Product Information

FGS HARDENER PLUS is a water-based, VOC compliant, odorless and environmentally safe component of this process.
FGS HARDENER PLUS is applied as the last and final step to the finished concrete surface. This final step is important in order to provide long-term dustproof protection to the floor, as well as to enhance and extend the visual impact of the resultant polished finish. FGS HARDENER PLUS has been formulated to counteract the aggressive microscopic abrasive action of the abrasive smoothing, diamond grinding and polishing steps. A two-coat installation of FGS HARDENER PLUS is required to effectively protect prepared concrete floors.
FGS HARDENER PLUS has been specifically formulated to meet the unique demands of a flat, ground and polished floor - better than any other L&M product, and better than any competing product.
Treatment of a ground and polished floor with FGS HARDENER PLUS will add years to a treated concrete floor's expected service life, as well as reduce the cost of regular maintenance of that same floor. The powerful densification of a concrete floor by FGS HARDENER PLUS increases its durability by chemically and permanently transforming the comparatively soft, exposed cement paste into a hard, wear-resistant surface. This chemical process also reduces micro-pitting.
FGS HARDENER PLUS is easy to use. Work area downtime is greatly minimized and its odorless formula allows its use in employee-occupied areas without concern. The deeply penetrating chemical action leaves no film to scratch, chip, peel, discolor or otherwise deteriorate, and its presence will not alter the natural nonslip texture of the concrete floor.
Basic Use:

FGS HARDENER PLUS is required for use on floors that have been diamond ground and polished in accordance with the patented FGS PermaShine Process. Typical areas that would benefit from this process include floors subjected to medium or heavy fork lift and tow motor traffic: including those found in warehouses, distribution centers, automotive assembly plants, manufacturing plants, textile mills, coolers and freezers, food processing plants, canning factories, breweries, bakeries, meat and poultry processing plants, service garages, grocery stores, discount retail stores, hub transfer facilities, commercial buildings, and most concrete floors needing rehabilitation.
Other uses include concrete floors subjected to frequent or heavy pedestrian traffic, such as: civic centers, retail sales outlets, discount stores, restaurants, food preparation areas, sports arenas, stadiums, hospitals, airports, museums, schools and grocery stores.
