AltroFix 19 Plus technical data sheet


Last edited: January 2021


For use with all Altro safety flooring (in areas subject to spillages), and Altro materials which can be bonded to Altro Everlay™ underlayment.



AltroFix 19 Plus is a solvent and water-free, two-part polyurethane adhesive supplied in the correct quantities for mixing. Both A and B parts are held within the container.
Supplied in 1.5kg, 3kg, and 6kg units.

Subfloors and site conditions - must conform with BS 8203:2017
AltroFix 19 Plus can be used on dry, dust-free subfloors such as sand/cement, flooring grade asphalt (flooring grade 1 to BS 6925:1988), granolite, plywood, chipboard, hardboard, metal and epoxy surfaces, damp-proof membranes and power float concrete. It is important that the subfloor is as smooth as possible, any undulation may cause pockets of adhesive to form bubbles in the floor covering.

Mixing of parts A and B

Part A is a viscous paste. Part B is a fluid liquid supplied in silver foil sachets. Stir part A thoroughly. Transfer part B into large container holding part A and mix thoroughly until a uniform consistency is obtained throughout. A drill with a paddle attachment should be used to ensure complete mixing. Scrape sides thoroughly during this process. Care should be taken to avoid spillage when mixing, as staining of the floor surface may occur.


Apply adhesive to subfloor only, as soon as possible before adhesive thickens (within 15-20 minutes of mixing, depending on temperature). Spread evenly with a notched trowel. It is important to use a small notched trowel to avoid entrapment of air between the floor covering and subfloor. Place floor covering into wet adhesive, do not roll, and expel all trapped air with the use of a flat wooden or Perspex trowel, wrapped in a soft textile material which has been pre-wetted. Limit trafficking of the floorcovering when the adhesive is still fresh. If any corners, joints or edges are lifting while the adhesive is setting, these must be weighted. Leave weight undisturbed and the floorcovering traffic free until the adhesive has set. Where this procedure is not followed, special care should be taken to check all joints etc, before leaving site for the day.
