Evidence Base

Category estimate

No product evidence is attached to this generic material, so nothing on this card is numerical. The guidance below is qualitative — an AI-assisted category profile — for early design discussion, not for figures.

Next step: request a current product EPD or manufacturer carbon declaration, or swap in a branded product that holds one.

What's missing (3)

•No current product EPD is recorded.
•No quantified carbon result is recorded.
•No product-specific circularity or material-health claims are recorded.

Service Life — the B4 Replacement Input

20 years · basis not recorded

≈3 installations over a 60-year building study period.

B4 (replacement) follows the building, not the product: an assessor multiplies replacement cycles by project quantities. This record supplies the service life and does not compute B4.

Design & Specification Notes

Thin build-up continuous finish using reduced-cement or lime-enhanced binders for walls and low-traffic interior floors.

Typical Uses

•Seamless interior finish
•Wet areas
•Low-build overlays

Key Performance

Seamless, low-build finish for wet areas.

Watch For

•
Hairline cracking over moving substrates
Use mesh-reinforced base coats and verify substrate movement tolerance.
•
Uneven sheen from inconsistent sealing
Apply manufacturer system coats to tested coverage rates with sample sign-off.

Specification Actions

•Provide EPD or manufacturer carbon declaration comparing binder content against standard microcement systems.
•Verify low-VOC sealer/coating and crack-bridging substrate preparation for long-term durability.
•Design for local repair and recoating rather than full substrate removal at refurbishment cycles.

Indicative Health & Indoor Air

low Risk

Inert once cured. Confirm low-VOC sealers and safe handling of fine powders during mixing/application.
