• Can Flex-Tec HV be sanded?
  Flex-Tec HV sands like a hardwood, the density of an oak or maple. It can also be chiseled, drilled, carved, or planed, just like wood.
  When working with concrete or masonry keep in mind that Flex-Tec HV can be molded and sculpted with ease. Our repair material will not slump or sag. A dremel tool can be used for fine detail work.
  
  
• Can Flex-Tec HV be stained?
  Since epoxy is not a porous material, it will not take stain like wood. You can, however, color the epoxy during the mixing process to give full depth of color to the material. Just add ART Epoxy tint to material while mixing.
  
  
• Can Flex-Tec HV be painted/ varnished?
  Yes, you must sand the surface first. After sanding an oil or latex paint/varnish system can be used.
  
  
• Why do you advocate removing all the decayed wood to sound, bright wood?
  Impregnating dirty, wet, contaminated wood fiber with a low viscosity “consolidant” will not provide a high quality bond to sound wood fibers. As the wood expands and contracts a poor bond will fail. This failure leads to further moisture penetration and wood decay.
  
  
• How do your materials compare to other repair materials?
  In two distinct ways:
  
  1- As noted above, ART is not a consolidation method of repair. Most other repair materials do not properly address the bonding failures found by poor adhesion to a poorly prepared subsurface.
  
  2 - ART’s products are specially engineered to work with the wood. High bonding strength (adhesion) together with a high degree of flexural strength (cohesion) allow for expansion and contraction of the wood with out adhesion or cohesion failure.
  
  
• Is your system structural?
  In compression load, yes. (ie: column bases, bottom of wood posts, etc.) In shear load (ie: floor joist, roof rafter, etc.), we recommend the use of fiberglass rod or rebar for strength. Consult an engineer for specific product applications.
  
  
• How much epoxy do I need for my repair project?
  It depends on the size of the repair. Flex-Tec HV is sold in a 450 ml/16 oz. dual-tube dispensing system. This amount is equal to the size of a grapefruit in volume. Prime-A-Trate cell-bonding primer is sold in a 350 ml/12 oz. container. Roughly, you will go through 4 or 5 sets of Flex-Tec HV to every set of Prime-A-Trate.
  
  
• How large of a repair can be done?
  Any size. Flex-Tec HV will not slump or sag in any volume. Flex-Tec HV will not shrink.
  
  
• Can Flex-Tec HV be left unpainted?
  Flex-Tec HV is engineered to withstand ultra-violet light degradation. All materials, however, deteriorate to some degree when left exposed to the elements. In instances where Flex-Tec HV is bonded to wood, we strongly recommend painting the entire surface to protect the wood and surrounding repair against Ultra Violet light and moisture degradation.
  
  
• What is the curing time?
  Prime-A-Trate has an open time of 2 to 3 hours. Flex-Tec HV has an open time of 30 to 45 minutes. Flex-Tec HV is designed to cure in 16 hours (overnight).
  
  
• What is the shelf life?
  Prime-A-Trate and Flex-Tec HV both have the same shelf life. Once opened, we recommend using the product within 1 year. Unopened, both products have a 2 year shelf life.
  
  
• What about safety?
  Prime-A-Trate and Flex-Tec HV contain no VOC’s. Like all epoxy compounds, care needs to be taken to protect exposure to skin and inhalation. Work in a well ventilated area, wear protective gear such as gloves and eye wear. Use a respirator if working in an unventilated area. See our MSDS for detailed safety issues.Flex-Tec part A | Flex-Tec par t B| Prime-A-Trate part A | Prime-A Trate Part B
  
  
• What is the difference between the Dispensing Gun and Static Mixing Gun?
  Both types of guns are good quality professional grade tools.
  
  The only major difference is the Static guns will enable the user to attach mixing nozzles to the tubes of Flex-Tec HV.
  The mixing nozzles require a higher pressure to push and mix the material as it is dispensed.
  
  The Dispensing Guns are only designed for dispensing and manual mixing.
  
  ART 300LV Dual Cartridge Dispensing Gun Requires Manual Mixing DO NOT USE Static Mixing Nozzles with this gun. The ART 300 LV Dual Cartridge Dispensing Gun is not engineered to withstand the extra force required to push the epoxy through the nozzles.
  
  ART CR200 Single Cartridge Manual Mixing Gun Requires Manual Mixing
  For your smaller volume epoxy repairs – Use with 150ml cartridge which has two internal chambers to separate the two-part epoxy. No thumb release, no buttons to push, no special way to click the handle. It’s simple and automatic.
  DO NOT USE Static Mixing Nozzles with this gun. The ART CR200 Single Cartridge Dispensing Gun is not engineered to withstand the extra force required to push the epoxy through the nozzles.
  
  ART 300X Dual Cartridge Static Mixing Gun Offers Optional Use of Static Mixing Nozzles
  Cut down considerably on yourwork-time with this gun. It is designed be used with ART’s 450ml dual cartridge and ART’s Static Mixing Nozzles
  
  ART 41004-XT Static Mixing GunOffers Option To Use StaticMixing Nozzles
  This gun gives you the convenienceof the smaller 150ml tube with the capability to use ART’s static mixing nozzles.
  Note: the 150ml cartridge has two internal chambers which separate the two-part epoxy.
  When used with static mixing nozzles, the two-part epoxy is mixed as it is pushed through the nozzle. No manual mixing required!
