Parking, Pedestrian, & Bridge Deck Broadcasting
Reevaluating old assumptions about the term
"Broadcast to Rejection"
Why Do This & Have Tons of Sweep, Mounding, & An Uneven Surface With Holidays That When Topcoated, Will NOT Look Very Nice In The Eyes of The Owner.
WHO NEEDS THAT AGGRAVATION???
When You Can Do This (below) And Have Little to No Sweep and a Nice Even Surface!
(the contractor above now uses our machines)
(watch the short video below and notice how the operator selectively takes out a shot blast line that was deeper and consumed more sand after the initial blow)
(watch a longer version on https://www.facebook.com/BroadcastingPro "Pretty simple stuff, etc" at the post entered on Feb 1)
"...it's not only fast, but I like how much better the deck looks when we're done"
Jeffrey Kindschuh, CRX, Houston TX.
In the above picture, silica sand was finessed onto the wet surface and then the silica sand was backrolled in while the elastomeric coating was still wet. Not much fun doing it by hand!!!
That's the type of control you have with the BroadcastPro6 machine.
Here is an operator finnesing in the perimeter sand by turning down the RPM's (Throttle Control) and adjusting/closing partially the rate of flow of the sand with the flow control valve/handle next to the Throttle Handle pictured to the right of his arm.
Another way to handle this situation is blow off the adjacent floor, not to be coated, with the blower to remove any debris, broadcast the floor as usual and simply blow any adjacent excess back on to the coated floor. Some operators will leave the edges a little 'bald' to accommodate the overspray when it's pushed/blown back on the coating to clean up the excess sand in surrounding areas. .
EITHER WAY,,, SIMPLE.
The contractor pictured above has multiple machine's as most deck contractors do. On large, wide open projects, he combines the machines for superior speed and performance over any other method available, (and we've tried them all), with pinpoint accuracy.
No cumbersome hoses or cords to contend with. The operator is out of the way of the coating crew. Just a simple, common sense approach to the age old problems associated with hand broadcasting.
Occasionally, 'doubter' contractors looking at the system will say, "we need to broadcast more sand and it would be too much loading".
Nothing could be further from reality!
That assumption from the 'doubter' is based on the 'broadcasting by hand' way of thinking. Having not been exposed to the advantages of mechanical broadcasting and all the benefits they are unaware of, will 'shoot down' that assumption.
First, the hopper/holding tank is strategically designed to hold a 50 pound bag of sand or aggregate, or for decorative flooring contractor a bag of colored quartz, or a 55 pound box of flake, and for the roofing industry a 50 pound bag of granules or a 50 pound bag of aluminum flake, eliminating partial bags laying around. The bag is simply placed on the top of the hopper, slit with a knife or ripped by hand, and the contents empty into the hopper, put the lid on the hopper and resume broadcasting. Or in some instances, never stop broadcasting while the hopper is being loaded. There are several methods employed to load the hopper on the fly. See the video on the Home Page for one example towards the end of the video. Simply call for more ways to broadcast and fill 'on the fly'. Portable bulk loading systems are available. Call or email for details.
Second, reports from the field (see Testimonials) attest to an ~50% savings in consumption of broadcast media. In addition, many report mastering 'no sweep' broadcasting. If the consumption is ~50% less, and, you don't have the labor associated with that bag of sand, not only the broadcasting portion, there is also labor associated with the 'sweep up' of the excess sand in that bag.
Based on these scenarios, one bag will cover twice the square footage compared to broadcasting by hand, making it quicker and cheaper. When looked at from this perspective, and considering reports from the field, using the broadcast machine is actually quicker and saves a lot of money on that phase of the operation.
With two machines, it's easy to keep up with a 125'+ foot wide pour line with fast (20-30 minute) cure material. If you would like to see the video, I would be glad to send the file.
Some roofing, waterproofing, and flooring contractors have up to eight machines and tackle very large roofs, park decks, and floors.
To those contractors/applicators, it's a 'don't leave home without it' type of tool for the job site, no matter the size.
Obviously they see the benefits
HOW ABOUT YOU?
The video and the pictures say it all.
Wouldn't you agree?
The contractor in the first picture at the very top of the page switched from hand broadcasting, and now uses the BroadcastPro6.
You should consider switching also to save ~50% on media consumption and ~50% on labor to apply and cleanup!
ROI (return on investment) is immediate on most projects depending on size, see Testimonials
In the case of the first picture at the top of the page of hand broadcasting, recovery was in the tons! Think about the labor not only to clean it up, but then the labor associated with managing/logistics of all that excess media. In reality the labor number is much more than most would assume when you really 'drill down' and look at it objectively.
Applicators who have mastered the machine report LITTLE to NO sweep.
Some report (Testimonials) mastering 'no sweep' broadcasting on the first job!!!
