Why Professional Gun Foam:

• Better Control: Foam gun provides precise application and flow control
• More Economical: Large 28.6 oz cans offer better value than small straw cans
• Reusable System: One gun works with multiple cans—no waste
• Professional Results: Consistent foam quality and application
• Adjustable Flow: Control foam output for different applications
• Less Waste: Use only what you need, save rest for later

Common Applications:

• Waterfall construction—filling voids between rocks
• Directing water flow over spillways and cascades
• Sealing cracks and gaps in rock formations
• Securing rocks in place during construction
• Creating water channels and directing streams
• Building up areas for optimal water sheet flow
• Filling spaces around skimmers and plumbing
• Pond edge sealing and rock stabilization

Professional Foam Gun Benefits:

• Attaches directly to foam can for continuous use
• Trigger control for precise foam dispensing
• Adjustable flow rate for different applications
• Reusable—works with hundreds of cans over time
• Reduces hand fatigue on large projects
• Professional-grade construction for durability

Why Foam Gun Cleaner is Essential:

• Prevents foam from curing inside gun and causing permanent clogs
• Extends foam gun lifespan indefinitely with proper maintenance
• Clean gun between cans and after each use
• Attaches directly to gun for internal flushing
• One cleaner can provides multiple cleanings

Specifications:

• Can size: 28.6 oz (750 ml) per can
• Color: Black (for natural appearance in water features)
• Type: Professional gun-grade expanding polyurethane foam
• Application: Requires professional foam gun (included in some kits)
• Expansion: High-expansion formula
• Cure time: Tack-free in 30-60 minutes, full cure in 24 hours

Choosing Your Kit:

• First waterfall project: Choose 6-count with gun kit
• Small to medium waterfall: 6-count with cleaner (if you have gun)
• Large waterfall or multiple projects: 12-count with cleaner
• Professional contractor: 12-count with gun for new equipment
• Refill only: 6-count or 12-count foam only (if you have gun and cleaner)

Important Maintenance:

• Always clean foam gun immediately after use with Pur Clean
• Never let foam cure inside gun—it will permanently clog
• Store gun with cleaner can attached to keep channels clear
• Clean gun between foam cans during extended projects

Note: Professional gun foam provides superior control and economy compared to disposable straw cans. The initial investment in a foam gun pays for itself quickly through better foam value and reusability. Always purchase cleaner with your foam—a clogged gun is expensive to replace. For fish safety, allow foam to fully cure (24-48 hours) before filling pond with water.

Frequently Asked Questions

Q: What's the difference between gun foam and the straw foam cans?
A: Gun foam (like this Pur Black) comes in large 28.6 oz cans that attach to a reusable professional foam gun, while straw foam comes in small 16 oz cans with disposable straws. Gun foam offers much better value—you get nearly twice the foam per can at a lower cost per ounce. The foam gun also provides superior control with adjustable flow, trigger operation, and the ability to stop and start without waste. Once you invest in a gun, you can use it with hundreds of cans over the years. Straw cans are convenient for very small, one-time projects, but gun foam is the professional choice for waterfall construction and anyone doing more than minimal foam work.

Q: Which kit should I buy for building my first backyard waterfall?
A: For a first waterfall project, we recommend the 6-count kit with foam gun included. This gives you everything you need to get started: 6 large cans of black foam (plenty for most residential waterfalls) and a professional foam gun. You'll also want to add at least one can of Pur Clean cleaner (sold separately or choose the kit with cleaner) to maintain your gun. The 6-count provides enough foam for a small to medium waterfall while letting you learn the technique. You can always purchase additional foam cans later if needed. If you're building a large waterfall (over 6 feet tall or very wide), consider the 12-count kit.

Q: How important is the foam gun cleaner, and can I skip it to save money?
A: Foam gun cleaner is absolutely essential—never skip it! If you let foam cure inside your gun, it will permanently clog and you'll need to buy a new gun (which costs more than cleaner). Clean your gun immediately after every use and between foam cans during long projects. The cleaner attaches directly to your gun and flushes out uncured foam before it hardens. Think of it as cheap insurance for your foam gun investment. The kits that include cleaner are the smart choice—you get the right ratio of cleaner to foam. As a rule of thumb, one can of cleaner provides enough for cleaning after using 6-8 foam cans, so the 6-count kits include 1 cleaner and 12-count kits include 2 cleaners.
