Painting — FAQ
What's the ideal canvas weight for wall painting?
8-10 oz canvas provides optimal protection for most wall projects. Heavier 12 oz tarps suit commercial work or repeated use. Lighter 6 oz risks bleed-through on porous surfaces like unfinished hardwood.
How do I prevent paint from bleeding through to carpet?
Use 10 oz or heavier canvas, and fold the tarp double in high-risk areas. For maximum protection, layer a canvas drop cloth over rosin paper. Immediately wipe spills rather than letting paint pool.
Can canvas drop cloths be machine washed?
Yes, but expect 3-5% shrinkage after the first wash. Use cold water and avoid high heat drying. Washing actually improves protection as fibers swell tighter. Shake out dried paint chips before laundering.
Are canvas tarps better than plastic for walls?
Canvas absorbs spills, preventing pooled paint from tracking onto shoes. Plastic slips on hard floors and tears easily. Use canvas for flooring; plastic sheeting works for covering furniture where slipping isn't a hazard.
How many drop cloths do I need for a room?
One 9x12-foot tarp covers average room floors. Add a 4x12-foot cloth for wall runs and ladder protection. For whole-house projects, calculate one 9x12 per room plus one 4x12 for hallways.
Why do double-stitched edges matter?
Double stitching prevents fraying that leads to tripping hazards and reduces lifespan. It maintains the tarp's shape after washing and provides reinforcement where stress concentrates. Inspect stitching density—loose threads indicate poor construction.
