# Frequently Asked Questions - Cement Sheet & Blueboard Green Wall Screws 20pc

## Product Information

**What exactly are these Green Wall Screws designed for?**  

These high-quality class 3 coated screws are specifically designed for attaching artificial vertical garden panels (green walls) to cement sheet or blueboard surfaces. Their specially engineered wide head ensures proper attachment of the garden panels while maintaining a secure hold.

**What comes in the package?**  

Each package contains 20 pieces of self-drilling cement sheet/blueboard screws. Each screw is 20mm (2cm) in length and features a Phillips head design for easy installation.

**What makes these screws different from regular screws?**  

These screws feature a galvanized coating (class 3) that provides enhanced resistance to corrosion, making them suitable for both indoor and outdoor applications. The wide screw head is specifically designed to overlap with artificial green wall panels for secure attachment, and the self-drilling point eliminates the need for pre-drilling in most blueboard and cement sheet applications.

**What is the weight of the package?**  

The package weighs approximately 20 grams.

**Are these screws rust-resistant?**  

Yes, these screws feature a galvanized coating that provides excellent protection against rust and corrosion, making them suitable for use in various environmental conditions, including outdoor installations.

## Installation & Usage

**How many screws should I use per green wall panel?**  

We recommend using approximately 1 screw per 25cm section of your green wall panel. For a standard 1m x 1m panel, you would typically need about 12-16 screws evenly spaced for optimal security.

**Do I need to pre-drill holes before using these screws?**  

No, these are self-drilling screws designed to go directly into cement sheet or blueboard without pre-drilling. However, for very dense or hard cement boards, a pilot hole may help with installation.

**What tools do I need to install these screws?**  

You'll need a Phillips screwdriver or preferably a power drill with a Phillips driver bit for easier installation. A measuring tape or ruler is also useful for ensuring even spacing between screws.

**What's the best way to attach an artificial green wall using these screws?**  

For optimal installation:
1. Mark out the area where your green wall panel will be placed
2. Position your green wall panel against the surface
3. Insert screws through the panel's grid structure and into the blueboard/cement sheet at roughly 25cm intervals
4. Ensure the wide head of each screw overlaps with the green wall panel grid
5. Tighten until secure but avoid over-tightening which could damage the panel

**Can these screws be used on other surfaces besides cement sheet or blueboard?**  

While primarily designed for cement sheet and blueboard surfaces, these screws can also be used on other similar substrates like drywall or plasterboard. However, for masonry, concrete, or brick walls, different fasteners may be more appropriate.

**How much weight can these screws support?**  

When properly installed into cement sheet or blueboard, these screws can securely hold artificial green wall panels, which typically weigh between 2-5kg per square meter. However, for particularly heavy panels or in high-wind outdoor areas, additional support may be recommended.

## Compatibility & Applications

**What types of artificial green wall panels are these screws compatible with?**  

These screws are compatible with most commercially available artificial green wall panels that feature a grid or mesh backing structure. They work particularly well with standard 1m x 1m panels from major vertical garden suppliers.

**Can I use these screws for real (living) green walls?**  

These screws are specifically designed for artificial green wall installations. For living green walls, which typically involve different mounting systems and may require waterproofing considerations, specialized mounting hardware is usually recommended.

**Will these screws damage my cement sheet or blueboard wall?**  

When used as directed, these screws create minimal damage to your wall. The self-drilling design helps reduce the risk of cracking the cement sheet or blueboard. However, always ensure screws are driven perpendicular to the surface to minimize potential damage.

**Can I remove and reuse these screws if I need to reposition my green wall?**  

Yes, these screws can be carefully removed and reused. However, for best results, we recommend using new screws if you're reinstalling your green wall in a different location, as the threading may be worn after removal.

**Are these screws suitable for outdoor use?**  

Yes, the galvanized coating provides good protection against outdoor elements, making them suitable for both indoor and outdoor artificial green wall installations.

## Purchasing & Shipping

**Why might my order be shipped in different packages?**  

If you have a multi-item order, each item may be shipped from different international warehouses depending on availability. This approach ensures you receive your items as quickly as possible rather than holding up your entire order.

## Troubleshooting & Tips

**What should I do if the screws aren't easily penetrating the blueboard?**  

If you encounter resistance when installing the screws, creating a small pilot hole with a 2mm drill bit can help facilitate easier insertion. Alternatively, applying slightly more pressure while maintaining a slow, steady drilling speed can also help with penetration.

**How do I ensure my green wall panels look seamless when installed?** 

For a seamless appearance, ensure panels are properly aligned before securing with screws. Start from one corner and work methodically across and down. Position screws at the junction points where panels meet for a more secure and visually integrated installation.

**Can I use these screws if my wall has already been rendered or painted?**  

Yes, these screws can penetrate through rendered or painted surfaces into the underlying blueboard or cement sheet. However, be aware that installation will leave visible screw heads unless they're positioned where foliage will conceal them.

**What's the best spacing pattern for these screws when installing a vertical garden?**  

For optimal security and an even distribution of weight, position screws in a grid pattern approximately 25-30cm apart both horizontally and vertically. Pay special attention to corners and edges, which may require additional screws for proper support.
