Product Description

The SGM Dynamite Pool Patch is a high-strength, polymer-modified pressure waterproof mortar designed specifically for underwater or dry repairs of pool finishes. This fast-setting formula allows you to patch cracks, chips, and hollow spots in plaster, Marcite, or Pebble finishes without the need to drain the entire pool.

Key Product Features

  • Underwater Application: Specially engineered to be applied and cured while submerged, saving thousands of gallons of water and chemical balancing time.
  • High Bond Strength: Features a polymer-modified blend that creates a superior chemical and mechanical bond to existing pool shells.
  • Fast Setting: Rapid-cure technology allows the patch to harden quickly, preventing "wash-out" from pool circulation pumps or bather activity.
  • Versatile Surface Prep: Ideal for filling "pop-outs," repairing delaminated areas, and sealing structural cracks in both residential and commercial pools

⚠️ Critical Safety & Application Warnings

EYE & SKIN IRRITANT: Contains Portland Cement and Silica. Wear waterproof gloves and eye protection during mixing. Avoid breathing dust.
COLOR MATCHING: Aged plaster often shifts color. Perform a test patch first; White is standard but can be tinted with SGM color packs.
STRUCTURAL MOVEMENT: This patch is for static repairs only. It will not stop leaks caused by active structural shifting or pool shell settling.
💡 Professional Installation Tips
  • Surface Prep: Use a chisel to remove "drummy" or loose plaster. A clean, solid substrate is vital for a permanent bond.
  • The "Dive" Method: Carry the patch ball to the site inside a small plastic bag to prevent "trailing" (clouding the water) during the swim down.
  • No Mechanical Mixing: Hand-mix small batches with a margin trowel to avoid whipping excess air into the mortar.
  • Avoid Over-Smoothing: Stroke only a few times. Excess troweling underwater causes cement paste to float away, leaving a weak, sandy finish.
PROCEED WITH CAUTION: Chemical products like pool mortar require careful handling. Always follow local safety regulations and wear appropriate Personal Protective Equipment (PPE).
