Soudal Fix ALL Crystal Clear (290ml) – 100% Transparent Hybrid Polymer Adhesive & Sealant

Soudal Fix ALL Crystal Clear (290ml) is a fully transparent hybrid polymer
adhesive and sealant designed for invisible bonding and sealing on almost all
building materials. It combines high‑strength grab with long‑term flexibility in a
crystal clear, solvent‑free formula, ideal for interior and exterior applications
where a discreet finish is essential.

Soudal Fix ALL Crystal Clear (290ml) is a one‑component, moisture‑curing
hybrid polymer (SMX) adhesive sealant that cures to form a clear, elastic rubber
with excellent adhesion to a wide range of porous and non‑porous substrates. It
offers the strength of a construction adhesive combined with the movement
capability of a high‑quality sealant.

Unlike many “clear” products that dry cloudy, Fix ALL Crystal Clear is formulated
to be truly transparent, making it ideal for applications where the joint or
fixing should be as discreet and unobtrusive as possible – such as glass‑to‑glass
joints, transparent panels, decorative trims and display work. Its solvent‑free,
low‑odour composition makes it suitable for use in homes, offices, retail and
commercial environments as well as on construction sites.

Typical Use Cases

• Glass and transparent panel bonding – discreet bonding of glass shelves, acrylic panels, polycarbonate sheets and display cases.
• Sealing around glass and clear plastics – crystal clear perimeter seals around shower screens, glass partitions and glazed doors (check sanitary suitability).
• Decorative and interior fit‑out – invisible fixing of skirting, trims, beads, coving, LED profiles and stair nosings to most common substrates.
• Kitchen, bathroom and wet area sealing – clear sealing between worktops, splashbacks, tiles and sanitaryware where a coloured joint is undesirable.
• General construction bonding – multi‑material bonding for metal, wood, masonry, ceramics, PVC and composites in interior and exterior projects.

Usage & Application Tips

• Surface preparation:
  • Substrates must be clean, sound and free from dust, grease, oil, loose particles and release agents.
  • Degrease smooth surfaces (e.g. glass, metals, plastics) with a suitable cleaner.
  • Remove old, failing sealant or adhesive mechanically and/or with appropriate removers.
• Priming:
  • Fix ALL Crystal Clear generally adheres without primer to most common building materials.
  • On very porous or critical substrates (e.g. friable plaster, dusty brick), use a suitable primer or consolidating sealer as advised in Soudal documentation.
• Application as an adhesive:
  • Cut the cartridge tip, attach the nozzle and trim to the desired bead size.
  • Apply vertical beads or dots at regular centres (e.g. 10–20 cm) to one of the bonding surfaces.
  • For heavy items, use a combination of adhesive beads and temporary mechanical supports until cured.
  • Bring surfaces together within the open time, press firmly and adjust to final position.
• Application as a sealant:
  • Ensure joints are correctly dimensioned and, where necessary, use backing rod or bond‑breaker tape to achieve the proper joint profile.
  • Gun a continuous bead, ensuring full contact with joint sides and avoiding air pockets.
  • Tool the bead with a wetted spatula within the skin time to create a smooth, concave, well‑compacted joint.
• Curing & cleaning:
  • Fix ALL Crystal Clear cures by reaction with moisture; cure rate is typically around 2–3 mm per 24 hours, depending on joint size and conditions (see datasheet).
  • Remove uncured material from tools and surfaces with a suitable Soudal cleaner or white spirit.
  • Cured product can only be removed mechanically (cutting/scraping).
• Important notes:
  • Avoid using Fix ALL Crystal Clear where the adhesive/sealant will be under permanent water immersion unless confirmed suitable by Soudal for that system.
  • Not recommended for aquariums, natural stone prone to staining (e.g. some marbles) or for PE, PP, PTFE without priming/testing.
  • Prolonged UV exposure through thick beads may cause slight yellowing over time; for fully exposed façade joints, consider a coloured Fix ALL grade.

Frequently Asked Questions – Soudal Fix ALL Crystal Clear (290ml)

1. How clear is Soudal Fix ALL Crystal Clear compared to ordinary “clear” sealants?

Many conventional “clear” sealants dry to a milky or translucent finish.
Soudal Fix ALL Crystal Clear is engineered to cure to a genuinely transparent,
crystal clear joint when applied at normal bead thicknesses. This makes it far
better suited to glass‑to‑glass, glass‑to‑metal and decorative transparent joints
where visual appearance is critical.

2. Can Fix ALL Crystal Clear be used in bathrooms and showers?

Yes, Fix ALL Crystal Clear is water‑resistant and flexible, and can be used for
many bathroom and shower sealing and bonding tasks, such as around shower
screens, baths, basins and splashbacks. However:

• For continuously wet, high‑humidity areas, a dedicated sanitary/mould‑resistant grade from the Fix ALL or Soudal sanitary range may offer enhanced fungal resistance.
• Always ensure good surface preparation, joint design and ventilation for best long‑term performance.

3. Is Fix ALL Crystal Clear suitable for structural or load‑bearing applications?

Fix ALL Crystal Clear is a high‑strength construction adhesive but is generally
intended for non‑structural bonding and sealing. For heavily loaded or
structural applications:

• Follow the guidance of a structural engineer or system designer.
• Use mechanical fixings (screws, bolts, anchors) where Building Regulations require.
• Treat the adhesive as an auxiliary bonding aid unless specific test data and approvals permit structural use.

4. Can I paint over Soudal Fix ALL Crystal Clear?

Hybrid polymers like Fix ALL Crystal Clear are often paintable with water‑based
(acrylic) paints, but because the product is transparent, it is usually left
unpainted so that the clear aesthetic is preserved. If you do wish to paint:

• Allow the product to fully cure first.
• Carry out a small compatibility test, as some paints may dry more slowly or show slight changes in sheen over the joint.

5. Will Fix ALL Crystal Clear adhere to plastics like acrylic, polycarbonate and uPVC?

In many cases yes – Fix ALL Crystal Clear has excellent adhesion to many rigid
plastics such as uPVC, acrylic and polycarbonate. However, plastic formulations
vary, so it is important to:

• Degrease and lightly abrade smooth plastic where appropriate for better keyed adhesion.
• Test a small area first, especially on stress‑sensitive plastics to ensure no stress‑cracking or surface attack occurs.
• Avoid use on polyethylene (PE), polypropylene (PP) and PTFE without special priming and confirmation of suitability.

6. Common Uses & How to Use Soudal Fix ALL Crystal Clear (290ml)

Common Uses:

• Invisible bonding of glass shelves, decorative panels and acrylic displays.
• Clear sealing around glass shower screens, splashbacks and worktops.
• Fixing LED channels, trims, beads and profiles where visible adhesive would spoil the look.
• Multi‑material bonding in kitchens, bathrooms and shopfitting.
• General construction and maintenance bonding where a crystal clear joint is preferred.

How to Use – Step‑by‑Step:

1. Check substrates for compatibility; clean thoroughly to remove dust, grease and old residues.
2. Cut the cartridge tip, screw on the nozzle and cut the nozzle at an angle to suit the joint size.
3. Insert the 290 ml cartridge into a quality sealant/adhesive gun.
4. For bonding: apply beads or dots to one surface; for sealing: apply a continuous bead into the joint.
5. Bring surfaces together within the open time; press firmly and adjust into final position.
6. Tool the bead (for sealing applications) with a wetted spatula to create a smooth, concave profile.
7. Support heavy items mechanically or with props until sufficient cure has been achieved.
8. Allow the product to cure fully before subjecting to water immersion, heavy loads or cleaning.
