Weber Weberset Mosaic C2 Tile Adhesive / 25KG

Product Overview

Weberset Mosaic is a single-component waterproof tile adhesive and grout designed specifically for mosaics and small tiles. Traditional installation requires bonding tiles first with adhesive, then grouting separately — a time-consuming process. Weberset Mosaic combines both steps into one, significantly simplifying the workflow. The cement-based formula only requires clean water to mix into a smooth paste, with no additional additives needed. The product offers high bond strength, excellent anti-slip properties, and low shrinkage to reduce cracking. Tested to be mould-resistant (per manufacturer data), making it suitable for humid environments.

Key Features

• Two-in-one bonding and grouting — complete both bonding and grouting in a single step, eliminating the separate grouting process
• Single-component, just add water — mix with clean water to the specified ratio for consistent, easy-to-control quality
• Waterproof formula — suitable for bathrooms, shower rooms, and other wet areas
• High bond strength — secure adhesion for mosaics and small tiles
• Anti-slip — tiles stay in place on vertical surfaces during installation

FAQ

How does mosaic adhesive differ from regular tile adhesive?

Mosaic adhesive is a two-in-one product (bonding plus grouting), purpose-designed for mosaics and small tiles — just spread and grout in one operation. Regular tile adhesive only bonds; grouting requires a separate product. Using dedicated mosaic adhesive saves an entire work step.

Can it be used for large tiles?

Weberset Mosaic is designed for mosaics and small tiles. For large-format tiles, use Weberset 303 or 383 which provide the bond strength and coverage suited to larger formats.

Do I need to buy separate grout?

No. Weberset Mosaic already includes grouting capability — bonding and grouting are completed in one step, so there is no need to purchase separate grout.
