Question 1

What is Henkel Polybit CM9 20kg Tile Adhesive Grey and what is it used for?

Accepted Answer

Henkel Polybit CM9 is a dry-mixed cementitious tile adhesive sold in a 20 kg grey tub. It is designed for interior and exterior floor tiling and can bond ceramic, mosaic, porcelain, and natural stone tiles. The product offers a smooth mix, long open time, and strong adhesion for durable tile installations.

Question 2

What tiles and substrates can CM9 bond to?

Accepted Answer

CM9 is suitable for a wide range of substrates commonly used in floors, including concrete, cementitious backer boards, and masonry substrates. It supports both interior and exterior floor tiling and is applicable to walls as well when used according to the project requirements.

Question 3

What are the main features and benefits of CM9?

Accepted Answer

Key features include high bond strength to prevent tile loosening, flexible application for wall and floor use, a smooth easy-to-mix consistency, quick setting characteristics for faster progress, resistance to water and heat, crack-resistance to accommodate substrate movement, easy cleanup with water before set, and a grey color that helps achieve a uniform look on dark or neutral tiles.

Question 4

How do I install CM9 tile adhesive?

Accepted Answer

For installation, mix the dry CM9 with clean water to a smooth, lump-free paste, letting it rest briefly before remixing. Apply the adhesive with an appropriate notched trowel and back-butter larger tiles for best contact. Place tiles, align as needed, and allow the adhesive to set before grouting according to the project conditions and tile size.

Question 5

What safety precautions should I take when using CM9?

Accepted Answer

Wear protective gloves and eye protection when handling the wet adhesive, and work in a well-ventilated area. Avoid skin contact; wash thoroughly with water after use. Keep out of reach of children. Dispose of packaging and any leftover material in accordance with local regulations.

Question 6

Can CM9 be used outdoors, and how does it perform in wet areas?

Accepted Answer

Yes, CM9 is formulated for indoor and outdoor floor tiling. It is designed to perform in wet or high-moisture areas, providing durable adhesion and resistance to water exposure when installed under appropriate conditions.

Question 7

How does CM9 20kg compare to CM9 25kg in terms of value and usage?

Accepted Answer

CM9 25kg offers the same adhesive performance as the 20kg version but provides greater value for larger projects due to the larger pack size. For bulk tiling jobs, the 25kg bag can reduce frequent reorders while delivering consistent performance. See the alternative here: https://fepy.com/product/henkel-polybit-cm9-25kg-grey

Question 8

Question 9

What should I consider for choosing the right CM9 packaging size for my project?

Accepted Answer

Choose a packaging size based on project scope, tile size, and application area. For larger areas, a bigger bag (like the 25kg option) can reduce waste and handling time, while smaller jobs may be more cost-effective with the 20kg bag. Always plan for extra adhesive to account for waste and variation in tile layout.

Question 10

What is the recommended approach for mixing and applying CM9 in challenging conditions?

Accepted Answer

In challenging conditions (extreme temperatures or humidity), ensure surfaces are prepared and within the recommended temperature range. Mix to a smooth consistency, avoid over-watering, and work in manageable sections to maintain a workable open time. Use proper trowel size and back-butter for large-format tiles to ensure full contact with the substrate.

Question 11

How should I clean tools and remove dried CM9 from mixers and trowels?

Accepted Answer

Clean tools with water while the adhesive is still fresh and before it sets. For dried residue, scrape off as much as possible and use water or a recommended cleaner while wearing protective gloves. Avoid letting the adhesive cure on tools, as it becomes harder to remove.

Question 12

What is the return policy for tile adhesives purchased on Fepy?

Accepted Answer

Fepy generally supports returns on tile adhesives under standard terms, typically for unopened items within a reasonable window and in original packaging, subject to regional terms and conditions. For exact terms, refer to the store’s published return policy and your purchase details.
