Scope Of Work

Skeptics Turn Converts

When Heminokeky was recruited to the Clear Penetrating Sealer development team, he was a vocal

skeptic. His former job had convinced him that water repellant work was tedious and expensive.

“Clear water repellants are two types,” Heminokeky explained. “They are either fi lm formers or

penetrating water repellants. Both come with a lot of baggage. In most cases, there is a strong chance

you will have to evacuate buildings because of the fumes and odors produced by the solvents in the water

repellant. Overspray can kill or damage vegetation and the products can etch glass windows and damage

metal. So you have to tarp and tape the landscaping and windows, and you’d better make sure cars are

parked far away or covered!”

Added labor for tarping and taping landscaping and windows adds to the cost of the job. But on high-rise

buildings, the real expense lies in the fact that contractors essentially have to mobilize a swing stage or man

lift, power wash, de-mobilize the lift, and re-mobilize two-to-three days later when the substrate is dry.

“None of the products on the market today can be applied to damp surfaces,” Heminokeky. “So fi rst you

power wash the masonry in sections, moving the swing stage as you go. Then you wait several days for

the surface to dry. Once it’s dry, you start all over and apply the sealer. These jobs are a big hassle.”

Greene, too, was in the “hassle” camp when it came to water repellant sealers. “The initial prep covering

windows and plants is really time consuming, especially on multi-story buildings. Then you have to

remove it all. The most commonly used sealers are solvent based, so you have to use special precautions

to make sure the product doesn’t overfl ow into streets or onto vegetation. Plus these products are

packaged in drums making them hard to move around and they also create a lot of jobsite waste. These

jobs are a pain and they’re not that profi table at the end of the day.”

In June, Heminokeky and Greene loaded one 20 liter container of Clear Penetrating Sealer into the back

of a truck, rented a lift and headed to Rhome. Th

e hardened skeptics determined to put Clear Penetrating

Sealer product claims to the test on the historic brick structure. Already a believer based on extensive

laboratory tests, Velten simply observed.

As Greene power washed the surface, Heminokeky followed directly on his heels, applying the Clear

Penetrating Sealer even as the water was dripping to the ground. He sprayed windows. Greene washed

them off. No surface was safe, including metal and plastic. The pair even sprayed Clear Penetrating

Sealer on the day lilies. (Velten happily reported a month later the thriving plants had to be cut back

because of overgrowth.)

“This wasn’t a multi-story building, but being able to mobilize once is a huge deal,” Greene said. “You set

up the swing stage, clean and seal in one shot. That’s a huge time and money saver.”

“I told the sealer development team I was going to try to make this product fail,” Heminokeky said.

“Bottom line? I couldn’t. I mean parts of this 75-year old building were black with grime. Today it looks

as good as new.”

Another Clear Penetrating Sealer convert? Reverend Utz.

“We are very pleased that your company selected the Rhome Church for a fi eld trial of your Clear

Penetrating Sealer,” he wrote in a thank-you note. “There was no discoloration. There was no

inconvenience to the church’s schedule. The benefi t will be in the water proofi ng and the preservation

quality of your product. Our church members are very grateful that their historic church building has been

maintained for future generations.”
