Skimcoat Primer EBH – 401mortar is the ready mix dry cementitious mortar using before plastering on AAC wall Main components of EBH – 401 mortar include cement, fine sand, and general-purpose additives.

Mortar products are manufactured on an industrial scale according to European standards, adhere to strictly monitoring processes to ensure product quality, and limit risk of mixing at work.


Skimcoat Primer EBH – 401mortar is a specialized product line that is compatible with and suitable for the AAC wall. The skimcoat layer is applied or rolled thinly onto the surface of AAC wall before performing the plastering work with regular sand cement mortar.

The additive component in mortar EBH-401 prevents the phenomenon of dehydration of the sand and cement plastering layer due to AAC block absorbing water, making AAC lightweight concrete wall plastering work simple, familiar, and similar to traditional bricks.

Skimcoat Primer EBH – 401 mortar overcomes phenomenon incompatibility when applies directly sand-cement mortar on the surface of AAC block wall, limit cracking and blistering, sure for aesthetic appeal.

Packing Method:

EBH-401 mortar is packed in a moisture-proof paper bag, 25kg per bag to facilitate transportation, storage, and use.
