This inspection survey must be conducted by qualified QA/QC personnel with knowledge of the fireproofing system, and recommended and approved by Isolatek International. As a result, any damage to the fire protection system can be easily repaired in accordance with Isolatek International’s application instructions.Īn annual inspection program is recommended to ensure that the integrity of a completely installed fireproofing system is maintained. Tunnel walls may be subjected to vehicle impact. Routine annual inspections may be carried out on the Spray-Applied Fire Resistive Materials (SFRMs) to ensure that the product will continue to perform its intended function. Inspection and Repair Procedures of the CAFCO ® FENDOLITE ® M-II / ISOLATEK ® Type M-II and CAFCO FENDOLITE TG / ISOLATEK Type TG System for Tunnel Applications – Short Form Refer to our Application Techniques section for more details regarding the step by step processes used. plastic coated galvanized or stainless steel profile mesh) may then be installed prior to the application of CAFCO FENDOLITE M-II / ISOLATEK Type M-II.įor applications onto metal lath substrates, concrete surface cleaning and the application of an SBR keycoat is not normally required. The specified method of mesh retention (i.e. For heavily contaminated substrates, this may be accomplished by pressure washing the entire concrete surface with a minimum 3000 psi pressure washer.įor direct application to concrete surfaces, a CAFCO FENDOLITE M-II / ISOLATEK Type M-II / ISOLATEK SBR keycoat is applied to increase the surface area to be protected by CAFCO FENDOLITE M-II / ISOLATEK Type M-II.

The substrate to be protected with the CAFCO ® FENDOLITE ® M-II / ISOLATEK ® Type M-II system must be prepared such that it is free from dirt, dust, oil, curing compounds, mold release agents or other contamination that would impair the adhesion of CAFCO FENDOLITE M-II / ISOLATEK Type M-II system. It is required that the substrates are prepared in accordance with Isolatek International’s written application instructions. Poorly prepared substrates will compromise the long term protection to the structure. diameter (13 mm).ĬAFCO FENDOLITE TG / ISOLATEK Type TG is mixed and then hand applied using common masonry tools.Ĭareful preparation of substrates is important. Correct preparation ensures that the durability of the fire protection system is maintained and the required level of adhesion is achieved.
