SERVICE 3214: Plaster Startup Chemistry
Wednesday, January 13, 2027
1:00 - 5:00 PM
0.4 IACET CEUs | Duration: 4 hours
The moment water begins to fill a freshly-plastered watershape, chemical reactions are taking place. Too often, the tap water chemistry and cement chemistry interact to cause frustrating discolorations and other plaster problems. This course covers basic cement and water chemistry, and walks through how to prevent such issues before they start.

E2731: Structural Repairs of Existing Pools (Spanish)
8:00-9:00 AM
0.1 IACET CEUs | Duration: 1 hour
Implementing the wrong type of structural repair can lead to even more costly repairs. Therefore, it is imperative to understand the failure type and develop a suitable repair that will fix the original defect without creating a new one. Some common repairs in the industry such as epoxy or staples simply don’t work in certain situations. This program will expose you to some common myths and show preferred repair methods.
Instructor: JC Escudero, IWI
D1941: The Challenges of Historical Preservation
8:00-9:00 AM
1.6 IACET CEUs | Duration: 16 hours
Some watershapes have existed for thousands of years. Some have literally fallen apart in just a few decades. Why has new technology failed where seemingly ancient projects have stood the test of time and the challenge of the elements? More importantly, what can watershapers do to inject new life into old projects while maintaining the historical performance, materials and character? Historical preservation is challenging but rewarding and much of this work is being done outside of the watershaping industry even though water is a key element of the project. Tune-in to find out why and how you might get involved with one of these projects.
Instructor: Mike Nantz, IWI
B1341: Design Fees - Billing for Professional Services
9:15-10:15 AM
0.1 IACET CEUs | Duration: 1 hour

Overcome the fear that charging for design and estimates may lose you the job. Think of your efforts as any other professional, be it Doctor, Lawyer or Accountant, charge for your services!
