Frequently asked questions about the Silicones category
Silicones — what are they and what are they used for in the "Silicones" category?
Silicones — are silicone-based sealants, adhesives and mastics used to seal joints, bond materials, and protect against moisture and high temperatures. The category includes sanitary, universal, high-temperature and specialty silicones for construction, plumbing and assembly applications.
What types of silicones are available and how do sanitary silicones differ from universal ones?
The range includes sanitary silicones (mould-resistant, for bathrooms and kitchens) and universal silicones (for windows, facades and general repairs). Sanitary grades often contain biocides for mould protection, while universal grades prioritise adhesion and elasticity for movement joints.
Which silicones are suitable for bathroom and kitchen?
Use sanitary silicones like SAN.SILIKOON CERESIT CS25 or MOMENT SANITARY from the Silicones category; they are moisture- and mould-resistant and intended for tile joints, sanitary fixtures and water-exposed seams.
Can I use a universal silicone for windows and doors?
Yes, universal silicones such as MAPEI MAPESIL AC-112/AC-123 are suitable for sealing window and door frames; they adhere to glass, metal and plastics and accommodate thermal movement.
Which silicones withstand high temperatures (for ovens, exhausts)?
The category includes high-temperature and specialty silicones; check product descriptions for 'high-temperature' ratings. These formulations are designed for durable sealing under sustained heat in ovens and exhaust systems.
Which silicone is best for bonding metal and glass?
Choose universal or structural silicones with strong adhesion, such as MAPEI MAPESIL series; check compatibility in the product description and whether a primer is required for difficult substrates.
Are there products to remove old silicone in the assortment?
Yes — the range includes silicone removers such as SILIKOONIEEMALDI KIILTO PRO 400ml to help strip old sealant and prepare joints for new silicone.
Which cartridge volume should I choose for small repairs and large joints?
For small repairs use 20–80 ml tubes (e.g. TECHNICQLL 20ml or MOMENT RE-NEW 80ml). For large joints and professional work choose 280–310 ml cartridges (CERESIT 280ml, MAPEI 310ml) as they are more economical for bigger jobs.
How should I prepare the surface before applying silicone?
Remove dirt, grease and old sealant; degrease and dry the surface. Use a primer where adhesion is poor, and for sanitary joints follow mould-prevention instructions as specified.
How do I choose silicone colour and are there colouring products in the category?
The category offers colours (white, transparent, grey) and tinting/renewal products like MOMENT RE-NEW 80ml for refreshing old joints. Choose colour to match materials and aesthetics; use tinting products for colour corrections.
