Painter’s Corner: MCAA Magazine

MCAA Magazine Jerry Painter   Question: How Close is Too Close? Have you ever had someone or something encroach on your personal space so badly that you wanted to scream “Back Off!”? So how close is too close? When my daughters were in high school, they went to a school that had a “Six Inch Rule”. Boys and girls had a 6” rule of separation. Now, as most of you fathers of daughters know, six inches is simply not enough! A distance that can be critical for a masonry contractor is the distance from which masonry should be viewed to determine its acceptability. If we have reached the point of trying to view the masonry from a certain distance, we already have a problem. ASTM C90 Section 7 is titled “Finish & Appearance of Concrete Masonry Units”. Paragraph 7.2 says and I quote, “Where units are to be used in exposed wall construction, the face or faces that are to be exposed shall not show chips or cracks, not otherwise permitted in 7.1.2 and 7.1.3, or other imperfections when viewed from a distance of not less than 20 ft. (6.1m)under diffused lighting”. So, there it is folks, the magic 20’-0” rule. We have been using it for years to get everyone to back away from the wall. But let me tell you a little secret, ASTM C90 is a...

Blast From The Past: Bill Dentinger

Publisher’s Note: One of my favorite features in Masonry has always been the Chairman’s Message. The sad thing is, readers hear from the MCAA Chairman for 24 issues of Masonry. Come the 25th issue, they are gone and for the most part not heard from again. In this new feature, we have asked our Past Chairmen to write a piece for us on what has happened since they were Chairman. It is a nice follow-up to what happened to them. This first run will feature Bill Dentinger, who served as MCAA President from 1984-1986. We hope you enjoy hearing...

Tech Talk: How To Look At A Brick Wall

On some projects it just seems that nobody can agree on wall appearance, and what looks right to one person can be unacceptable to another. There may be complaints about mortar color, joint width, or cracks and chips in the brick. Some architects like to get up close with a straightedge or a magnifying glass when evaluating a wall – but both of these approaches are wrong! Luckily there is guidance within the building code and ASTM on how to judge masonry wall appearance. Construction tolerances. Masonry design and construction is covered in the TMS 402 Building Code and...

A Bundle of Productivity: Grinders + Vacuums + Safety

  You make a mess ~ you clean it up. That’s a simple discipline that follows us throughout life, from the playroom, kitchen or classroom to the backyard, office, laboratory, workplace and construction job site. Grinding can be especially messy, and masonry grinders and vacuums go together like a ticker tape parade and a street sweeper. There are many instances of grinding that require great skill, human protection and the ubiquitous clean-up – like dental procedures, woodworking, metal grinding in a machine shop or auto body shop and masonry tasks. Varying levels of precision are involved, and there’s an...

MCAA Gateway: June 2017

Last chance to enter Safety Advantage Awards Submissions due June 30 Words: Zach Everett   Submissions to the MCAA Safety Advantage Awards, sponsored by Federated Insurance, are due by June 30, 2017. This is your last chance to enter the awards. Safety is overlooked by some contractors for several reasons: cost, time, resources, compounded focus on production, simple ignorance, or possibly many other things. Our goal is for the MCAA safety awards to help draw attention to the need and benefits of performing safely. The awards will be presented based on a company’s Incident Rate. This seemed to be the most equitable and best way to judge between contractors. The Incident Rate will be the only criteria at the present. There could be many other guidelines thrown into the mix; OSHA citations, comprehensiveness of safety policy, superseding of OSHA compliance by company policy, peer review of policies, job site inspections, volunteer safety work, using biodegradable earplugs, non-concrete block, utilizing anti-alien abduction hardhats or a gamut of other qualifiers and disqualifiers, but we thought that starting simple would be best for the moment. The Incident Rate, by which the safety awards will be judged, is calculated off of the OSHA logs. ALL OSHA recordable injuries and illnesses are logged for that year. The number of illnesses and injuries are multiplied by 200,000 then divided into the total number of hours...
