Troubleshooting
Sealant not adhering well
Ensure surfaces are thoroughly cleaned, dry, and free from dust, grease, or old sealant. Reapply if necessary after proper surface preparation.
Uneven or messy bead
Practice applying with a sealant gun. Use a smoothing tool or a damp cloth (with a little soapy water) immediately after application to create a neat finish. Remove excess promptly.
Mould appearing on the sealant surface
While resistant, extreme conditions may still lead to surface discolouration. Clean the area with a mild detergent and water. Ensure good ventilation in the area to reduce humidity.
Sealant is too stiff to apply
