Euclid Speed Plug: 5 Gallon Hydraulic Cement

Euclid Speed Plug is a rapid-setting hydraulic type of cement compound used to instantly stop running water or seepage in masonry or concrete. Speed Plug is ready to use very similar to mortar, and requires only the addition of water before plugging and sealing active leaks. Speed Plug is available in a standard 1-3 minute set time formula,  and a slower setting 3-5 minute formulation. Questions about Euclid Speed Plug? Contact Us

Directions for Use:
Surface Preparation: Concrete surfaces must be structurally sound, and free of loose or deteriorated concrete and free of dust,  all other contaminants. Mechanically abrade the surface to achieve a surface profile equal to CSP >3 in accordance with ICRI Guideline 310.2. Properly clean profiled area.

Priming: Clean and prime exposed steel with DURALPREP A.C. and allow to fully dry prior to the application of speed plug hydraulic water stop cement.

Mixing: Pour potable water into a clean mixing container and gradually add the mix. Use approximately 1 quart of water to 8 to 9 lbs (3.8 to 4.3 kg/L) of material. Mix rapidly with a trowel to the consistency of stiff putty with no slump for no more than 30 seconds. Cement will flash set in 1 to 3 minutes. Properly mixed, the plug  can be hand formed into a ball.

Application: the material designed is for SSD areas for repair with potable submerged water immediately before application of speed plug cement mix. Used in applications to stop running water for immediate repair cement sets very quickly.

General Patching: Force speed plug into the crack or hole by hand or with a trowel before it sets and hardens. Rapidly fill to the full depth of the opening. Patching Active Leaks: Start at the top of the crack or hole, and force the high durability plug to the full depth of the prepared area. Apply direct pressure to the new patch until the speed plug has taken a firm set. Mix fresh material, and continue patching toward the area of the greatest pressure. When extreme water pressure is encountered, physically hold the mixed with a hand against the leak and apply continuous pressure until the speed plug has set, and the water has stopped running. Do not use a twisting motion.

Floor-Wall Patching: Follow above methods for leaks in concrete or masonry for the conditions encountered. Use a rounded tool to force the SPEED PLUG into the joint, and construct a 45 degree cove between the floor and wall at the same time. Expansion/Contraction Cracks: Do not use SPEED PLUG to treat dynamic cracks. Consult the technical data sheets for the DURAL AQUA LINE of chemical and urethane grouts do not use on frozen surfaces.
