Detergent or soap water treatments are not recommended.

Compatilibity Testing

Incompatibility of glazing materials can lead to sealant discoloration and/or loss of adhesion. To help protect against these problems and to ensure compatibility, HOMEY will also test and provide information on the compatibility of accessory materials (gaskets, spacers, etc.) and other YOUNUO Silicone Sealants.


Uncured silicone can irritate the eyes and skin. If contact is made with eyes, flush with water for 15 minutes and seek medical advice. Use in well ventilated area and keep out of reach for children.
