ARDEX ‘RAPIDRY FORMULA’ CEMENT SYSTEMS
ARDEX ‘RAPIDRY FORMULA’ CEMENT SYSTEMS
Products with the ‘Rapidry Formula’ logo
incorporate unique technology:
‘Rapidry Formula’ products have the ability
to totally bind the water used for mixing
This means rapid hardening and drying regardless of thickness for commercial and
industrial flooring systems
This means elimination of the risk of water discoloration, staining and efflorences when
fixing natural stone
Surface laitance on concrete
Not normally so very evident
and not removable by brushing
Scrabbling equipment
Appearance on Site
Result of background shrinkage after fixing floor tiles
Moisture from substrate reacts with minerals in the stone
Permanent moisture staining from screed
Permanent Staining from moisture in screed
Reasons for the Discolouration of Natural Stone
A. Dirt entrained from above, incorrectly sealed or maintained
B. Rising moisture releases minerals contained in the natural stone
C. Contamination carried up from the mortar bed (organic substances, metal)
D. Moisture from the substrate (screed, concrete or adhesive), the grouting compound and plasticiser in the silicone will discolour edge areas, known as `picture framing`
E. Calcium hydroxide in the mortar bed is deposited on the surface and becomes calcium carbonate (known as lime bloom or efflorescence)
F. Moisture spots caused by freeze/ thaw activity

Smoothing/Self levelling
• CL 11
• K15
• K80
• K301
P 82 Priming and bonding agent
For internal use only
Two-part water-based synthetic dispersion primer and
bonding agent
Seals substrates and acts as an adhesive bridge
Nonflammable
Suitable for dense or smooth surfaces for receiving
ceramic tiles or smoothing compounds
Use to prime rigid metal flooring grade asphalt, suitable
paint coatings, glazed tiles, power floated concrete,
adhesive residues etc.
P51 Primer and Bonding Agent
• Improves Adhesion
• Inhibit Penetration of water
• Used as pore sealer on floor surfaces to prevent air bubbles rising
through the sub floor smoothing compound
• Mixed with water to prepare internal surfaces to receive Cement – based
levelling compounds, adhesive,screeds as well as plaster material
• To prolong flow life and workability

K15 Self levelling Sub- floor Smoothing Compound
• Rapid hardening – workable in approx. 2 hours
• Rapid Drying – receives floor coverings within 24 hrs regardless of thickness
• Rapidry Formula – It is the ability of the mortar to totally bind the water used for
mixing
• Prime with P82 non porous or P51 primers for porous
• Used in internal sub floor such as concrete, cement/sand screed, quarry tiles etc.
• Applications include smoothing tampered , uneven, damaged or rained in-situ
concrete sub floors
• Can be applied from 3mm to10mm
• Coverage approx. 1.5kg/m2/mm i.e. 22kg bag /5m2/3mm thick
