Trinic LS Lockup is a single component ready to use water based lithium and siliconate based solution designed to densify and add waterproofing characteristics to cement and concrete substrates.BenefitsThe densifier reacts with the cementitious ingredients to densify and add water repellency while allowing deep penetration to chemically harden and fortify the substrate.After the chemical reaction occurs, the substrate will be more abrasion resistant and help protect the surface from wear, moisture and efflorescence while remaining breathable.Mix SuggestionsDensity & Free LimeIf your floor is dense and has enough free lime to work with, lithium silicates (Trinic LS Lockup) or colloidal silicas (Trinic CS Densifier) generally work fine. If your floor contains very little free lime (was cast with a very high pozzolan dosage) or is weak (PSI wise), or very young, you may need to look for alternatives or in many cases a combination of alternatives.Strong ConcreteDense, high strength concrete requires just a little help from surface densifiers to polish compared to problem floors. When concrete is cast with high degrees of excess water, the water evaporates out of the concrete leaving channels behind. The more excess water in the mix, the larger and more frequent the channels and the weaker the mix (less ability to hold the aggregate so the polishing machine can shave it rather than pulling it out). This is the main reason most polishing concrete contractors stay away from the residential market, less quality control with the concrete. You don’t know what you’re walking into or how much it will cost to get it polished if it will polish at all.You will need to start with the largest particle required to fill the pores and work your way smaller to fill the voids, densify, and provide a uniform plain for polishing. Sometimes this can be accomplished in one densification step; other floors will require more or different densification steps.Weak ConcreteVery weak porous concrete may require a very large particle in the form of cementitious slurry prior to any attempt at densification. The concrete may be so porous that any densifier will simply absorb into the matrix without benefit to the surface. A neat (no sand or aggregate in the mix) reactive slurry will close the very large voids. This may need to be ground off before going to the next step. The next step would be larger particle (lithium silicate) mixed with smaller particles (colloidal silica). A final step (if needed) would be colloidal silica; this would bond to any silica particles present and fill any microscopic low spots readying the concrete for finale polishing. Obviously product and machine usage will be much higher than polishing dense concrete often making this option more expensive than coating the floor with a film type product.
