Pecora Dynatred is a multi-component, non-sag, traffic grade polyurethane sealant that has a designed Shore A Hardness of 40+. Because of this medium firmness and abrasion resistance, it is excellent for sealing joints in treads and risers, V-joints, control and expansion joints in parking decks and ramps, walkways, stadiums, industrial warehouse floors and other areas subject to pedestrian and vehicular traffic.1.5 gal pail.

Pecora Dynatred is a two-part, chemically-curing, cold-applied elastomeric sealant with the effectiveness of self leveling, traffic-grade sealants and the versatility of a non-sag material.
Once full cure has been established (7 days), Dynatred® has exceptional resistance to water submersion. Its wide color range makes it an ideal sealant for decorative flooring, patios and pedestrian malls as well.
For heavy pedestrian traffic areas subject to high heal exposure where joints exceed 3/8” in width, use Pecora Dynaflex.
Fire Rated Systems: Two-hour Underwriters Laboratories Classified fire-rated wall & floor joint systems up to 2” (50 mm) in width, Designs
(WWS 0021), (FFS 0017) can be designed with Ultra Block fire-blocking material. Ref: Standard Fire Tests of Building Const. & Materials,ANSI/UL 263,ASTM E119, NFPA No. 251,Vol. 2,
Surface Preparation: Surfaces must be clean and dry.The presence of moisture may cause gassing before the sealant achieves ultimate cure. Oil, grease, wax, form-release agents, curing compounds, bitumens, laitance and old caulking materials must be removed by sandblasting or sawing to sound, virgin substrates for optimum sealant performance.
Priming: All joints must be primed before applying Dynatred®. Pecora P-75 or P-150 primer is recommended on masonry and P-120 on aluminum, steel and galvanized metal. Primer must be dry before the application of Dynatred . Primers should not be allowed to dry over eight (8) hours.
Tooling: Tool immediately too assure full adhesion to the joint surfaces.Tooling without a slicking agent is preferred but if conditions require one, mineral spirits is recommended. (See Caution statement.)
Clean Up: Mechanically remove excess sealant. Wipe up residues with a small amount of mineral spirits on a rag following appropriate safety precautions on the supplier’s SDS or allow residues to cure and remove mechanically to decontaminate the area thoroughly
