Tile Adhesives — EN 12004-1 Classification

Selecting the right tile adhesive is the most critical step in a durable installation. The European standard EN 12004-1 gives every product an alphanumeric code (e.g. C2TES1) describing its chemistry, performance and special features.

Base Type

C — Cementitious (powder + water/latex)
D — Dispersion (ready-to-use paste)
R — Reaction resin (epoxy/PU)

Performance Class

1 — Normal performance
2 — Improved (large/porcelain tiles, exterior)

Special Features

F — Fast-setting
T — Reduced slip
E — Extended open time

Deformability

S1 — Deformable (2.5–5 mm)
S2 — Highly deformable (>5 mm)

Code	Meaning	Common Application
C1	Standard Cementitious	Standard ceramic tiles on indoor concrete floors.
C2	Improved Cementitious	Porcelain tiles or outdoor patio installations.
D1	Standard Dispersion	Ceramic wall tiles in a dry interior room.
R2	Improved Reaction Resin	Industrial kitchen floors exposed to chemicals.
C2T	Improved, Non-Slip	Large-format tiles on bathroom walls.
C2F	Improved, Fast-Setting	Retail floor tiling requiring next-day opening.
C2TES1	Improved, Non-Slip, Extended Open Time, Flexible	The all-rounder — large porcelain over underfloor heating.

Tile Grouts — EN 13888 Classification

Grout locks tiles together, seals the joints and provides the final finish. EN 13888 classifies grout by chemical base, performance class and special characteristics.

Chemistry

CG — Cementitious grout
RG — Reaction-resin (epoxy), 100% waterproof

Class

1 — Normal
2 — Improved (polymer-modified)

Special

W — Reduced water absorption
A — High abrasion resistance

Code	Meaning	Ideal Application
CG1	Standard Cementitious Grout	Dry living-room floors or basic wall tiles.
CG2	Improved Cementitious Grout	Residential floors, including underfloor heating.
CG2W	Improved, Water-Repellent	Bathroom walls and kitchen backsplashes.
CG2A	Improved, Abrasion-Resistant	Retail floors and busy office lobbies.
CG2WA	Water-Repellent & Abrasion-Resistant	Wet rooms, heavy traffic and outdoor patios.
