What is  Hot Mop?

A hot mop is the process of waterproofing with hot asphalt and roofing paper. The application can be used in many different projects. The most common is hot mopping of shower en-closers, decks, roman tubs, and retaining walls. Each hot mop application is specific to the job.

Preparing a shower for Hot Mop

• Blocking: Solid blocking must be installed between the studs of the shower walls, extending a minimum of 8 inches up the walls.
• Curb: A shower en-closer must have a curb/dam. The curb is what you step over when entering the shower enclosure. It is also what stops the water from exiting the shower. A minimum curb height of 6 inches or 3 (2x4s laid flat) is required. Note: There may be exceptions made for handicap showers.
• Two Piece Hot Mop Drain: There are multiple drains that can be purchased, from plastic to cast iron. Drain selection is based on your specific need. The bottom flange of the two piece drain should be set level with the concrete slab or wood sub-floor.
• Water Testing: Water testing ensures you get what you payed for. A water test should be done on every shower to ensure that there are no leaks. Leaks can be found by placing a drain plug inside your two piece hot mop drain, and filling the shower pan. Although very few shower pans leak (if properly installed) a water test gives piece of mind.
• What to expect:  The smell of asphalt may linger for an hour or more and ventilation of the shower stall will reduce the overall smell. Approximate time for completion is roughly 2 hours, with a cure time of 1 hour. All flooring around bathroom  and job should be protected and extreme caution is always taken from our installer.
