technical product info

technical product info a highly-engineered terrazzo mix of natural stone aggregates, sand and cement; hand-cast to create a modern artisan surface that is truly one-of-a-kind. pacifica can be fabricated by a quality stone fabricator to suit design needs, similar to traditional stone slabs. highly durable, heat and scratch resistant and ideal for indoor and outdoor applications like countertops, islands, vanities, tables and bbq’s.

technical product info

1. the material slabs are through-body concrete terrazzo. slab edges are supplied unfinished / raw and require fabrication. slabs feature aggregate concentration to the finished surface compared to the underside. slab surface is factory polished but requires finishing and sealing post fabrication. the underside of the slab is unfinished / raw. our slabs are hand-cast concrete terrazzo and are not fully calibrated. slabs are not reinforced. a stone fabricator is required for fabrication using the same tooling ma- chinery as natural stone. slabs must be continually braced to avoid bowing. variation in aggregate, density and tonality is expected. 2. receiving your order slabs must be inspected upon delivery. any damage recorded and reported to the manufacturer immediately. set aside any slabs that are cracked, damaged or have any quality concerns and do not fabricate. remember to brace even with a pending claim. store slabs indoors, covered, protected and braced. slabs must remain braced on original a-frame as received until fabrication. do not store slabs unsupported in slab racks. brace slabs 20” from each end or sandwiched between slabs of granite. slabs should remain properly braced until installation. if stored improperly, slab bowing can occur.

shop drawing or submittals should include review of slabs for tonality and seaming. measure slab bow with spacers and an uninfluenced level across the center. a measurement greater than ⅛” from level to top surface may require slab to be relaxed. slabs can be relaxed with a simple rewetting process. re-wetting process: -

- -

lay moving blankets onto the floor or table and fully saturate blankets with water. lay slab down carefully face-up and build-up blanket if the slab center is not in contact with a blanket. saturate the slab with constant water for 5-10 min. ensuring the top and bottom are wet completely. leave the slab to sit, uncovered, allowing the surface to dry first while the bottom remains wet to relax the bow. measure flatness again in a couple of hours and repeat steps as needed.

- -

3. fabrication slabs should be fabricated by a stone fabricator using natural stone tooling. handle slabs carefully using vacuum lift or slab lifters. ensure slabs are returned to proper bracing throughout the duration of fabrication. set slabs down on a tilted table to avoid stress. bridge-saw cut with continuous rim diamond blade or water jet-ample water and slow speed. slab edges should be mitered. minor surface pinholes or edge chips can be filled with color matched epoxy. back-rod any sections of slab less than 6” in width i.e. sink rail.

4. installation slabs must be fully supported with 3/4” plywood fixed to cabinets or support structure. slabs must be installed on a sound substrate. plywood alone is not a support, the plywood must also be supported by the structure. consider additional support methods if plywood flexes when pressed. ensure plywood substrate is clean and free of debris. plywood substrate should span no more than 24” between cabinets or supports. slab spans/cantilevers greater than 6” must be fully supported by substrate. slabs should be fully bonded to substrate with adhesive bedding, epoxy or silicone. shims may be needed to achieve a level installation. shims should not be a primary source of suppor, ensure adhesive bond supports slab. seam with flexible caulk or epoxy. acetone ok for joint detail cleanup. ensure slabs are cleaned thoroughly and protected especially prior to sealing. 5. clean + seal in preparation for sealing ensure slabs are cleaned thoroughly. remove any residues from the surface in- cluding adhesive or epoxy from fabrication and installation. slabs should be wet-scrubbed using an htc twister white pad. cut a 5” circle out of the white htc twister pad and attach to a low speed polisher or ahand-held orbital sander. wet-scrub using clean water. protect cabinetry and surrounding finishes. a slurry should develop. remove slurry and rinse with clean water and allow to dry. apply l.s.c.s. densifier preseal wiping on

evenly by hand using a l.s.c.s. densifier preseal-soaked microfiber towel. l.s.c.s. densifier preseal should be dry-to-the- touch then apply 3 coats of prosoco polishguard finish-seal. apply prosoco polishguard by wiping on evenly in a very light coat with a prosoco polishguard-soaked microfiber towel by hand. do not spray or use a sponge or alternate applicator and avoid over-application of prosoco polishguard finish-seal. allow each coat of polishguard to be dry-to-the-touch before repeating the next thin coat. once cured (approx. 7 days) apply cc conditioner. allow 7 days before initial use of counters. 6. care + maintenance wipe up spills as they occur. give immediate attention to acidic liquids like lemon juice. acids can etch. wipe regularly with clean warm water and neutral (non-acidic) detergent. apply cc concrete conditioner routinely. water. scrub with scotch brite dish sponge and wipe clean. for deeper stains, allow the cleanser to sit before wiping clean. sealer can be reapplied to a specific spot if aggressive cleaning removes sealer. should water or liquid no longer bead-up on the surface, or counters are marking more easily or finish sheen has worn down, the clean + seal process can be repeated spot clean stubborn stains with bar keepers friend cleanser powder and prosoco polishguard sealer, htc twister white pad, l.s.c.s. densifier preseal, cc conditioner are all available for purchase through con- crete collaborative. bar keepers friend cleaner, scotch brite dish sponge, neutral cleaners, microfiber towels all readily available products for care + maintenance.

7. future re-finishing should water or liquid no longer bead-up on the surface, or counters are marking more easily or finish sheen has worn down, the clean + seal process can be repeated. if you have any questions please contact our technical team: tech@concrete-collaborative.com - -
