Benfer Benferflex +S1 Tile Adhesive is a highly flexible, multi-purpose adhesive, applicable in thickness up to 20 mm, that can be used as flow bed adhesive.
Benfer Benferflex +S1 Tile Adhesive is a powder adhesive, consisting of cements, graded particle size aggregates, synthetic resins and special additives. It has been formulated and developed for rapid, reliable installation of almost the totality of ceramic material, even on non-absorbent substrates and onto substrates subject to slight dimensional variation. The high resistance to vertical sliding allows to tile from the top down.
Thanks to its particular composition, Benfer Benferflex +S1 Tile Adhesive can be mixed with a higher percentage of water to allow for complete “wetting” of the back of the tiles, even on large size formats, with no need for double buttering.
Benfer Benferflex +S1 Tile Adhesive has many key features:
- Highly deformable
- Multi-purpose, can be used as self soaking adhesive
- Highly resistant to lowering, with outstanding application properties
- Long open time
- Very easy to use
- For heated substrates
- Dust reduced
- Tested in accordance with European standard EN 12004, C2 TE S1
- High yield
- For exterior and interior use
- Interior and exterior walls and floors
- Heavy duty areas
- On top of old wall and floor tiles
The substrates must be solid, load-bearing, free from oil, grease and dust. Any paint-work must be in good condition, washed and degreased. If this is not the case, the paint must be carefully removed. Gypsum or calcium sulphate based substrates must be treated beforehand, this also includes absorbent substrates.
