FAQs
What types of surfaces can I use Sikaflex 522 on?
Sikaflex 522 is compatible with a wide range of materials including timber, glass, metals, metal primers and paint coatings, 2-part systems, ceramic materials, and various plastics. Always ensure surfaces are clean and dry before application.
Is Sikaflex 522 suitable for exterior applications on my caravan/motorhome?
Yes, it is highly resistant to weathering and aging, making it an excellent choice for exterior elastic sealing and bonding applications, such as around windows, roof vents, and body seams.
Can I use this sealant for interior repairs or installations?
Absolutely. Sikaflex 522 is suitable for interior elastic sealing and bonding, including areas of air ventilation and incidental food contact, thanks to its low emission profile and EHS compliance.
What does 'low emission' mean for this product?
Low emission means that Sikaflex 522 releases very few volatile organic compounds (VOCs) during and after application. This contributes to better indoor air quality and aligns with high Environmental, Health, and Safety (EHS) standards.
Do I need to prime the surfaces before applying Sikaflex 522?
Sikaflex 522 bonds well with minimal pretreatment. However, for critical applications or specific substrates, referring to the Sika technical data sheet for primer recommendations can ensure optimal adhesion and durability.
Is this sealant paintable?
> Info needed: Please consult the official Sika Sikaflex 522 technical data sheet for specific information regarding its paintability and recommended paint types.
How long does Sikaflex 522 take to fully cure?
> Info needed: The full cure time for Sikaflex 522 depends on environmental factors like temperature and humidity. Always refer to the product's technical data sheet for precise curing specifications.
Troubleshooting
Sealant does not adhere properly or peels off.
Ensure surfaces are thoroughly clean, dry, and free of grease, dust, or old sealant residue. Surface preparation is critical for good adhesion. Perform a small adhesion test on an inconspicuous area if unsure.
Sealant bead is inconsistent or messy.
Cut the nozzle at a 45-degree angle to the desired bead size. Apply with a steady, even pressure, maintaining a consistent speed. Practice on a scrap piece if needed. Use masking tape for clean edges and remove it immediately after application, before the sealant skins over.
Sealant appears soft or doesn't seem to be curing.
Verify that the ambient temperature and humidity are within the recommended range for the product's cure time (refer to technical data sheet). Ensure adequate ventilation for solvent-based products if applicable (though this is an STP, good air circulation helps). High humidity can sometimes speed up cure, but very low humidity can slow it down. Extremely cold temperatures will also significantly delay curing.
Bubbles or voids appear in the cured sealant.
This can happen if the sealant is applied too thickly in one pass, or if air is trapped during application. Apply in thinner, more consistent beads where possible. Avoid overworking the sealant after initial application. Ensure the substrate is not outgassing, especially porous materials.

Setup, Compatibility & Care Instructions
Setup
Before applying Sikaflex 522, ensure all surfaces are clean, dry, and free from dust, grease, oil, and any loose particles. While the product requires minimal pretreatment, a thorough surface wipe with an appropriate cleaner is recommended for optimal adhesion. Apply the sealant using a standard caulk gun, maintaining steady pressure for a consistent bead. For best results, mask adjacent areas to ensure clean lines and easy cleanup.
Compatibility
Sikaflex 522 is highly compatible with a wide array of materials commonly found in caravans and motorhomes. These include:
- Timber: Wood panels, framing.
- Glass: Windows, skylights.
- Metals: Aluminum, steel, metal primers.
- Paint Coatings: Various painted surfaces (ensure paint is fully cured).
- 2-Part Systems: Certain composite materials.
- Ceramic Materials: Tiles, porcelain.
- Plastics: Many common plastic types used in vehicle construction. Always perform a small test on sensitive plastics to ensure compatibility.
Care
Once applied, the sealant will begin to cure. Avoid disturbing the freshly applied sealant. Specific cure times will depend on ambient temperature and humidity. Always refer to the product's technical data sheet for precise curing instructions and recoating times. For cleaning uncured sealant, a suitable solvent may be used. Cured sealant is generally very durable and requires no special care other than routine cleaning of the vehicle surface. Store unopened cartridges in a cool, dry place.
