Materials

Product Information
Application

Kiilto KeraPro is a one-component, fast curing waterproofing membrane for manual and machine application prior to tiling in interior wet areas. The substrate must be dry, absorbent, free from dust and even.
All materials that might impair adhesion of the waterproofing membrane must be removed. Ensure that the construction and substrate are suitable for waterproofing and tiling. Underfloor heating is laid under the waterproofing membrane.

Instructions and Safety
Instructions for use

Walls:
If needed, sand and/or smooth uneven substrates with Kiilto wall plaster suitable for use under waterproofing and tiling. Prime dry wall surface prior to waterproofing with Kiilto Keraprimer or Kiilto PrimerOne as per instructions. Ensure that the primer layer is fully dry, before starting the waterproofing work.

Stir KeraPro before use. Apply Kiilto KeraPro on walls in vertical corners, construction board and other substrate material joints and junctures. Press Kiilto Nurkkavahvikenauha tape to fresh waterproofing membrane and ensure that it is thoroughly wetted. Clean and prime the inlets. With pipe inlets, cut an approx. 10 x 10 cm reinforcement piece and cut a hole in the middle, approx. 4 mm smaller than the pipe's outside diameter. Press the inlet reinforcement piece to the fresh waterproofing membrane and ensure that it is thoroughly wetted. You can also use pre-fabricated inlet reinforcements. It is also possible to seal up wall inlets using Kiilto XPU adhesive sealant prior to applying Kiilto Kerafiber.

Apply a thin layer of KeraPro (approx. 0.2 mm) on the entire area to be waterproofed with a roller and let dry (colour change). Apply a second, thicker coat of KeraPro (approx. 0.3 mm), so that the final coat thickness is 0.5 mm, and let dry (colour change). Let the first coat dry for approx. one hour. Let the second coat dry for approx. two hours. Drying time depends on layer thickness and prevailing conditions. Check that the membrane layer is consistent. Seal any thin/porous spots and allow to dry thoroughly. The dry membrane layer must be 0.5 mm at the minimum.

Fix wall tiles with Kiilto Saneerauslaasti, Superfix DF, Kerapid Pikasaneerauslaasti, Lightfix or HighFlex S2 DF. After the tiling adhesive has dried, grout the tiles with Kiilto Saumalaasti and seal vertical wall corners and inlets with Kiilto Saniteettisilikoni.

Floors:
If needed, sand and/or smooth uneven substrates with Kiilto floor levelling compound. Prime dry floor surface prior to waterproofing with Kiilto Keraprimer or Kiilto PrimerOne as per instructions. Let the primer dry fully before starting the waterproofing work.

Stir KeraPro before use. Apply Kiilto KeraPro in horizontal corners and inlets and press Kiilto Nurkkavahvikenauha tape to fresh waterproofing membrane and ensure that it is thoroughly wetted. For inside and outside corners you can also use pre-fabricated corner pieces. Clean and prime the inlets. Inlets on the floor can be sealed also with Kiilto XPU fix before application of Kiilto KeraPro. For floor drain use self-adherent Kiilto Kaivolaippa. With metal floor drains use self-adherent Kiilto Kaivolaippa or butyl tape.

Apply a thin layer of KeraPro (approx. 0.2 mm) on the entire area to be waterproofed with a roller and let dry (colour change). Apply a second, thicker coat of KeraPro (approx. 0.3 mm), so that the final coat thickness is 0.5 mm, and let dry (colour change). Let the first coat dry for approx. one hour. Let the second coat dry for approx. two hours. Drying time depends on layer thickness and prevailing conditions. Seal any thin/porous spots and allow to dry thoroughly. Waterproofing membrane layer on the floor drain area must be 1.2 mm at the minimum, elsewhere on the floor 0.5 mm. Before tiling, cut open a hole for the floor drain, approx. 60 mm smaller than the drain's diameter. Finish with a compatible clamp ring.

Fix floor tiles with Kiilto Saneerauslaasti, Superfix DF, Kerapid, Lightfix, HighFlex S2 DF. Allow to dry properly and grout the tiles with Kiilto Lattiasaumalaasti. Seal vertical and horizontal corners as well as inlets with Kiilto Saniteettisilikoni.

Spraying:
Spray two coats, one coat at a time. Spraying can be done in one go; no drying between the layers is needed, but ensure that the required membrane thickness (stated in the certificate) is reached.
