Sikafloor®-158 W Fast Barrier

• Water Vapour Transmission (ASTM E96)
• Green Star (VOC-SCQMD Rule 1168)
• Negative Hydrostatic Pressure - MTC test report

2-Component, water-based, epoxy resin

Sikafloor®-158 W Fast Barrier has a shelf life of 15 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.

~1.08 kg/l (mixed)

4 grams per litre

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

+10°C min. / +30°C max.

• In-situ probe test up to 100% RH

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

Note, Mixed Sikafloor®-158 W Fast Barrier stays liquid when pot life is

over. Only mix the amount of product that will be consumed directly.

DO NOT USE mixed material after pot life has expired and product begins to thicken.

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 2hrs @ +23 °C.
Note:
Drying is dependent on temperature, air flow & relative humidity. Increased air flow will help with drying speeds in cooler temperatures.

2hrs+

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 generous coat of Sikafloor®-158 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 directly.

Very Porous Surface
On very porous or mechanically prepared surfaces a second coat is recommended.

Note:
Waiting time between coats is no sooner than 2hrs. Subsequent applications of Sikafloor Systems - Refer to relevant System Method Statement.

   
For use with Sikafloor Epoxy Systems
Sikafloor®-158 W Fast Barrier Can be used in double primer applications where required, For Self Levelling and roller Epoxy or PU flooring applications, Sikafloor ®-158 W Fast Barrier must be over coated with Sikafloor 161 Roller applied epoxy before any further applications of subsequent products can be applied Sikafloor®-158 W Fast Barrier can be re coated with Sikafloor 161 Roller applied epoxy @ 3hrs @ 23degrees C, the subsequent flooring system can then be applied.
