Efflorescence is the formation of insoluble salts that appear as white coloured staining on tiles, concrete, brickwork and stone and is generally considered as a building defect. Technical Data. Removing Gypsum Plaster Stains The most important binding materials are cement and lime. Testing has shown that SCP treatment performs equal to or better than 28-day moist cured samples. Often efflorescence is apparent just after the structure is completed. or it simply goes right through it. Add 2 cups of vinegar and/or 2 tablespoons of dish soap/detergent. Excellent exterior durability. What is efflorescence in concrete and why does it occur? 6. What causes efflorescence on concrete floors and walls? DRYLOK Original Masonry Waterproofer may be applied on a slightly damp surface, but best results are obtained when the surface is dry, clean and free of grease, oil, form release compound, and paint. 3. When moisture and water vapor migrate to the surface of hardened concrete floors, walls, and colored concrete, it carries with it calcium hydroxide. 1. Primary efflorescence takes place immediately after concretes first exposure to environmental CO 2 that means right after production. The soluble salts dissolved by moisture are drawn to the surface through pores after the plasterwork is completed and fully dry. Concrete Laitance: Efflorescence laitance is formed when theres too much water in the concrete mix: It is the deposit on concrete surfaces caused by soluble salts in concrete. Removing Grease Stains from Concrete Procedure Code: 371001S. Use High-Quality Concrete Mix. PRIMARY EFFLORESCENCE. SCP technology is often used as a superior curing medium. Although it may be an aesthetic concern, efflorescence will not affect structural performance. Use in concrete, masonry, brick, block, mortar, pre-cast and poured-in-place concrete. Use a drill bit that is slightly smaller than the width of the screws you are using, to ensure a snug fit. Grout for use in concrete masonry construction should comply with ASTM C476, Standard Specification for Grout for Masonry (ref. Surface efflorescence on brickwork is unsightly but easily remedied. Efflorescence is the presence of salt deposits on your pavers, which gives them a white or greyish tint. Removing Efflorescence from Concrete Procedure Code: 371016S. 7. The essential process involves the dissolving of an internally held salt in water, or occasionally in another solvent. Because concrete is the most abundant construction material in the world, the beneficial environmental impact of Pozzotive in concrete is dramatic.

Tags: Concrete Curing, Concrete, Curing Blankets, Concrete Setting Posted on March 14, 2013 Efflorescence: Causes and Solutions The water, with the salt now held in solution, migrates to the surface, then evaporates, leaving a coating of the salt. Efflorescence alone does not pose a major problem, but it can be an indication of moisture intrusion, which may compromise the structural material. CLEANING. Remove dust, dirt, and any loose or broken mortar with a wire brush. Efflorescence is a deposit of soluble salts and bases, usually white in color, that sometimes appear on the surfaces of masonry or concrete construction. In chemistry, efflorescence (which means "to flower out" in French) is the migration of a salt to the surface of a porous material, where it forms a coating. It happens when moisture combines with water-soluble salts in the masonry, reaches the surface, and then evaporates. Efflorescence in concrete surface refers to the appearance of a white or grayish-tinted powder on the concrete surface. Efflorescence reduction ; Spray-Lock Concrete Protection (SCP) technology offers cost-effective protection solutions that meet the demands of todays fast-track construction process. Follow these simple steps: STEP 1 Remove the efflorescence with RadonSeal Efflorescence Cleaner. Efflorescence is a white, powdery substance that appears on masonry, such as pavers, due to salt deposits that are present in the original brick.
