E5829V Vertical Expansion Joint Filler & Flexible Sealant

E5829V is a two component 100% solids flexible sealant paste designed for interior applications where a resilient flexible non-sag material is needed. The E5829V is an excellent choice for vertical interior expansion joint applications. This product has excellent flexibility and provides exceptional adhesion characteristics.

E5829V is a gray color after mixing with black and white components so proper mixing can be easily observed Recommended for expansion joints in vertical structures, vertical and overhead repairs and any other non-sag vertical application repairs of joints or cracks in concrete or masonry surfaces.   Not recommended for applications for all acids and chemicals.

Available in 2 gallon and 10 gallon kits.

PRIMER: None required
TOPCOAT: None required. Many acrylic, epoxy and urethane coatings are compatible.

1) PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using.  Continuous storage should be between 50-90°F.  Avoid low temperatures and large temperature fluctuations in storage as these conditions could cause possible product crystallization. 2) SURFACE PREPARATION: All dirt, oil, dust, foreign contaminants, and laitance must be removed to assure a trouble free bond to the substrate.  We recommend that all loose concrete, previous patching compound or other foreign material be removed to leave a clean sound joint or repair area.  For best results, when the depth of the repair area permits, a backer rod should be used to reduce the depth of the repair area.  If the repair is too deep to prevent sag or slump, apply the material in multiple coats.  For vertical surfaces, a lower viscosity version of this product is available. 3) PRIMER:  No primer is necessary.  This material is self-priming.  However, any suitable primer can be used. 4) PRODUCT MIXING: It is important that the material be mixed well.  Therefore take a few extra minutes to make sure adequate time has been taken to mix the two components together thoroughly.  Improper mixing will cause an incomplete cure and soft spots in the repair area or joint.  Mix one part (by volume) part A to one part (by volume) part B in an oversized mixing container.  Mix well with slow speed mixing equipment until totally streak free being sure to scrape the sides and bottom of the mixing container thoroughly.  Avoid high speed mixing as this could force air into the product. 5) PRODUCT APPLICATION: Apply the mixed product by placing the material into the repair area or joint with a marginal trowel, putty knife or other suitable equipment.  Remove any excess material with a putty knife or similar tool prior to curing.  Alternatively, it may also be suitable to let the product become tack free in the joint and then using a razor scraper to cut off or shave the excess above the surface plane. Maintain temperatures within the recommended ranges during the application and  curing process.  When temperatures are lower, allow more time for this material to cure. 6) RECOAT OR TOPCOATING:  No recoating or topcoating is necessary.  However, if you opt to topcoat the applied joint compound, allow it to cure before topcoating.  It is not necessary to prime over the joint compound prior to topcoating the joint compound.  Many acrylic, epoxies and urethanes can be used.  In some instances, especially when excessive expansion joint movement is involved, topcoats may chip.  However, most epoxy or topcoat products will adhere to the joint compound very well. 7) CLEANUP: Use xylol. 8) SURFACE CLEANING: Caution!  Some cleaners may affect the color of the floor installed Test each cleaner in a small area, utilizing your cleaning technique.  If no ill effects are noted, you can continue to clean with the product and process tested. 9) RESTRICTIONS: Restrict the use of the area to light duty use and non-harsh chemicals until the coating is fully cured (see technical data under full cure).  It is best to let the repair area remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.
