LastiSeal Brick & Concrete Sealer Instructions
Penetrating clear sealer for concrete, bricks, pavers, masonry, and porous building materials. Waterproofs, strengthens, and protects against capillary water seepage, freeze-thaw, deicing chemicals. Driveways, pool decks, patios, stairs, ramps, decks, CMU walls, chimney, restoration of historical buildings, statues or monuments, and paint primer.
Brick, pavers, poured concrete, concrete block, cinder block, limestone, adobe, sandstone, grout, mortar, porous tiles, bluestone, and other porous substrates.
Chimneys, patios, pool decks, garage floors, driveways, sidewalks, facades, historic buildings, retaining walls, basement floors and walls, fireplace faces, parking lots, decks, seawalls, and similar.
Dense stone and tiles, rock, countertops, showers, hydraulic cement,epoxy or chemically-modified grout.
- Poured Concrete: 150-250 sq. ft. per gallon.
- Concrete Blocks: 100-150 sq. ft. per gallon.
- Bricks: 150-225 sq. ft. per gallon.
- Pavers: 100-150 sq. ft. per gallon.
Substrate should be dry prior to sealer application. Brick, concrete and porous masonry may require several days to dry after heavy rain or pressure washing. Avoid rain for 24 hours after sealer application. Ambient air and surface temperatures must be above 45º and below 100º F during the application and for 24 hours after. Avoid applying to hot surfaces in direct sunlight, or in strong winds and excessive humidity. New concrete should be allowed to cure for at least 28 days.
Surfaces must be clean, bare and porous. Remove paints, sealers, curing compounds, adhesives, oil, grease, mold, efflorescence and other contaminants that might interfere with the penetration of the sealer. Hard-troweled concrete surfaces require chemical etching or mechanical abrasion to increase porosity. A sufficiently porous surface should readily absorb the sealer. Use PowerEtch Concrete Etcher & Cleaner to obtain a proper surface profile. If chemical cleaners or concrete etchers are used, be sure to throughly rinse and remove them prior to sealer application. Mask surfaces not intended to be sealed. Vacuum or blow off excessive dust and loose particles.
Recommended! Brick, concrete, and masonry surfaces vary greatly in composition and porosity. Apply LastiSeal to a small test area to confirm surface suitability, aesthetics, and ensure sealer penetration.
Apply using a hand-pump sprayer equipped with fan tip nozzle (recommended). Alternatively, a paint roller or brush can be used if spraying is not feasible. Avoid pooling or excessive rundown.
STEP 1: Agitate container thoroughly before use.
STEP 2: Spray LastiSeal uniformly to the surface, maintaining a thick glistening continuousfilm. Apply more liberally to faster-absorbing areas. Broom, roll, or brush away puddles.
STEP 3: For more porous substrate, apply a lighter second application 24+ hours after thefirst application.
TIP: To avoid over-application, spot test a second application to ensure substrate is absorbing the sealer. If uncertain about sufficient absorption, use only one application.
Rinse tools with water. Remove overspray with a wet towel or sponge before it dries. Dispose of unused material and empty containers in accordance with local regulations.
DRYING & CURING
Treated surfaces will dry to touch in 1-3 hours. Avoid foot and vehicular traffic until dry.
Store in a dry location out of direct sunlight. Do not store at temperatures above 100 °F. Avoid freezing. SHELF LIFE: 1 year from date of shipment. FINISHED APPEARANCE: Natural Look.
