Hamilton vs Purdy Dust Sheet

What is the Hamilton Dust Sheet?

Hamilton dust sheets are typically made from lightweight polyethylene plastic. They are designed for quick, single-use protection against dust, paint splatter, and dry debris. Their primary advantage is being completely waterproof, making them ideal for protecting floors from wet paint drips or for covering furniture during messy demolition work. They are often sold in rolls or multi-packs and are very affordable.

What is the Purdy Dust Sheet?

Purdy dust sheets, specifically their canvas drop cloths, are the professional standard. Made from heavy-duty 100% cotton canvas, they are designed for repeated use. The fabric is highly absorbent, which prevents paint drips from running and spreading. A key feature is their non-slip backing, which keeps the cloth in place on ladders and floors, reducing trip hazards. They are heavier, more durable, and more expensive than plastic sheets.

Material and Durability: Canvas vs. Polyethylene

The core difference lies in the material. Purdy's canvas is a woven fabric that is thick and durable. It can withstand being walked on, folded, and washed multiple times without tearing. Owner reviews frequently note that a single Purdy canvas cloth can last for years of professional use. In contrast, Hamilton's polyethylene sheet is a thin plastic film. While it is tear-resistant to a degree, it is not designed for heavy foot traffic or reuse. A single snag or sharp object can ruin a plastic sheet.

Waterproofing and Spill Management

This is a critical trade-off. Hamilton plastic sheets are 100% waterproof. They are excellent for containing wet paint or water spills, as the liquid will pool on top. However, this can be a hazard if the puddle is not cleaned up quickly, as it can be stepped in. Purdy canvas cloths are not waterproof. Instead, they absorb liquid spills, soaking up paint drips and preventing them from spreading across the floor. This absorbency is preferred by many painters as it keeps the work area safer and cleaner. For drywall dust or sanding debris, plastic is easier to clean by simply gathering the corners.

Safety and Slip Resistance

Safety on a job site is paramount. Purdy canvas drop cloths have a natural non-slip texture that grips the floor and stays put under ladders. This is a major selling point for professionals. Hamilton plastic sheets are very slippery, especially on smooth floors like hardwood or tile. They can pose a significant slip hazard if not taped down. For this reason, many contractors strictly use canvas for floor protection.

What to Check Before Buying a Dust Sheet

Before purchasing, consider the specific task. For painting ceilings or walls where drips are likely, a canvas cloth is safer and more effective. For covering large furniture or protecting against dust from sanding, a plastic sheet is more practical and cheaper. Check the weight of canvas cloths (measured in ounces per square yard); 12 oz is a common heavy-duty standard. For plastic, look for mil thickness (e.g., 2 mil, 4 mil); higher mil means thicker, more durable plastic.

Mistakes to Avoid

A common mistake is using a plastic sheet on a floor where you will be walking with wet paint on your shoes. The paint can transfer to the plastic and then to other areas. Another error is using a lightweight canvas cloth (under 8 oz) for heavy-duty protection, as it may not absorb enough liquid or resist tearing. Finally, never use a plastic sheet on a ladder platform; it is extremely dangerous due to slippage.
