HOW DO I APPLY UFP?
Using UFP is as easy as 1, 2, 3! 1). Prepare substrate - Surface should be clean of any dirt, dust, oils or anything that might impede the UFP from attaching to the steel. In most cases, a simple wipe down with a coarse cloth should be sufficient to create the needed sound substrate. In extreme conditions, additional preparation may be necessary. 2). Mix UFP - Follow mixing instructions on the bucket. Put as much UFP as needed into a mixing tub. Add water using this ratio - approximately 1 lb. of UFP to 1 pint of potable water (we suggest holding back about 20% of the water), and only add remaining water if needed after mixing. Continue to mix until desired consistency - it should resemble a textured compound with a consistency of a thick oatmeal. A spray application may be slightly wetter. Consistency can be easily adjusted by either adding more water or more UFP. 3). Apply UFP - Once mixed, you will have several hours to apply UFP (i.e. "pot life"). We recommend * "patch to match"- apply UFP at the same thickness as the original material - with the assumption that the original materials have been applied correctly (*for the most thorough application, increase the depth of UFP beyond the required "patch to match" directive. The cost of the additional material is negligible, but the cost to come back to recoat is extraordinary. The idea is to apply it once, correctly, or even if a bit generous. and move on). A good rule of thumb is 3/4" to 1" per pass. At the point of contact (the perimeter of the patch), with the existing SFRM the UFP should be well troweled into the multiple cracks and crevices that may exist. A good transition between the new UFP and the existing SFRM is important as we really do not want to see any delamination (separation) between the two materials. Once the perimeter has been troweled, continue to fill the balance of the void left by the missing fireproofing. Of course, if you suspect the original application is too thick or thin, please ask us for assistance with determining the correct thickness for the patch to a specific member.Read More
WHAT TESTING HAS UFP GONE THROUGH?
Fireproofing is one of the most regulated trades on the construction site. I’m not sure exactly why but I think it has something to do with the fact that most fireproofing materials are literally manufactured on site and with that manufacturing there can be a lot of variables, product density, mix time and speed, amount of water added. All things that have an impact on the final in-place product – that has to work when needed at whatever timeline that might be. Another contributing factor, in my opinion is that not many truly understand fireproofing; the products, the applications, the purpose, how it works, etc.Read More
