Product Description

Crystal Lok® is a water based concrete penetrating sealer, formulated to waterproof, damp proof, seal and keep the natural appearance and profile of Portland cement based concrete, concrete blocks, mortar, gunnite, slabs, floors, subsurface vaults or basements, walls, roofs, pillars, pipe, sculpture, architectural structures, statuary and decorations. Apply to concrete with stone, steel or poly fiber aggregate, free of other chemistry including coatings, sealers, cleaners or contaminates, as specified in the paragraph "Standards" below.

Crystal Lok® penetrates concrete, crystallizes within pores, voids and hairline cracks to create waterproof concrete to zero permeability, under any pressure with no leakage at least to 75 pounds per square inch in ASTM grades of structural concrete and concrete products, from a single application of 300 square feet per gallon.

Crystal Lok® protects against water seepage, freeze-thaw spalling, efflorescence, absorption of liquids including water, oils, acids, ores, chloride ion - salt - intrusion; attack by alcohols, petroleum fuels, and other sources of damage where the seepage is not caused by cracking or other structural flaws. Crystal Lok® is fast drying, requires no maintenance, allows for routine and extreme maintenance of the surface including sandblasting and blast track abrading after application, if surface treatments require. Crystal Lok® prevents or aids in abatement of dampness odors caused by mildew bacteria in ground water or flood water or fungal growth colonizing concrete surfaces .
Go to Chemical Defense List

Basic Use: A single application of Crystal Lok® creates zero permeability in Portland cement based concrete of any shape, and for immersion at least to depths of 175 feet, defends concrete from ground water or other liquids, and from surface penetration of damaging liquids and freeze-thaw surface damage.

Packaging: Five and Fifty five.

Surface Preparation: Remove dirt, grease, oil, old paint, form release agents and other deposits for a residue free surface. Surface may be etched or blast tracked or sand blasted prior to application. Surface must be able to absorb water.

Spreading Rate: 300 (5 sq. meters/ltr) - 200 square feet per gallon. Coverage rate depends on the surface porosity of the concrete. 300 sq. ft = zero permeability on ASTM concrete.

Apply with clean hand pump garden sprayer, airless paint spray equipment, roller, or brush.

Airless spray tip orifice .017 - .027 inch with .019 inch optimal. Clean equipment with soap and water after use.

Application Guide

Application Conditions: Apply at 35ºF and rising and below 110ºF (6º-39ºC). Mix well. Agitate while applying. Crystal Lok® may be applied to dry or damp concrete, but not onto puddles or flowing water. Wet down hot concrete to cool to allow absorption before evaporating, and to break surface tension. May be applied to any age concrete. New concrete apply after forms are removed and surface can be walked on - wait 28 days for full cure.

Protect any glass, brass or aluminum surfaces as permanent etching will occur on contact. Not suitable for clay brick or other clay based products as it is not designed for them. Do not apply onto painted surface as it will soften paint.

Application Method: Brush, roll or spray undiluted Crystal Lok®. May use garden type sprayer as pressure is not critical. For large areas spray or roller is recommended. Spray in a fan pattern with overlap. Apply at rates of 300 - 200 square feet per gallon, total. May apply this amount in several lighter passes. Second pass after 15-30 minutes. A third pass may be applied up to 3 days following the second. For floors, roofs, may apply to a total of 150 square feet per gallon as the total of three applications if preferred.

Avoid ponding or puddles if a residue free surface is preferred. Puddles will result in white crystalline formations tightly adherent to the surface that requires grinding to remove - the same structure Crystal Lok® creates within the concrete. Remove puddles by sweeping, air blast or hose surface with water. Water rinse after absorption does not interfere with effectiveness.

After applying Crystal Lok® normal concrete maintenance or surface abrasion may be undertaken without altering the permeability.

Topcoat: Apply topcoats to manufacturers specifications. May be top coated with high alkaline tolerant coating. For coatings requiring neutral pH substrate rinse with mineral salts remover, water, or acid etch, to manufacturers specification to obtain recommended pH or surface characteristics.

LIMITATIONS


•Do Not store, mix or apply in Aluminum containers.
•Requires structural Portland cement concrete, mortar.
•Not suitable for clay brick or other clay based products.
•Do not puddle or allow Crystal Lok® to dry on the surface if residue-free surface is required. Remove unabsorbed excess immediately by spreading with air, wiping up with cloth or sponge mop, squeegee or rinse off. Excessive Crystal Lok® from puddles leaves hard white CSH crystalline deposits requiring blasting, grinding or acid etch to remove. Same crystallization as inside the concrete. May rinse with water as soon as product is absorbed into concrete.
•Will permanently etch glass, aluminum, porcelain, enamel, plastic on contact. Protect from exposure to spray or run-off.
•Do not apply over painted surfaces. Softens paint on contact.
•If concrete will not absorb water, it will not absorb Crystal Lok® Test absorption by sprinkling water on surfaces.
•Will not penetrate if concrete has had prior treatment with similar materials. Test sample area for suitability.
•Do not apply below 38° F and above 110° F. Use water to break surface tension on hot surfaces.
•Not compatible with Class C fly ash formulation as that is considered to be self cementitious and pozzalanic. Class F fly ash & silica fume are usually OK. Test first.
• CRYSTAL LOK LLC. does not warrantee application of topcoats over Crystal Lok® - treated surface.
