Kerakoll Standard Set Setaflex is a flexible cement-based wall and floor tile adhesive that has been improved with a polymer to enhance its adherence and non-slip qualities. Standard Set Setaflex is the best option when longer working times are needed because it is designed to deliver a prolonged pot life of roughly three to four hours.
It is a unique adhesive designed to bond a wide range of tiles, including ceramic, porcelain, and natural stone tiles, to solid substrates like concrete and sand/cement screed as well as substrates with restricted movement and/or vibration, like plywood overlay, timber framework, and underfloor heating systems. For spaces like swimming pools and wet rooms that experience continuous or extended damp conditions, Kerakoll Standard Set Setaflex is the best option. Frost has no effect on it once it has set, and it can be used both indoors and outdoors.

Coverage:
Grey (mixing ratio of 23%) – approx 1.2kg/m2
White (mixing ratio of 23%) – approx 1.2kg/m2
Intended use
Substrates must comply with BS 5385, parts 1-5, be level, cured, undamaged, compact, rigid, dry and free from any debonding agents. It is good practice to dampen highly absorbent concrete substrates or apply a coat of Primer A Eco. Anhydrite substrates must have a residual humidity ≤ 0,5 CM-%. Cement-based screeds must have a residual humidity ≤ 2 CM-%. Anchored substrates must comply with BS 8204 and anhydrite with underfloor heating must have a residual humidity ≤ 0,3 CM-%.
Mixing water (EN 12004-26):
Grey ≈ 22% – 23% by weight
White ≈ 22% – 23% by weight
Mixing water on-site:
Grey ≈ 4.4 – 4.6 l/1 bag
White ≈ 4.4 – 4.6 l/1 bag
The amount of water to be added, indicated on the packaging, is an approximate guide. It is possible to obtain mixtures with consistency of variable thixotropy according to the application to be made.
To guarantee structural adhesion it is necessary to apply a layer of adhesive sufficient to cover the entire back of the coating material.
Large, rectangular sizes with sides > 60 cm and low thickness sheets may require adhesive to be applied directly to the back of the material.
Check samples to make sure the adhesive has been transferred to the back of the material.
Create elastic expansion joints:
– ≈ 10 m2 in external applications (approx. 3×3 m)
– ≈ 40 m2 in internal applications (8×5 m) with
underfloor heating
– ≈ 100 m2 in internal applications (10×10 m)
without underfloor heating
– every 8 metres in long, narrow applications. Respect all structural, fractionising and perimeter joints present in the substrates.
Pre-treatment of special substrates
Timber (internal use only): Keragrip Eco Metal (internal use only): Keragrip Eco Gypsum and anhydrite (internal use only): Kerakoll Primer A Eco
PVC (internal use only): Keragrip Eco
As treating special substrates is difficult to classify in a standard manner, it is always advisable to contact Kerakoll Global Service and/or request a site inspection by a GreenBuilding Consultant. In any case it is essential to carefully read the technical data sheet on how to use the indicated primers properly.
Materials and special substrates
Natural stones and recomposed materials: materials that are known to be subject to deformation or staining due to water absorption require a quick-setting or reactive adhesive.
Natural stone in general may have characteristics that vary even with reference to materials of the same chemical and physical nature. For this reason it is essential you consult Kerakoll Global Service to request specific indications or to carry out a test on a sample of the material.
In the absence of specific indications from the manufacturer, natural stone slabs with reinforcement layers, in the form of resin coating, polymer mesh, matting, etc. or treatments (for example damp courses, etc.) applied on the laying surface must be tested in advance to ensure they are compatible with the adhesive. Check for the presence of any really consistent traces of rock dust created during cutting, and remove them if found.
Waterproofing products: adherent and floating polymer sheets, liquid bitumen and tar-based sheets or membranes require application of a laying screed on top. In the case of reactive waterproofing products (such as RM waterproofing according to EN 14891) it is necessary to use a reactive adhesive.

Fantastic customer service and fast delivery, highly recommend
Great prices and a super quick delivery turnaround. Communication was perfect aswell. So much so I’ve ordered again.
They actually answered the phone, were polite, knowledgeable and the order was delivered in full and on time. Would fully recommend both on price and service. Thank you.
BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
