Sikafloor®-305 W NA

PUR

12 months in original unopened container.

Store in dry and cool conditions at temperatures ranging between 40 and 90 °F (4 and 32°C).

Please Consult Sikafloor Technical Services.

Coverage rates are calculated based on material needed for finishing of smooth surfaces. Approximately 320 sq. ft. per gallon at 5 wet mils.

Kit coverage is approximately 653 sq. ft. at 5 mils wet.

Mixing Ratio -  4:1 by volum .

Mix Full units only.

Premix Part A resin using a drill and Jiffy blade (300 - 450 rpm). Add Part B hardener to Part A and mix with a jiffy mixer continuously for 3 minutes until a uniform mix has been achieved. To achieve a smoother surface texture and longer working time, 5 (12 oz.) to 10% (24 oz.) water by volume should be added to each resin/ hardener mix.

Following addition of the water, mix with jiffy mixer continuously for 1 minute. Wait one minute and then mix again for one minute. The quantity of water added must be the same in every mix. If the quantity is not the same, it can influence the gloss and texture of the cured film resulting in irregularity in the finished floor.

To ensure thorough mixing, pour materials into a second container following the initial mix and blend again to achieve a consistent mix. Over mixing may cause air entrainment.

This material can be applied using either a spray or roller application. Most consistent finish results are obtained through spray application. Contact Sikafloor® Technical Service for more information regarding spraying this product.

Prior to application confirm relative air humidity and dew point. Minimize air movement during the topcoat application to ensure that surface dry does not happen prior to release of any bubbles or entrapped air. Ensure that sufficient air movement is restored following the application in order to ensure the required curing conditions are met.

Divide the area to be coated into equal sections for the number of units to be applied to ensure the correct yield. Wet out rollers when starting application taking into consideration the amount of material the roller will absorb. The roller will absorb approx 10.5 oz. - 17.6 oz. of coating. Start coating the floor by cutting in the edges with a brush and/or small roller. Only cut in edges of an area that can be topcoated in 10 minutes, to attain minimal visibility of roller marking.

               
Work quickly within the potlife to pour out the material and spread at the desired coverage rate. Overworking or under-application may also result in coating pick up or glossy holidays in the cured film.

IMPORTANT NOTE-- This product does not have a visible end of pot life.

It is imperative that to watch the time and temperature to ensure you are working well within the potlife. Roller Application: To minimize roller marking, the material must be poured onto the floor then spread with a 3/8” nap roller in the pouring direction with the bead. The material should then be cross rolled covering a width of approximately 4 feet and a depth of approximately 5 feet.

Do not overlap more than 2” onto the prior pass. Porous areas where the surface of the self leveling layer is “opened” by sanding (such as after repairs), must be pre-coated a few minutes ahead of the final roll-out to ensure wet out and minimize visibility. A seamless finish can be achieved if a “wet” edge is maintained throughout the application. Avoid late back or finish rolling.
