Sealant-Applied vs. Self-Adhesive Membrane: How to Choose

Both types work. The right choice depends on wall condition, project type, and crew experience. Quick comparison: Sealant-Applied Self-Adhesive Tape Wall flatness Tolerates uneven surfaces Needs smooth walls Learning curve Easy, high fault tolerance Instant bond, low tolerance Speed Slower (2-step + cure time) Faster, peel & stick Winter use Limited by curing temp Works in cold weather Aesthetics Functional Cleaner finish Recommendations by wall type: ✅ Smooth walls (aluminum formwork concrete, precast panels) → Either works. Pick based on crew preference and budget. ⚠️ Rough walls (timber/bamboo formwork, ALC panels, honeycomb surfaces) → Sealant-applied is the safe choice. Or pre-plaster with crack-resistant mortar to create a flat surface, then switch to self-adhesive tape. ? Pitted window reveals → Same fix: pre-plaster first, then self-adhesive tape preferred. ? One more thing: Whatever you choose, make sure it complies with the project's applicable technical standard — national standard atlases, provincial standards (Hebei, Beijing, etc.). ?
