Construction Method
Base Surface Treatment: Chisel out V-shaped groove along crack, remove loose material and clean with water, keep damp.
Mixing: Add powder to water, quickly stir 30–60 seconds to thick paste; mix only what can be used in 2 minutes.
Plugging:Press mixed material firmly into leak with gloved hand, hold for 1–3 minutes until set; for heavy flow, use cotton cloth wrapped material to plug first.
Finishing:After initial set, smooth surface and apply waterproof coating for long-term protection; cure with water for 24 hours.
