Flexible Epoxy Membrane
0.0 (0)
Sikafloor®-265 is a two component, high solids and elastomeric epoxy for use as a flexible membrane. Sikafloor®-265 is a true elastomer for use as a seamless, waterproofing membrane for floor and wall applications. This unique polymer system maximizes flexibility and elongation to provide excellent crack bridging capabilities. Applied as a clear or field pigmented with Sikafloor Epoxy Color Additive-N. When properly applied, is certified to ANSI 118.10 for waterproofing membrane at applied thickness of 40 mils.

MIXING
Clear Resin
Premix each component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes using a low speed drill (300 - 450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce any air bubbles while mixing.
Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.
Field Pigmented
Premix each component separately. If color is desired, the appropriate Sikafloor Epoxy Color Additive-N is added to Component A at a rate of 1 quart per 4 mixed gallons (i.e. Components A+B) for all colors except bright colors like White, Safety Yellow or Tile Red which require 2 quarts per 4 mixed gallons (i.e. Components A+B).
Mix Component A and Sikafloor Epoxy Color Additive for 2 minutes or until a uniform color is achieved with a low speed drill (300 - 450 rpm) and Exomixer or Jiffy type paddle suited to the volume. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for additional 2 minutes. Be careful not to introduce any air bubbles while mixing.
Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
APPLICATION
As Primer
Apply primer by squeegee at the rate of 160 - 200 ft2 / US gal (3.4 – 4.9 m2 / L) at 8 – 10 mils (0.20 – 0.25 mm) wet film thickness (w.f.t.) and back roll with pressure after 15 minutes. Coverage will vary depending on the porosity of the prepared substrate. Product has a limited Pot Life, see Typical Data.
Do not apply by dipping roller into mixing container. Pour a bead of product in the form of a ribbon on the surface to be coated, then spread with squeegee and back roll. Ensure that the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
If necessary, apply an additional coat to ensure the coating is pore-free and pinhole-free and provides uniform and complete coverage over the entire concrete substrate.
As Sealer/Membrane
Sikafloor®-265 is applied with a 10 - 20 mils (0.25 - 0.50 mm) notched squeegee over a smooth surface. Back rolling is typically done with an 18 inch (455 mm) wide 3/8 inch (10 mm) short nap, solvent-resistant roller cover. Back roll the Sikafloor®-265 only to level the squeegee applied material; over-rolling and late back rolling may cause bubbling and leave roller marks. Product has a limited Pot Life, see Typical Data.
Do not apply by dipping roller into mixing container. Pour a bead of product in the form of a ribbon on the surface to be coated, then spread with squeegee and back roll.
As Broadcast Layer
Sikafloor®-265 is poured in the form of a ribbon on the surface to be coated and spread evenly with a 30 mils (0.75 mm) notched squeegee over a smooth surface. The back rolling its typically done with an 18 inch (454 mm) wide short nap, 3/8-inch (10mm), solvent-resistant roller cover. After the materials has leveled out (approx. 10 - 15 min after placing the material), start broadcasting quartz sand to full rejection. As Wall Coating: Apply in accordance with Sikagard Wall Systems technical system sheet.
