It’s needless to say that our Sales Team knows a thing or two about finishing swimming pools. We’ve decided to expand our “Ask an Applicator” series to “Ask a CLI Pool Pro.” This edition’s question is fielded by Mr. Tom Martin. Tom has served our customers for nearly 15 years as a regional sales manager covering nearly every state east of the Rockies.
Our question comes from Danny at Medallion Pool in Asheville, NC. They design and build some of the most stunning backyard living environments we’ve ever seen.
Hello guys…I have a customer with a larger overflow wall (infinity edge pool) and trough. The trough is finished in natural stone and has developed a leak. The stone has to come off in order to find and repair the leak. As part of future leak prevention to reduce labor and home preference, we were exploring the idea of putting a pebble aggregate plaster on the overflow wall and trough. I’ve heard from other manufacturer reps that pebble shouldn’t be out of the water. Some other aggregate installers I’ve spoken with say it can, thus the use on beach entries, etc. The overflow is scheduled for a few hours during the day (as part of daily operation), and full operation if in use. So there will be some time the wall would not be covered in water (as opposed to falling water). Would one of your products (pebble or other) function well in this situation?
Hi Danny, unfortunately no plaster manufacture I’m aware of warranties finishes above the water line, but with that being said, it is still done. Make sure you plaster in spring or summer to allow max cure time before being drained.
Follow the steps below for optimal performance.
- Apply Permakote waterproofing to substrate before plastering (See next article for PermaKote Installation Guidelines)
- Use larger aggregate finishes such as CrystalStones Natural or Hydrazzo Classico.
- Use the strongest mix possible (Do not over water plaster mix, sometimes a watered down mix is used for a scratch coat)
- Hard Trowel to drive out all water.
- Once plaster is applied and exposed use Soaker Hoses (available at garden stores) or concrete blankets/sprinklers to keep plaster wet for as long as possible… 28 days would be nice.. minimum 14 days unless in Ultra cold climes like Wisconsin/ Maine then shoot for 28 days.
- A tile break is advisable in case of failure, so you can chip out and replace a small section.
- Use an Authorized CL Industries Applicator for plastering.
