Sikafloor®-158 W Fast Barrier

• Water Vapour Transmission (ASTM E96)
• CETEC Green Building Council requirement
• Negative Hydrostatic Pressure - MTC test report

2 Component water-based epoxy. 

Sikafloor®-158 W Fast Barrier has a shelf life of 24 months from the date of production, if stored properly in undamaged, original, sealed packaging.

Sikafloor®-158 W Fast Barrier should be stored in cool dry conditions at all times.

Protected from direct sunlight and keep at temperatures between +5 °C and +35 °C.

Do not allow Part A to freeze.

~1.08 kg/l (mixed)

4 grams per litre

Component A : Component B = 2:1 (by weight)

+10°C min. / +40°C max.

• In-situ probe test up to 100% RH

All testing/readings should conform with relevant AS/NZ standards

4 hours at 23°C and 50% relative humidity.
 

Over-coating with a suitable Sika® - Non-porous primer, Adhesive or a second coat of Sikafloor®-158 W Fast Barrier may be applied no sooner
than 1+hours @ +23 °C.
Note:

• Drying is dependent on temperature, air flow & relative humidity and porosity of the substrate.
• Increased air flow will help with drying speeds in cooler temperatures.

1+ hours

Consumption average is dependent on the absorbency of the substrate.

• Low speed electric drill and mixing paddle required for 18kg kit
• ~10mm nap roller

4.2kg kit:
Plug the component B upright on the component A can and wait until the component B is empty, then close the cap of the component A can. After combining component A and component B in the correct ratio, shake the can thoroughly. A minimum shaking time of 1 minute is required. Re-shake is required if the mixture appearance is still inhomogeneous.

18kg kit:
Pour 12kg part A into 6kg part B (2:1) then mix with an electric drill and paddle (Paint Mixer Type) at a low speed to reduce air entrapment. Using a paint stick or similar is not sufficient to mix the product. A mixing time of 2-3 minutes shall be observed. Mixing shall continue until a homogeneous mix has been achieved. Scrape sides and bottom of pails to ensure all contents are thoroughly mixed together. Unmixed material applied to the floor will not cure properly.

Porous Surface
Apply 1 coat of Sikafloor®-158 W Fast Barrier to the substrate using a 10mm nap roller, ensuring that a continuous coat is achieved over the entire surface (MUST produce a wet reflective appearance-CLEAR). On particularly porous sections where the initial coat is absorbed immediately, re-apply immediately. 

Note:
Waiting time between coats is no sooner than 1+hrs.

Subsequent applications of Sikafloor Systems - Refer to relevant System Method Statement.  

Clean all tools and application equipment with water immediately after use.
