EB25 is perfect for sealing and bonding in almost any application imaginable. It excels as a high-quality nail replacement adhesive, even on damp surfaces, and is ideal for external and internal perimeter pointing around doors and windows. It can bond mirrors to most common substrates, seal vertical expansion joints, join cladding panels, and handle high-performance, durable joint sealing. Additionally, it’s suitable for applications requiring resistance to chemical spills.
APPLICATION
For nail replacement (panel) adhesive applications: Prime dusty surfaces with Everbuild 501 PVA Bond diluted 1:4 with water and allow to dry. Use a standard sealant gun to apply; cut the cartridge tip, fit the nozzle, and adjust the opening to the desired bead size. For heavy items like plasterboard or worktops, apply adhesive around the edge (30-50 mm from the perimeter) and in beads at 300 mm intervals, or directly on battens, pressing them into place. Temporary support is required for heavy items until the adhesive dries. For lightweight items like covings or skirting, apply continuous beads to the back and press into position immediately. If gap filling is needed, apply thicker beads in areas with large gaps. Clean excess adhesive immediately with a cloth or white spirits.
For sealant applications: EB25 is certified for EN15651 façade and sanitary use, suitable for interior, exterior, and cold climates. Follow recommended joint ratios, reducing joint depth with Everbuild® Expanding Foam or Joint Backer Rod as needed. Ensure adhesion to only two surfaces to maintain flexibility. Use masking tape to prevent contamination of adjacent surfaces and remove it immediately after tooling, which should occur within 5 minutes for a smooth finish.
For fixing mirrors: Apply 6 mm diameter beads of sealant to the back of the mirror in vertical strips, spaced 30-40 mm apart. Press the mirror into place with even pressure and slight twisting, securing with temporary support for 24-48 hours. Once cured, seal around the mirror if needed. Remove uncured material with white spirit and cured material mechanically. Allow full curing before overpainting.
Cleaning of Tools:
Uncured product: Use Sika® Wonder Wipes or white spirit.
Cured product: Remove mechanically.
Limitations:
- Use mechanical fixings for overhead applications, glass blocks, or large mirrors (>0.5 m²).
- Temporary support is essential for heavy items until adhesive cures.
- UV exposure may cause slight discoloration without affecting performance.
- Do not seal mirror edges or plastic sheeting until the adhesive cures.
- Check paint compatibility before overpainting.
- Avoid use on surfaces that bleed oils or plasticizers.
- Not suitable for structural glazing, aquarium manufacture, chlorinated water, or in conjunction with bitumen or asphalt.
- Do not use with undiluted bleach to prevent discoloration.
- Yellowing may occur in dark conditions.
