Plastic sheeting for construction and agriculture

Plastic sheeting is used in a variety of applications in the construction and agriculture industries. In construction, plastic sheeting is used for covering items during remodelling, creating construction enclosures, and forming remediation and greenhouse covers. For agricultural applications, plastic sheeting is used to protect crops, control erosion, and preserve feed.

The thickness of plastic sheeting is typically measured in mils, where 1 mil is equal to 1/1000 of an inch. The thickness of the plastic sheeting used depends on the application. For construction and greenhouse applications, plastic sheeting thicknesses typically start at 4 mil and can go up to 20 mil for the heaviest-duty applications. For example, a 6 mil plastic sheet is often used for construction enclosures and temporary covers, while a 20 mil sheet is used for waste landfill liners and outdoor storage covers.

In agriculture, thinner plastic sheeting is often used. For example, 2, 3, or 4 mil plastic sheeting can be used to cover pallets, machinery, and other large items. Thicker plastic sheeting is also used in agriculture, with 6 mil being used for greenhouse covers, and 20 mil being used for aquaponic liners.

Reinforced plastic sheeting is also available, which combines heavy-duty polyethylene with a high-strength cord to create a lightweight, durable material that won't rip or tear. This type of sheeting is often used in construction and agriculture applications where a durable but lightweight solution is needed, such as enclosures, temporary covers, and liners.

Heavy-duty plastic sheeting

A 6 mil reinforced film can be considered heavy-duty when used for covering objects, such as during remodelling or construction. However, the same 6 mil sheet would not be strong enough for lining a landfill. Therefore, it is important to consider the specific application and requirements when selecting the thickness of heavy-duty plastic sheeting.

For example, the Dura Skrim 20 mil reinforced plastic sheeting is suitable for both indoor and outdoor heavy-duty construction and agricultural use due to its highly durable nature. It combines heavy-duty polyethylene with a high-strength cord, resulting in a lightweight yet tear-resistant material.

In addition to thickness and durability, other factors to consider when selecting plastic sheeting include UV protection, flame retardancy, colour, and chemical resistance. For instance, clear sheeting provides visibility, while black sheeting offers a more discreet cover. Flame-retardant plastic sheeting is essential for meeting fire safety standards on construction sites or event setups.

Thickness for different projects

The thickness of plastic sheeting required depends on the job it will be used for. For instance, a six mil reinforced film can be considered "heavy-duty" when used to cover a desk to protect it from dust. However, the same sheet would not be thick enough to line a landfill. Other factors to consider when choosing the thickness of plastic sheeting include the strength and thickness of the film, its composition and additives, and its chemical makeup.

For projects that require a vapor barrier, a 6 mil plastic sheeting is commonly used and can be purchased from The Home Depot. This thickness is also suitable for covering desks to keep them clear of dust.

Thicker plastic sheeting, such as 10 mil and 12 mil, is often used for grain storage covers and crawl space liners. The 10 mil plastic sheeting is available from Walmart and is described as heavy-duty, tear-resistant, and a vapor barrier. The 12 mil plastic sheeting is available from Global Plastic Sheeting and offers exceptional tear resistance and seam strength. It also provides UV protection and can be used for grain storage covers, crawl space liners, pond covers, and erosion control.

For even thicker plastic sheeting, a 20 mil option is available, although specific project applications were not readily apparent.

HDPE plastic

HDPE, or high-density polyethylene, is a type of plastic sheeting that offers heavy-duty protection for a variety of applications. It is a versatile material with a range of thicknesses, making it suitable for both commercial and residential use.

For construction and greenhouse applications, HDPE sheeting thicknesses typically start at 4 mil, with 6 mil being a standard option for heavy-duty protection. Thicker options are available, with some suppliers offering HDPE sheeting in thicknesses ranging from 30 mil to 100 mil. These thicker variants are often used for landfill liners, foundation wall vapour retarders, and outdoor storage covers, where durability and puncture resistance are crucial.

Overall, HDPE plastic sheeting is a reliable and versatile option for projects requiring heavy-duty protection. With a range of thicknesses available, HDPE plastic can be tailored to specific needs, ensuring successful project outcomes in construction, agriculture, and residential applications.

Cleaning and maintenance

The thickness of plastic sheeting is typically measured in "mils", which are "one-thousandths of an inch". The thickest plastic sheeting commonly available ranges from 30 to 100 mils, with some suppliers offering sheeting up to 200 mils thick. These thicker sheets are often used for heavy-duty applications such as landfill liners, outdoor storage covers, and construction enclosures.

To ensure the longevity and clarity of thick plastic sheeting, proper cleaning and maintenance are essential. Here are some detailed instructions for cleaning and maintaining your plastic sheeting:

Identify the Type of Plastic:

Different types of plastics have specific cleaning requirements. For instance, polycarbonate sheets require dedicated cleaners like Novus #1, while acrylic sheeting can be cleaned with commercial plastic cleaners or mild soap and water.

Choose the Right Cleaning Tools:

Avoid using abrasive or dry cloths, paper towels, or your hands to wipe the plastic. Instead, opt for non-abrasive, soft, lint-free, or microfiber cloths. These cloths should be dampened with clean water or a mild cleaning solution.

Remove Surface Debris:

Before applying any cleaning solutions, it's important to remove dust, dirt, grime, oils, and other surface debris. You can blow off the debris or use a soft cloth dampened with water to gently wipe it away.

Clean the Surface:

Spray or apply a mild cleaning solution, such as warm water and dish detergent, to the surface. You can also use commercial window or multi-surface cleaners, but always test on a small area first to ensure they don't leave streaks or add cloudiness. Gently scrub the surface with a circular motion, then rinse with clean, cool water and dry with a soft cloth.

Address Cloudiness and Scratches:

If your plastic has become cloudy or scratched, you can use dampened sandpaper to scrub the surface gently. Follow this by using an abrasive polishing compound to smooth out the plastic. For scratches on acrylic sheeting, you can use plastic polish, car polish, or automobile wax with a microfiber cloth.

Remove Tough Residues:

For tough grease, oil, or tar residue, use commercial-grade hexane or kerosene. Always wipe these solvents clean with fresh water and blot dry to prevent water spotting.

Avoid Harmful Cleaners:

Never use harsh solvents or cleaners containing ammonia, acetone, carbon tetrachloride, or gasoline on plastic sheeting. These can damage the surface and reduce the lifespan of the plastic.

Prevent UV Damage:

Prolonged exposure to ultraviolet rays from the sun can cause discolouration and haze on plastic sheeting. To mitigate this, consider applying a UV clear-coat spray or commercial protective wax after cleaning. Additionally, choose sheeting with UV protection additives if it will be exposed to sunlight.

Regular Maintenance:

To maintain the clarity and integrity of your plastic sheeting, regularly clean it using the methods mentioned above. Additionally, reduce static electricity buildup by using an anti-static cleaner for plastics, especially if the sheet is placed indoors, as this can attract dust and dirt.

By following these detailed instructions, you can effectively clean and maintain your thick plastic sheeting, ensuring its longevity and optimal performance.
