Kretetek Ghostshield Sila-Tek 3500 is an advanced, industrial strength, deep penetrating concrete sealer and densifier. Kretetek's unique formula incorporates leading molecular nanotechnology to penetrate 2-4 inches. The subsequent chemical reaction elicited from KreteTek's formula fills the pores and capillaries with an impenetrable crystallization. The secret to effectively sealing and densifing with Sila-Tek 3500 is to have KreteTek's sealer react with as much of the free lime and calcium present within the concrete as possible. Sila-Tek 3500 is a uniquely transparent formula containing a proprietary blend of enzymes and surfactants that aide in accelerating a deeper penetrating disbursement. Thus eliciting a more effective, uniformed chemical reaction between our formula and the concrete / masonry substrate it's being applied to. Surpassing anything else on the market the Sila-Tek 3500 treats and seals from the inside out; strengthening the concrete as well as providing a seal that will not chip, flake, delaminate or breakdown with UV light exposure
