Scotchgard Heavy Duty Water Shield
Scotchgard’s Heavy Duty Water Shield stands out as a reliable option for farm canvas applications. This aerosol-based sealant delivers consistent coverage and penetrates deep into canvas fibers.
Superior Water Repellency for Canvas Materials
You’ll notice immediate beading action after applying Scotchgard to your canvas tarps. The formula creates a protective barrier that repels water while maintaining the fabric’s breathability.
