LG-104 Seal-It

Seal-It! Deep Penetrating Sealer (TS-104) permanently seals and densifies concrete, plaster and Gunnite. Moreover, it increases the bonding power of paint by up to 300% making it a compelling choice. Withstands hydrostatic pressure up to an amazing 60 PSI! Not a coating; it does not leave a finish behind because 100% is absorbed by porous surfaces. Creates a permanent water barrier increasing compressive and flexural strength in the process. It contains a catalyst that seeks out and reacts with moisture, free alkali (lime), calcium hydroxides and other particles present within the matrix fusing them together creating an impenetrable silica. The entire surface penetrated is impregnated and converted turning the entire structure into a solid mass preventing the movement of moisture permanently. It is important to use the TS-695 Etching Cleaner after applying Seat-It.

Seal-It! is a chemically reactive deep penetrating sealant that works internally within the concrete matrix; not as a surface sealant. It does not alter or affect the color or texture of the surface treated. It retards penetration of grease, oils, wax and acids. Cures new concrete uniformly, resists hair checking, retards pitting, dusting, rutting and displaces grease and oil. Densifies and hardens surfaces extending the life of treated surfaces by reducing or eliminating wear due to abrasion, freeze-thaw and salt attack.

Not intended for use on non-porous surfaces. Acceptable for use on Portland cement, concrete, gunnite, stucco, plaster, porous tile, shotcrete and mortar. Point of refusal is typically reached at three applications. Treats 150—200 square feet per gallon, per application. Apply by Sure-Flow or pump-jug sprayer. It is zero VOC, nontoxic and not HAZMAT.  Available in one gallon and five gallon containers.

Application Instructions

This information has been prepared for use with Seal-It! Deep Penetrating Sealer on properly prepared surfaces. Seal-it! is zero VOC, nontoxic  and it is not HAZMAT. It not a coating, it is a deep penetrating sealant, 100% of which is intended to penetrate the surface leaving no residue behind. It works by acting as a catalyst to combine components within the concrete matrix to create an impenetrable barrier to moisture and vapor transmission. It is acceptable for use on Portland cement, concrete, stucco, porous tile, Gunnite, Shotcrete and mortar. It does not alter or affect the color or texture of the surface treated. It retards the penetration of grease, oils, wax and acids, cures new concrete uniformly, resists hair checking, retards pitting, dusting, rutting and displaces grease and oil. New concrete must be allowed to cure 28 days or more before application. To avoid penetration and curing issues we recommend establishing the accurate amount of vapor transmission and pH level prior to application. Prior to the application of paint or coating products porous substrates must test at no more than 4LBS hydrostatic pressure with pH under 9. We recommend utilizing the VaporGuage calcium chloride moisture test, or the equivalent. Never apply in hot direct sunlight or when rain is forecast within 48 hours. Under most circumstances allow 24-48 hours between coats.

Surfaces testing above 4 lbs hydrostatic pressure should be retested after the application of Seal-It! using the VaporGuage Test Kit to ensure hydrostatic pressure has been reduced to acceptable levels. Additional applications of Seal-it! may be required to achieve desired results.

1. PREP-WORK: Best results will be achieved by sanding, grinding, blasting or similarly abrading the surface, which opens the pores supporting penetration. All repairs should be completed and allowed to cure prior to sanding, blasting, grinding or the application of Seal-it! Use the VaporGuage calcium chloride moisture test kit, or similar method, to establish the level of vapor transmission and pH before application.

2. CLEAN: All applications will require the complete removal of all sealants, paint or coatings, grease, oil, glue, contaminates and similar substances that may prevent proper penetration or proper curing. Triple Strength Paint Stripper (TS-646) may be used to remove paint and coatings. Mastic remover will remove glue and industrial degreaser, TSP and similar products will remove grease and oil. Seriously contaminated areas may require resurfacing. Power-wash as needed to remove dirt and grime. Recommend using TS-695 Etching Cleaner or muriatic acid to open the pores. Muriatic acid should be properly neutralized. TS-695 Etching Cleaner or muriatic acid should be used after the Seal-It and before applying paint.

3. APPLY SEAL-IT!: Lightly pre-wet surfaces which promote penetration. Most applications are by hand pump sprayer, however brush and roller coat applications are acceptable. Apply evenly avoiding puddling. Under ideal circumstances allow 24-48 hours between coats and 72 hours to cure.  

4. REPEAT APPLICATIONS: Best results will be achieved by three applications of Seal-It!. Let stand 24-48 hours between applications. Apply evenly avoiding puddling. Never apply paint or coating products before Seal-It! has been allowed to cure fully.
