Wet Spray



Support - Protective Coatings Industry

Our Wet Mix SFRM product line is available in Commercial, Medium, and High Density versions, all with unique properties and benefits.

The application of the ISOLATEK® Type 300 family of products, ISOLATEK® Type 400 and ISOLATEK® Type M-II consists of mixing the product with potable water in a paddle or ribbon type mixer. The mixed product is then placed into a pump hopper where it is conveyed through a hose to a spray nozzle. As the mixed product exits the spray nozzle, it is broken up into a fan pattern by compressed air and directed at the surface to be covered in an even, uninterrupted pattern. These products have also been known in the industry as “cementitious” materials, due to their application techniques being similar to that of cement and other plastering trade products.

Products



In order to obtain optimal results, the following spray equipment setup for “Wet Spray” ISOLATEK® Spray-Applied Fire Resistive Materials (SFRMs) is required:

  • The spray equipment may consist of Mechanical Piston, Hydraulic Piston or Rotor Stator type, open throat, screw feed pumps with minimum “No. 4” soft rubber stators. The actual equipment type is dependent upon the actual product being installed.
  • Compressed air is required and must be delivered to the spray nozzle. At times, an auxiliary compressor may be needed.
  • Paddle or ribbon-type mortar mixer with safety cover and provision for quick dumping of mix directly into the pump hopper. Mixers capable of operating speeds of 35 to 40 RPM.
  • High pressure plaster type hose. Hose diameters and lengths vary, depending on the product being sprayed and pump being used.
  • Screw-on type quick connect/disconnect couplings that do not restrict product flow are required.
  • The spray nozzle assembly with a blow-off type nozzle cap, a nozzle orifice and valves for product and air control. Nozzle orifice must be nominal 13mm. (1/2 in) to 16mm. (5/8 in) diameter, depending on product being applied.

Acceptable substrates for sprayed fire resistive materials are structural steel, steel deck and concrete. Careful preparation of these substrates is important. This preparation ensures that the durability of the fire protection system is maintained and the required level of adhesion is achieved.

All substrates to be protected with the fire protection system must be prepared such that they are free from dirt, dust, oil, incompatible primers or other contamination that would impair the adhesion. The recommended substrate for optimal adhesion is clean bare steel and galvanised decking. However, at times primed steel is necessary, especially in areas where long term corrosion protection is necessary. The following items briefly outline additional recommended steel substrate preparation for steelwork, decking and concrete.

Steelwork

For interior application, ISOLATEK® fire protection materials can be installed directly to clean bare steel substrates without the use of additional reinforcement.

For certain applications, specifically on coated steel substrates, mechanical reinforcement is necessary. This is done by means of galvanised metal lath or galvanised or plastic coated galvanised woven wire or hexagonal mesh.

Galvanised metal lath is secured to the substrate in either a strip, contour or boxed configuration in accordance with Isolatek’s application Instructions and design guidelines. For applications where galvanised or plastic coated mesh is used, the mesh is secured to the steel by use of stud welded, helical or powder actuated fasteners. The reinforcing mesh is held to the substrate at the fixing points, and then pulled away from the substrate to the middle third of the total thickness of the product as it is being applied.

For painted / primed steel applications, a specific level of adhesion must be maintained to the steel substrate in accordance with manufacturer, industry or laboratory guidelines. Many times in order to achieve this adhesion to the substrate, a primer / sealer / key coat, adhesive and/or mechanical reinforcement are necessary.

Specific guides are necessary, when applying fireproofing materials in accordance with the guidelines set-forth by Underwriters Laboratories (UL). An explanation of these guidelines can be found within Isolutions Number 5.

Decking

Proper adhesion of product depends upon rigid substrates and the absence of damaging forces such as impact or excessive forces.

It is important to make certain that roof traffic, incomplete roof work, deck spans with deflections greater than L/240 when subjected to a 113 kg (250 lb.) vertical center load do not exist before applying product.

ISOLATEK fireproofing products require the use of ISOLATEK® Type EBS adhesive installed to the underside of all roof deck (without concrete) and painted/primed floor deck, directly prior to the application of the fireproofing material to the underside of the decking.

For painted / primed decking, a specific level of adhesion must be maintained to the steel substrate in accordance with manufacturer, industry or laboratory guidelines. In addition, testing laboratory specific guidelines must be met. For certain applications, complete coverage of metal lath reinforcement may be necessary.

Specific procedure must be followed when applying fireproofing materials in accordance with the guidelines set-forth by Underwriters Laboratories (UL). An explanation of these guidelines can be found within Isolutions Number 6.

Concrete

Residual form oils, and parting compounds or paint/primers must be removed with a suitable commercial cleaning compound. Contact the substrate manufacturer or supplier for cleaning recommendations. Depending upon the fireproofing material being used, either ISOLATEK Type EBS adhesive, ISOLATEK® Type PC or metal lath is required prior to the application of product.

”A Maintenance program is essential to maintain the
integrity of a completely
installed fireproofing system.”

Maintenance of Spray-Applied Fire Resistive Materials

Routine maintenance performed through testing and inspection of Spray-Applied Fireproofing, also known as Spray-Applied Fire Resistive Materials (SFRMs), ensures that the product will be in-place for the design life of the structure and perform in actual building fire conditions.

Commercial structures undergo renovations and upgrades related to tenant change and use & occupancy change. As a result, partitions and walls
may be removed, electrical wiring redirected, mechanical equipment removed/replaced, and roof systems changed. When these conditions exist, any
SFRM is susceptible to damage caused by impact and this can result in SFRM delamination. Structural steel beams, joists, columns and decking may
then be vulnerable to the damaging effects of fire.

The procedures outlined below are intended as a guide for inspection testing of SFRMs while conducting your periodic maintenance program.

  1. Identify all areas throughout the structure that have undergone a renovation or upgrade since the previous inspection. In addition, identify all areas that are susceptible to periodic or regular maintenance traffic and periodic or regular public traffic.
  2. Visually inspect the aforementioned areas and note all SFRM deficiencies such as material that has been removed or damaged.
  3. Inspect surrounding SFRM near the damaged areas to ensure the required thicknesses and cohesion/adhesion characteristics are maintained.
  4. Identify the type of SFRM utilized to protect the structural steel framework; i.e. beams, joists, columns and decking. The type of SFRM can usually be determined by reviewing construction documents or
  5. contacting SFRM Manufacturers.
  6. Obtain instructions from the applicable SFRM Manufacturer detailing the repair procedures for the exact SFRM type that has been damaged.
  7. Secure a sufficient quantity of SFRM from the applicable Manufacturer or contact the Manufacturer for names of qualified installers of the SFRM type. Repair of the existing SFRM shall be performed in accordance with the Manufacturer’s published installation instructions.

INSPECTION

  • ASTM E605 – “Standard Test Methods for Thickness and Density of Sprayed Fire Resistive Material (SFRM) Applied to Structural Members”
  • ASTM E736 – “Standard Test Method for Cohesion/Adhesion of Sprayed Fire Resistive Material Applied to Structural Members”
  • AWCI – “Technical Manual 12-A Third Edition – Standard Practice for the Testing and Inspection of Field Applied Sprayed Fire-Resistive Materials; an Annotated Guide”

Isolatek International believes that Building Owners/Managers should develop and implement a comprehensive plan detailing a Periodic Inspection and Maintenance Program for SFRMs. Should you have further questions pertaining to this matter, please contact the Isolatek International Technical Service Department at +1 973.347.1200, extension 269.
