Inspector's Corner COATINGSPRO JANUARY 2018 33 There are many standards and test methods we are asked to use that don't always ensure good workmanship, and it takes a keen inspector to identif y areas of potential for poor quality outcomes. Silicate (Inorganic) Zinc-Rich Primers by Solvent Rub. I found the primer to need further cure. So with a full kit of epoxy already mixed, the applicator turned to me with a cheeky grin and said, "It will be alright if I just blow this kit out though?" He didn't want to waste the kit and instead wanted to use it by spraying it over the uncured IOZ. My response was simply, "I can't stop you from applying that kit, but it will be recorded in my report as a non-con- formance, and the client will need to provide approval." It seems that he must have thought about the barrage of emails and explanations required because he decided to sacrifice the mixed kit. ere are many standards and test methods we are asked to use that don't always ensure good workmanship, and it takes a keen inspector to identify areas of potential for poor quality outcomes. I had another project where I was the client's only representative. e applicator was asked to verify surface cleanliness in accordance with ISO 8502-3: Preparation of steel substrates before application of paints and related products — Tests for the assessment of surface cleanliness — Part 3: Assessment of dust on steel surfaces prepared for painting (pressure-sensitive tape method). e test is to be completed every 50 m² (538.2 sq. ft.), therefore the applicator supplied four tape samples for a 2,000 m² (21,527.8 sq. ft.) tank floor. W hen I performed my inspection, I found a fine powdery layer of spent garnet over a dark-colored holding primer that was not visible to the eye and could be viewed only when blowing the surface Photos courtesy of Justin Rigby Visit us at SSPC 2018 Conference Booth # 219 www.ecobondlbp.com 888-520-7132 info@ecobondlbp.com Lowers lead paint mitigation costs Reduces lead hazards up to 99% Eliminates up to 95% lead dust generation Treats in place; supports lead paint removal Re ad e r In qui r y at co ati n g sp ro m a g.co m /i n q0118
