Product description
Wiseal NF is a multi-purpose nail-free adhesive with strong bonding strength. It can replace nails when fixing materials without drilling into the surface. Suitable for wood, gypsum board, medium-density fibreboard, stone, cement, porcelain, metal, plastic and rubber.
Packaging: 300 ml per cartridge, 24 cartridges per box.
Product features
- Strong adhesion and high bonding strength
- Flexible bond that accommodates building movement without becoming brittle
- Bonds a wide range of substrates, including wet wood
- Does not sag; can be filled and painted after drying
- Weather-resistant and waterproof
Applications
- Fixing hooks, skirtings, wall panels and decorative boards without nails
- Bonding wood, gypsum board, MDF, stone, cement, porcelain, metal, plastic and rubber
Directions for use
Clean the bonding surfaces so they are free of oil and dirt. Cut open the cartridge, fit the nozzle and apply with a caulking gun.
Dry bonding for lighter materials: apply adhesive in zigzag beads, press the parts together, then pull them apart briefly to let the adhesive evaporate for a few minutes before pressing them firmly together again.
Wet bonding for heavier materials: apply the adhesive, join the parts and secure them with clamps, nails or screws for about 24 hours while it cures.
Adjust the position within 20 minutes. The bond becomes more stable after 2–3 days and reaches its best effect after 7 days.

Cautions
- Remove uncured excess adhesive before it sets; scrape or sand off residue after drying.
- Bond strength can decrease at high temperatures, especially on metal exposed to prolonged sunlight.
- Avoid prolonged skin contact. Use in a well-ventilated area away from heat and sources of fire.
- Store in a cool, dry place. Keep adhesive out of water sources; let leftovers dry completely before disposal.
