1. Advancements to Mixing and Moving Stucco and EIFS
Presenter: Bryce Gapinski, Product Manager, ToughTek Mortar Equipment, Graco

2. Agenda Shifts in the market Comparison of mixing techniques
Applying stucco and EIFS
What does the future have in store?

3. Labor Pool Smaller Now Than in the Past
Finding new people entering the trades
Educating employees
Limited resources
With a pump, you can have a smaller crew at one jobsite.
Education: Potential set-backs on site if something is mishandled
Finding new people entering the trades
Educating employees
Difficulty organizing where to send people or don’t have enough for a job

4. Preblended Materials Gaining Traction
Spec’d in because less room for error
City regulations and Silica Rule
Smaller footprint on site
Material suppliers actively promoting material

5. For every job that requires material, you need to mix them.
Mixing

6. Hand Mixing Pros: Least expensive option Most widely available
Versatile
Does not require preblended material
Easy to clean and maintain

7. Hand Mixing
Cons:
Water variability (inconsistent mix from bag to bag or operator to operator)
Manual process that can cause personal injury
Slow production
Messy

8. Batch Mixing Pros: Automated process that mixes the material
Higher production than hand mixing
Widely available and easily rented
Common in gas and 120V power options
Does not require preblended material

9. Batch Mixing Cons: Material mix variability
Takes time to mix batch to batch
Medium production
Potential for operator to injure themselves while dumping and motor is running

10. Continuous Mixer Pros:
Automated mixing of water and preblended materials
Highest output option
Least amount of variability in material mixing
Easily dumps into wheel barrel or pump so operation can continuously apply material
Least manual process, helping to prevent operator injury
Safest option for operator

11. Continuous Mixer Cons: Only mixes preblended materials
Most expensive option
Requires a dedicated water source

12. New continuous mixers are entering the market, however…
Simpler to use
Less expensive
Only need 120V power source

14. Applying stucco & EIFS

15. Hand Applying Pros: Less equipment Less setup time
No power requirements
Contractor controls application
Cons:
More labor intensive
Slower production

16. Pumping – Perceptions in the Market
Quality issues – go too fast, work won’t be as good
Messy or difficult to learn
Expensive and difficult to maintain

17. What’s the biggest difference?
Large Pump
Must be towed behind truck
Weighs 2000 – 4000 lbs
Small Pump
Small and portable – can be loaded into pickup truck
Weighs 200 lbs

18. Large Pump Pros: Twice as fast as hand applying Very high production
Familiarity of equipment
Cons:
Equipment is large and heavy
Takes larger crews to keep up with machine
High pressures can be dangerous

19. Small Pumps Pros: Faster than hand applying
Smaller crew size than large pump
Portable
Ease of operation
Faster than hand applying
Smaller crew size while maintaining same production per person as large pump
Portable - Easy to transport and can take into building on any floor
Ease of operation

20. Spray overhead without getting tired

21. Small Pumps Cons: Less production than large pump
Less familiarity (in the market) with pump and its capabilities

25. The Future

26. Market Shifts Aging infrastructure Tighter deadlines to get jobs done
Future codes and regulations (state and country levels)

27. Shift to Smaller Pumps and More Efficient Mixers
Newer pumps have higher pressures than they used to have
Require smaller crew sizes
Foot prints of job sites are getting smaller
Newer pumps have higher pressures than they used to have (small piston pumps will produce 600 psi of pressure)
Require smaller crew sizes
Foot prints of job sites are getting smaller
