Kiilto PL 250 Laattaliima is a two-component, solvent-free, M1-labelled and fire-classified polyurethane adhesive, which gives a strong, yet elastic bond. Due to its paste formula, it is ideal for trowel application for walls and ceilings. Used in conjunction with Kiilto PL 250 Laattaliimakovete hardener. Kiilto PL 250 Laattaliima is used for the gluing of, e.g., metals, PVC and concrete as well as the gluing of ceramic and glass mosaic tiles on Kiilto waterproofing membranes. Adhesion strength complies with EN 12003 and EN 1348 standards after water-stress tests. The adhesive is fire classified according to IMO FTPC Resolution MSC.61 (67) Part 2 and Part 5 and has an MED certificate (Wheelmark).

Instructions for use

The surfaces to be bonded must be clean and dry. Remove oxidations, grease and other impurities using Kiilto Maalarinpesu, solvent or by sanding. When applying Kiilto PL 250 tile adhesive on concrete, relative humidity of the surface can be max. 90%. Stir Kiilto PL 250 Laattaliima adhesive and carefully add the hardener. Then mix thoroughly. Apply the mixture with a trowel or other application tool on one or both surfaces to be bonded. Remove fresh adhesive stains with a dry cloth and clean the surfaces with acetone or xylene. Hardened adhesive can only be removed by mechanical means. We recommend using adhesive at room temperature. However, the gluing can be carried out at lower temperatures (even at +5–10 °C), but then the curing time will be much longer and spreading properties will suffer.

Environment and safety
