Question 1

What's the difference between C0, C1, and C2 tile adhesive?

Accepted Answer

C0 is a general-purpose adhesive for indoor floors and walls; C1 offers extra strength for indoor/outdoor use with larger-format tiles; C2 is our super-strong grade for large sintered stone and vitrified tiles up to 1200 x 2400mm. The higher the grade, the greater the bond strength and tile-size capability.

Question 2

Which mortar should I use for AAC blocks vs. concrete walls?

Accepted Answer

For AAC (autoclaved aerated concrete) blocks, we recommend our Lightweight & Thin-Coat Plastering Mortar, Light-Plastered Thin-Coat Mortar, or 4-in-1 Masonry Plastering Mortar. For concrete or brick walls, our M5-M20 Masonry Plastering Mortar (2-in-1) or Thin-Coat Plastering & Masonry Mortar are better suited.

Question 3

Do you offer products that combine masonry and plastering in one bag?

Accepted Answer

Yes, several of our products are dual-purpose — including the 4-in-1 Masonry Plastering Mortar, M5-M20 Masonry Plastering Mortar (2-in-1), and Thin-Coat Plastering & Masonry Mortar — reducing the need to stock separate materials for bonding and finishing.

Question 4

What packaging sizes are available across your product range?

Accepted Answer

Packaging varies by product, ranging from 20KG (tile adhesives) and 25KG (self-leveling and waterproof mortars) up to 40KG and 50KG (masonry, plastering, and floor leveling mortars). Check each product page for exact specifications, or contact us for bulk packaging options.

Question 5

Can Chenson customize a mortar formula for specific climate or project conditions?

Accepted Answer

Yes. Our Changxun TC (Technical Center) provides data-driven formula adjustments for extreme conditions — such as high humidity, high temperature, or specialized bond-strength requirements — based on your project specifications.

Question 6

Which standards do Chenson's mortars comply with?

Accepted Answer

Our products comply with national and industry standards including GB/T 25181-2019 (Ready-mixed Mortar), JC/T 547-2017 (Ceramic Tile Adhesives), JC/T 986-2018 (Cementitious Grout), and JC/T 984-2011 / JG/T 158-2013 (Waterproof & Anti-crack Mortars).
