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

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

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

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

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

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

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

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

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

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

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

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

Cost and People Analysis Stucco & EIFS Hand Mixing - $ Batch Mixing - $$ Continuous Mixer - $$$ Cost $200 - $500 for hand mixer (drill, bucket) $2,000 - $8,000 per batch mixer $6,400 - $15,000 per continuous mixer Mixing Transporting Material 5 people (3 mixers) 4 people (1 batch mixer) 3 people (1 continuous mixer) Bags/ Hour 15-35 20-35 35-40 Cost Estimate Equipment Labor ($25/hour) Time (175 bags) Total $1,500 $ 125 10 hours $ 1250 $3,000 $ 100 5 hours $ 500 $6,400 $ 75 $ 375

Applying stucco & EIFS

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

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

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

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

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

Spray overhead without getting tired

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

Cost and People Analysis Stucco Hand Applying Large Pump Small Pump Equipment Cost $500-1,000 $25,000-30,000 $8,000-10,000 Cost per square yard $3 per sq. yard per coat $1.50 per sq. yard per coat Crew size 8 people 10 people 5 people If using a 10-man crew, can now do two jobs at once. Bags/ Hour 20 45-80 35-40 EIFS – Will do it in half the time with a pump.

The Future

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

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
