Sikafloor®-515
Sikafloor®-515 is a clear, two-component, solvent-free, high solids, low-viscosity, high strength, polyaspartic resin system with exceptional resistance to automotive tire marking. Typically applied as a clear glossy topcoat over solid colour and decorative multicoloured quartz or flake broadcast systems. Its low VOC content, fast cure, and UV resistance makes Sikafloor®-515 an ideal automotive garage floor finish.

Product Temperature
Condition product between 18 °C to 24 °C (65 °F to 75 °F)
Ambient Air Temperature
Minimum 4 °C (40 °F) Maximum 30 °C (86 °F)
Relative Air Humidity
Minimum 30 % Maximum 75 % (during application and curing)
Note: Low Relative Air Humidity may result in slower cure
Dew Point
Substrate must be at least 3 °C (5 °F) above the dew point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the floor finish. Be aware that the substrate temperature may be lower than the ambient temperature.
Substrate Temperature
Minimum 4 °C (40 °F) Maximum 30 °C (86 °F)
Mixing and application attempted at material, ambient and/or substrate temperature conditions less than 18 °C (65 °F) will result in a decrease in product workability and slower cure rates.
Substrate Moisture Content
Moisture content of concrete substrate must be ≤ 4 % by mass (pbw – part by weight) as measured with a Tramex®CME/CMExpert type concrete moisture meter on mechanically-prepared surface according to this product data sheet (preparation to ICRI / CSP 3 - 4). Do not apply to concrete substrate with moisture levels exceeding 4 % mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. If moisture content of concrete substrate exceeds 4 % by mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor®-1610, Sikafloor®-81 EpoCem®CA or Sikafloor®-22 NA PurCem®.
When relative humidity tests for concrete substrate are conducted per ASTM F2170 for project specific requirements, values must be ≤ 85 %. If values exceed 85 %, according to ASTM F2170, use Sikafloor®-1610, Sikafloor®-81 EpoCem®CA or Sikafloor®-22 NA PurCem®. ASTM F2170 testing is not a substitute for measuring substrate moisture content with a Tramex® CME/CMExpert type concrete moisture meter as described above.
Do not apply while ambient and substrate temperatures are rising, as pinholes may occur. Ensure there is no vapour drive at the time of application. Refer to ASTM D4263, may be used for a visual indication of vapour drive.
Pot Life
Material Temperature | Time |
10 °C (50 °F) | ~20 minutes |
20 °C (68 °F) | ~15 minutes |
30 °C (86 °F) | ~10 minutes |
Note: High humidity will shorten working times and cure rate / low humidity will length working times and cure rate.
Curing Time
Ambient & Substrate Temperature | Foot Traffic | Light Traffic | Full Cure |
20 °C (68 °F) and 50 % R.H. | ~4 hours | ~8 hours | ~5 days |
Curing times will vary according to air and substrate temperatures and relative humidity.
Freshly applied material should be protected from dampness, condensation and water for at least 72 hours.
Mechanical, chemical and physical properties will be fully achieved at full cure.
Waiting Time / Overcoating

Ambient & Substrate Temperature | Minimum | Maximum |
20 °C (68 °F) & 50 % R.H. | ~90 minutes | ~24 hours |
Consumption
Smooth Finish Coating:
Prime coat: 3.9 m2 / L to 4.9 m2 / L (160 ft2 / US gal. to 200 ft2 / US gal.) at 0.20 – 0.25 mm (8 to 10 mil) wet film thickness (w.f.t.)
Wear coat: 2.6 m2 / L to 3.3 m2 / L (105 ft2 / US gal. to 135 ft2 / US gal.) at 0.30 – 0.38 mm (12 to 15 mil) wet film thickness (w.f.t.)
Note: Actual coverage rates and material consumption will depend upon porosity and profile of substrates. Allowance must be also made for variation in film thickness or number of coats required to achieve complete coverage of surfaces. Test sections are recommended to establish correct coverage.
MIXING
Mixing Ratio - A:B = 3:2 by volume.
Do not hand mix Sikafloor® materials. Mechanically mix only.
Premix each Component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components at low speed (300 – 450 rpm) for at least three (3) minutes with a drill fitted with an 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.
Do not mix more material than can be applied within the working time limits at actual field temperature.
APPLICATION
As a Clear Topcoat for a Broadcast Quartz or Flake Systems:
Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness of 0.25 – 0.38 mm (10 – 15 mil) 2.6 – 3.9 m2/L (107 – 160 ft2/US gal.). If required, repeat this procedure for a second coat.
As a Stand-alone Double Broadcast Quick Cure Decorative Quartz and Flake System:
Step 1: Primer - Apply neat coat of Sikafloor®-515 on a prepared substrate as a primer using a squeegee and back roll to a uniform coverage without ponding at 0.20 – 0.25 mm (8 – 10 mil) 3.9 – 4.9 m2/L (160 – 200 ft2/US gal.).
Note: When using Sikafloor®-515 as primer extra precaution has to be taken on the substrate preparation and moisture content, see product limitations for further details.
Step 2: First Broadcast Application - Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness of 0.25 – 0.38 mm (10 – 15 mil) 2.6 – 3.9 m2/L (107 – 160 ft2/US gal.). Broadcast pre-blended decorative flakes or coloured quartz aggregates into the binder to saturation. Broadcast in a manner so that the flakes or coloured quartz aggregates fall vertically into the binder. Broadcast to rejection. Ensure that broadcast flakes / aggregates cover entire surface. Allow broadcast system to cure sufficiently to be able to resist foot traffic without damaging the surface. Remove excess flakes / aggregates from the surface by sweeping up and vacuuming, until surface is free of all loose particles and dust.
Step 3: Second Broadcast Application - Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness of 0.25 – 0.38 mm (10 – 15 mil) 2.6 – 3.9 m2/L (107 – 160 ft2/US gal.). Broadcast pre-blended decorative flakes or coloured quartz aggregates into the binder to saturation. Broadcast in a manner so that aggregates fall vertically into the binder. Broadcast to rejection. Ensure that broadcast flakes / aggregates cover entire surface. Allow broadcast system to cure sufficiently to be able to resist foot traffic without damaging the surface. Remove excess flakes / aggregates from the surface by sweeping up and vacuuming, until surface is free of all loose particles and dust.
Step 4: Finish Coat - Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness 0.25 – 0.38 mm (10 – 15 mil) 2.6 – 3.9 m2/L (107 – 160 ft2/US gal.). When required, repeat this procedure for a second coat.
Critical Recoat / Overcoat Time
It is important to apply subsequent coats of this and other products within 6 to 24 hours (under normal curing conditions). If this coating is allowed to cure longer than the 24 hours before subsequent recoats, light sanding, vacuum cleaning and solvent wiping will be necessary. The floor surface should be sanded / abraded to the effect that a uniform dullness is achieved. There should be no gloss present on the floor after vacuuming and before applying the next coat.
CLEAN UP
Clean all tools and equipment immediately after use with Sika® Urethane Thinner and Cleaner. Once hardened, the product can only be removed mechanically.
