Frequently Asked Questions
Can I apply NetZero Liquid Rubber waterproof sealant over existing coatings?
Yes, NetZero Liquid Rubber can be applied over most existing coatings, but the surface must be clean, dry, and in good condition.
What tools do I need to waterproof my roof?
Use a paintbrush, roller or spray machine for larger roofs. Basic safety gear such as gloves is recommended.
Should I coat the entire roof with NetZero Liquid Rubber?
In most projects you only need to seal problem areas: rusty patches, seams and joints, around skylights and vents. Targeting these areas stops leaks while saving time and materials.
How do I prepare the surface?
Use a power washer to clean the surface. It must be clean, dry, and free of loose paint, rust, and contaminants.
How many coats should I apply?
Apply a minimum of two coats of NetZero Liquid Rubber waterproof sealant. The amount in the Kit Builder is enough for 2–3 coats.
What are the drying and curing times?
Allow each coat to cure for 12 to 24 hours before re-coating (full cure in 72h depending on weather).
