One Part Flexible Adhesive is a highly polymer fortified wall and floor tile adhesive mortar; containing specially formulated Rock-TiteTM, which requires only the addition of water in order to achieve a high level of flexibility, water resistance and strength (usually only achieved through the addition of polymer admixtures). It is ideal for tiling in high duty areas such as swimming pools, commercial showers and locations where thermal variation may occur, i.e. underfloor heating system applications

Key Features

  • Coverage (dependant on bed depth and surface regularity):
    Walls; approx. 2.85kg per m2
    Floors; approx. 4.4kg per m2
  • Setting time 16 to 24 hours
  • Ease of use pot life of up to 4 hours
  • Easy to use – just add water
  • Highly flexible
  • Water resistant
  • Extremely strong and non-slip
  • Suitable for fixing fully vitrified porcelain, ceramic and natural stone tiles; including limestone and marble
  • Suitable for heavy duty commercial uses i.e. swimming pools, commercial showers etc.
  • Suitable for use with underfloor heating applications
  • Suitable for use on walls and floors
  • Suitable for internal and external use

Quality and Standards

One Part Flexible Adhesive conforms to classification BS EN 12004 C2TE


Surface Preparation

  • Allow all new substrates to dry fully i.e. new concrete should be allowed to dry for a minimum of 6 weeks and new cement screeds for a minimum of 3 weeks
  • Ensure the surface is clean, dry and strong enough to support the combined weight of the tiles, adhesive and grout
  • Check the substrate is flat and true
    – on floors, any gaps exceeding 3mm under a 2m straight edge should be levelled using Pro 50 Floor Leveller
  • Prime any porous or dusty surfaces, i.e. plaster, plasterboard, vinyl sheets, plywood overlay, anhydrite and gypsum screeds, with Norcros Prime Bond
  • In wet areas or those of intermittent wetting, moisture sensitive backgrounds i.e. plaster should be waterproofed using Norcros Wet Seal

Mixing and Application

  • Mix the product with clean cold water; 20kg of adhesive powder to 5.5 litres of water (mix until smooth, lump-free consistency achieved)
    Note. the product has an ease of use pot life of up to 4 hours
  • Using a suitably notched trowel, apply the adhesive to the wall or floor surface
  • Comb to required bed thickness (normally between depths of 3-8mm but can be used up to 12mm thickness in isolated areas) ensuring ribs all run in one direction
  • Spread only an area that can be covered within the open time; before the adhesive begins to set and form a skin (if a skin has formed, simply remove adhesive and apply fresh layer)
  • Press tile firmly into the ribs of the adhesive and into position, with slight twisting/sliding action to ensure optimum adhesive contact
    Note. lift one tile to check the adhesive is in total contact with both substrate and tile, creating a void-free solid bedding
  • Ensure you have left adequate joint spaces between tiles for grouting
  • Clean off surplus adhesive from tile face and between tile joints
  • Tiles can be grouted as soon as the adhesive bed is set, typically 24 hours


One Part Flexible Adhesive is a slow setting (24 hour) tile adhesive - for a faster setting time and quick tile installation process use Rapid Porcelain & Stone Adhesive

One Part Flexible Adhesive is a thin bed tile adhesive (3-8mm) - for bed depths ranging from 5-25mm use Thick Bed Stone & Porcelain Adhesive

When fixing to light coloured natural stone always use the white One Part Flexible Adhesive
