PulsarCrono is a series of vivid, through-color glass mosaics by Mosaico+. Comprised of 67% post-consumer and 28% post-industrial recycled content, PulsarCrono meets the requirements set by the LEED building rating system and may be used to earn LEED MR Credits 4.1 and 4.2. In addition to its recycled content, PulsarCrono is developed with a low-energy process wherein sintered glass is ground and pressed.
Colors + Finishes
PulsarCrono is available in 10 standard colors in 4 mosaic patterns.
Standard nominal sheet size is 12"x12". Actual sheet size depends on the pattern selected and are noted as follows: Pulsar 1 (12.25"x12.25"), Pulsar 2 (12.75"x12.75"), Pulsar 3 (12.75"x12.75") and Pulsar 4 (12.5"x12.875") Tiles are ¼" thick and each varies slightly, for a handcrafted appearance.
PulsarCrono is suitable for interior and exterior walls and floors, including light-traffic commercial flooring applications.
Installation Instructions + Maintenance
Use high quality adhesive from manufacturers such as Laticrete and Mapei, following manufacturers’ recommendations, depending on conditions. For swimming pools or any wet areas the substrate should be treated with a waterproofing product. Install mosaics in temperatures varying between 41F - 86F. Additional installation instructions are as follows:
Checking the Material
Before starting, check carefully the boxes containing the sheets of PulsarCrono mosaic. Spread out the sheets on the floor, double-checking and making sure that there is enough material to complete the job.
This step is necessary to make the substrate perfectly smooth. A substrate showing differences in color damages the aesthetic quality of the finished mosaic. In case of plaster substrate, use adhesives following recommendations and proportions.The surface of plasterboard needs to be treated first with a suitable primer (ask your Stone Source Sales Consultant for recommendations.) The skim coat should dry for at least 12 hours.
In order to aid the correct positioning of the mosaic sheets, draw lines on the surface of the substrate. Lay three sheets out on the floor side by side, so that the gap between the sheets is the same as the gap between the single chips, and measure the overall width. Transfer this measurement both horizontally and vertically to the surface being covered and, using a straightedge and a level, mark out a grid. The area will now be divided into a number of squares, each corresponding to nine sheets of mosaic.
Preparing the Adhesive
Prepare the adhesive and, using the trowel, spread it over an area no larger than the one which will be occupied by the above mentioned first nine sheets. With the smooth edge of the trowel apply a thick layer, than add a second application using the notched edge. After the area is combed with the notches, the smooth side of the trowel is again used to lightly flatten the ridges. Hold the trowel at a steady angle to assure an even application and a uniform bed. A uniform amount of adhesive is especially important under mosaic tiles since their small size tends to accentuate irregularities on the setting bed and because mosaic tiles are usually thinner than regular tiles, even a small amount of excess adhesive can clog up the grout joints and create a difficult cleaning job. Trowel number 4 is recommended. The mosaic sheets can now be positioned. A white adhesive is recommended as a colored adhesive may show through the mosaic and influence the final look.
Laying and Fixing
Apply the mosaic sheets directly on adhesive. Ensure that the joint between the sheets is the same as the joint between single chips.
Ensuring the Bond
Tap the sheets with a rubber float to let the mesh sink into the adhesive.
Adjusting the Joints
Once all the sheets are fixed, and before the adhesive begins to set, adjust the distance between chips to ensure a uniform joint. This adjustment can be made by using a small trowel. Allow at least 24 hours for the final setting.
Using the small trowel, scoop the grout a little at a time onto the float and begin the application. Move the trowel diagonally across the chips, first from the bottom up and then squeezing downwards in the opposite direction, forcing the grout to fill up the joints.
Before the grout hardens, begin cleaning off the surface using a sponge with clean water. Without wringing, swab the surface of the mosaic repeatedly with a circular motion until all residual traces of grout are removed.
PulsarCrono should be cleaned with warm water and a lint free cloth (terry cloth). You may also utilize conventional, non-abrasive glass cleaners together with a lint free cloth. Glass cleaning should begin with wetting the glass surface with clean water or a mild soap solution to loosen dirt. Using a neutral, non-abrasive commercial window washing solution, uniformly apply the solution to the glass surface with a brush, sponge, or other non-abrasive applicator. All strongly alkaline caustic solutions as well as acids, especially Hydrofluoric acid, and cleaners containing fluorides are not recommended.
