Sanitary Silicone Akemi fog 82 and its emission classification
On housing and refurbishment work nobody asks about emission classification. On projects with indoor air requirements — nurseries, schools, care homes, certified buildings — it is the first thing asked. And then an abbreviation on the cartridge decides whether the product may be installed at all.
Fog 82 is one of AKEMI's soft greys in this range. The emission classification applies to the whole Sanitary Silicone.
Application area
AKEMI® Sanitary Silicone is a special joint-sealing material for expansion and connecting joints in kitchens, living and sanitary areas on ceramic tiles. Approved for interior and exterior use. Excellent and durable adhesion on non-porous silicate materials: glass, glazed ceramics, tiles, clinker, glass ceramics, email, porcelain and aluminium.
EMICODE EC1PLUS and emission class A+: what is on the cartridge
GEV EMICODE® EC1PLUS — very low emission. EMICODE is the classification system of GEV (Association for the Control of Emissions in Products for Flooring Installation). EC1PLUS is the strictest level within that system; AKEMI lists the Sanitary Silicone in this classification.
Emission class A+. This is the French VOC labelling, mandatory on construction products in France. There, A+ denotes the lowest emission level. The manufacturer lists both classifications — EMICODE and VOC France — side by side in the data sheet.
REACH. The product is compliant with regulation (EU) No. 1907/2006.
What this means for the finished joint. After hardening the sealant is odourless and physiologically harmless, and the hardened sealant is not harmful to health. During application, nonetheless: use AKEMI® The Liquid Glove to protect your hands — and read the Safety Data Sheet. Acetic acid is released during hardening.
What the data sheet does not say. Whether and how these classifications count towards a specific building certification is not covered by the Technical Data Sheet. For evidence towards clients or certifiers, refer to the manufacturer's documentation; our e-commerce team will help you obtain it.

Application in brief
- Contact surfaces dry, clean, free of grease and dust; clean with AKEMI® Cleaner A (tiles, ceramics, glass, non-painted wood, metal) or Cleaner I (plastics, painted surfaces).
- Joint size min. 5 x 3 mm. Insert back-filling cords to avoid adhesion on three flanks: closed-cell PE in damp rooms and outdoors, otherwise open-cell PUR. Mask off the joint edges.
- Apply at +5 °C to +35 °C with dry flanks. Smoothen within 10–15 minutes using a smoothing rubber and smoothing agent; remove excess smoothing agent.
- Remove the masking tape before the skin forms, pulling towards the joint. Clean tools with AKEMI® Cleaner A.

Important restrictions
For professional use only. Not suited for porous, absorbent surfaces like natural and artificial stone — danger of discolouring in the marginal zone. AKEMI offers dedicated neutral cross-linked products for natural stone.
- Releases acetic acid during hardening — not on or near acid- or corrosion-sensitive materials (iron, copper, brass, zinc, lead, concrete, materials containing lime or cement).
- No sufficient adhesion on silicone, PE, PP, PTFE, butyl rubber, neoprene, EPDM or plasticised plastics.
- Discolouration on tar- and bitumen-coated surfaces as well as elastomers (EPDM, APTC, neoprene).
- On wood, metal, paints, plastics, stainless steel and sanitary acrylate no general prediction is possible — test adhesion and compatibility beforehand.
- Not for the construction of aquariums. Read the Safety Data Sheet.

What does EMICODE EC1PLUS mean?
It is the "very low emission" classification within the GEV system.
The manufacturer lists AKEMI® Sanitary Silicone as very low emission according to GEV EMICODE® EC1PLUS. EMICODE is the system of the Association for the Control of Emissions in Products for Flooring Installation; EC1PLUS denotes its strictest level. The classification applies to every shade in the range.
What is emission class A+?
The French VOC labelling for construction products — A+ is the lowest emission level.
The Technical Data Sheet lists it under "VOC France: emission class A+" alongside the EMICODE classification. Both labels concern volatile organic compounds but come from different systems, which is why they are stated separately.
Does the joint still smell once hardened?
No — after hardening the sealant is odourless and physiologically harmless.
The vinegar smell during application comes from the acetic acid that the acetate cross-linked product releases as it hardens. Once hardened through, the sealant is odourless, physiologically harmless and, according to the manufacturer, not harmful to health.
Do I need gloves during application?
The manufacturer names AKEMI® The Liquid Glove for hand protection.
In addition: read the Safety Data Sheet before handling or using this product. The favourable emission classification of the hardened product changes nothing about protective measures during application — acetic acid is released at that stage.
