick zipper strip designed to turn plastic sheeting—like mylar, greenhouse film, or tarps—into a usable zippered doorway or access hatch. Common uses include grow room walls, greenhouse doors, dust barriers, and temporary enclosures.
How long is the zipper, and can it be cut or combined for larger openings?
Each zipper strip is 2.1 metres long and can be trimmed to suit shorter doors. For wider entries, use two zippers spaced apart to create a roll-up or double-door style opening.
How do I install the Zipper properly?
Stick the zipper onto clean, dry plastic, unzip it, and then cut your opening inside the zipper area using a sharp utility blade. Installing on a flat or tensioned surface helps prevent wrinkling and ensures better adhesion.
What surface prep is needed before applying the zipper?
The surface must be clean and dry—dust, moisture, or cold temps reduce adhesion. Avoid applying to wrinkled, oily, or dirty surfaces. For textured plastics, test first or reinforce the edges if needed.
Is the Zipper weatherproof and suitable for outdoor use?
It’s commonly used outdoors on greenhouses, tarps, and covers. However, long-term exposure to UV, wind flex, or temperature swings can weaken the adhesive over time. For best results, reinforce if used in extreme conditions.
Will the Zipper block light and seal air or odours?
It helps reduce light and airflow through access points, but full lightproofing or airtight sealing depends on how well you overlap, seal, or reinforce the surrounding plastic. For strict environments, add flaps or tape as needed.
Can the Zipper be opened from both sides?
Some versions allow dual-side access, but most are one-sided. Plan to install it so the zipper pull is accessible from the side you use most. For two-way access, use two zippers in a curtain-style entry.
How do I keep the zipper door open when needed?
You can roll up the flap and secure it with clips, ties, or Velcro straps. This is useful for carrying gear through or ventilating the area temporarily.
How do I prevent tearing or wear around the zipper opening?
Use a clean, straight cut and avoid sharp corners. You can round the corners or reinforce the plastic edge with tape. High-traffic areas may need extra support to prevent stretching or failure over time.
Can I create small service hatches or zone dividers with the Zipper?
Yes—many people use it for quick-access hatches inside grow room partitions or renovation barriers. You’re not limited to full doors; a small zipper cutout works great for checking equipment or isolating zones.
Will the Zipper stick to any plastic sheeting?
It sticks best to smooth, clean surfaces like mylar, poly sheeting, shrink wrap, or clear PVC. Adhesion is less reliable on textured, dusty, or waxy plastics. Always test before committing to a full install.
How do I get the best adhesion from the Zipper?
Ensure the surface is clean and dry, press the adhesive strip firmly along its full length, and avoid repositioning once stuck. Tensioned or flat surfaces help maintain a strong hold over time.
Can the Zipper be removed or reused?
It’s considered semi-permanent. Removal can leave residue or stretch thin films. It’s not reusable once removed, so plan placement carefully and remove slowly if needed to avoid tearing plastic.
Is this only for grow rooms, or are there other uses?
Beyond grow rooms, it’s great for boat covers, greenhouses, renovation dust barriers, caravans, patios, and even temporary sheds. Any clean plastic sheeting can become a doorway with this zipper.
What’s the most common mistake when installing the Zipper?
Applying it to dirty, wet, or loose plastic without cleaning or tensioning the surface. For best results: clean thoroughly, tension the plastic, press down firmly, and cut carefully after sticking.
