Sikafloor® MultiFlex PB-55 UV always has to be sealed with Sikafloor®-359 N. Refer to the chemical resistance of Sikafloor®-359 N.

+10 °C min. / +30 °C max.

+10 °C min. / +30 °C max.

80 % max.

The substrate and uncured floor products must be at least +3 °C above dew point to reduce the risk of condensation or surface damage of the floor finish.

+10 °C min. / +30 °C max.

≤4 % parts by weight
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).

Times are approximate and will be affected by changing ambient and substrate conditions

(1) Depends on roughness depth Rz (all values at +23 °C)

• Rz = 0,0: ~1,9 kg/m² 
• Rz = 0,5: ~2,5 kg/m²
• Rz = 1,0: ~3 kg/m²

(2) Depends on temperature

• +23 °C: Filling 1:0,5 with quartz sand 0,1–0,3 mm
• < +15 °C: Filling 1:0,4 with quartz sand 0,1–0,3 mm

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

NB: A second coat of primer maybe required to ensure a pore free and sealed surface

The substate should meet the minimum requirments of 25mpa compressive and 1.5mpa minimum pull of value: Please refer to the Sika Work Method Statement: Evaluation and Preparation of Surfaces for Flooring Systems

The concrete surface should be suitably prepared by Captive Shot Blasting or Diamond Grinding to acheive a CSP 3 then vacum cleaned to remove all dust and surface contaminates, all curing agents should be fully removed, Please refer to the Sika Work Method Statement: Evaluation and Preparation of Surfaces for Flooring Systems.

Reglets should be cut next to drains and live edge terminations to ensure a secure and waterproof transition.

Please refer to the Sika Work Method Statment: Mixing & Application of Flooring Systems: Please refer to individual Product Data Sheets for further information.

All products should be mixed in accordance with the Sika Work Method Statement: Mixing & Application of Flooring Systems

1.CombiFlex: Installation of Sika CombiFlex System if required at parapets, walls and expansion joints as required by the project. Please seek advise form the Sika Techncial Department to ensure the corret system is used for your specific application.

2. Patching: Static cracks and surface defects should be repaired using SikaDur 33 Epoxy paste or other epoxy repair method subject to size and rectification required, all repairs should be finished smooth and flush with the concrete substrate: Please consult the Sika Technical Department for further details or informaiton.

3. Priming: An evaluation should be conducted to determine if double priming maybe required, once priming is completed the surface should be completely sealed with no presence of pinholes to ensure substrate outgassing does not continue in later applications. For ramps and falls extra broadcast material should be applied to slow the rate of flow for when the membrane is to be applied

Single Primer Applications: Mix and apply the Sikafloor 160 or 161 via a squeegee at the required thickness and back roll once applied to make even, Fill all pin holes and uneven surfaces,  while still wet lightly broadcast the required washed and dried sand aggregate. Do not add thinners.

Double Primer Applications:

1st Application: Mix and apply Sikafloor 160 via a squeegee at the required thickness and back roll once applied to make even. Fill all pin holes and uneven surfaces.

2nd Application: Mix and apply the Sikafloor 161, Sikafloor filler can be added to the Sikalfoor 161 at various addition rates to create a "Scratch Coat" mix to aid in filling of pinholes and uneven surfaces: Apply the Sikafloor 161 by a squeegee at the required thickness and back roll once applied to make even, ensure to fill all pin holes and uneven surfaces, while still wet lightly broadcast the required washed and dried aggregate. Do not add thinners.

4. Membrane: Mix the Sikafloor 376 and apply with a V-Notch Squeegee to a minimum coverage of 1.5mm, a hand trowl can be used for edge, joint and drain, terminations, once installed a Spike Roller or 10-12mm Nap paint roller should be used to even out the applied Sikafloor 376 to remove sgueegee marks and trowel edges to ensure a consistent and even coverage.

5. Wearing Course: Mix the Full kit of Sikafloor 377 for 1 minute, then add between 7-10kg of Sikafloor filler and mix for a further 2 minutes (Addition rate is adjustable, subject to site and ambient conditions) apply with a V-Notch Squeegee to a minimum coverage of 1.5mm, a hand trowl can be used for edge, joint and drain, terminations, once installed a Spike Roller or 10-12mm Nap paint roller should be used to even out the applied Sikafloor 377 to remove sgueegee marks and trowel edges to ensure a consistent and even coverage. Using Rounded Tip Spike Shoes, Broadcast the Sikafloor 377 with the Selected aggregate to refusal, there should be no glossy or bald spots.

Top Coats: NB: For best results the the application of top coats should be completed in 2 x applications, a sealer coat and final finish top coat, Sikafloor 377 Tinted can be used for the first sealer coat in order to keep costs down, with the final finish top coat of Sikafloor 359N required to provide UV stability.

4: Sealer Coat: After sweeping and vacuming to remove excess sand, Mix the Sikafloor 377 with the addition of 2 x 1.15kg Color Packs in the required color, Do not add fillers to the sealer coat. Apply with a medium rubber sgueegee, working accross the face, back and forth in single smooth motions, Using a 10- 12mm Nap Painters roller, back roll the floor to remove any drips and heavy applied matieral, once material has been evened out, use the un-loaded roller to "lay off the floor" taking care to lay the floor off in a single direction, working accross the flooring edge from end to end in a single smooth motion. Failure to lay the floor off in an effective mannor may result in a patchy orun-even finish,
5: Final UV stabel Top Coat Mix the Sikafloor 359 and apply with a medium rubber sgueegee, working accross the face, back and forth in single smooth motions, Using a 10- 12mm Nap Painters roller, back roll the floor to remove any drips and heavy applied matieral, once material has been evened out, use the unloaded roller to "lay off the floor" taking care to lay the floor off in a single direction, working accross the flooring edge from end to end in a single smooth motion. Failure to lay the floor off in an effective mannor may result in a
patchy or un-even finish.
