The Problem

Efflorescence is everywhere! It occurs when moisture in concrete and masonry migrates to the surface and carries salt minerals that react with air to create calcium carbonate. It is typically manifested as an unsightly, white chalky deposit on the surface. And it can be difficult to remove. Very difficult.

The Cure

If efflorescence is the dandruff of concrete then NewLook's EffLock is the Selsun Blue™ you need to prevent it! Permanently.

EffLock is a revolutionary product system that prevents and completely eliminates both primary and secondary efflorescence in concrete and masonry mixtures. Guaranteed. The water-based, eco-friendly formula permanently reacts with and binds concrete chemical impurities at the nano-molecular level to prevent the leaching of efflorescent salt, resulting in enhanced concrete performance.

Features & Benefits

  • Cures & stops efflorescence. Permanently.
  • Improves density & green cure strength
  • Stabilizes & brightens integral color
  • Revolutionary water-based nano-fusion technology
  • Works with pre-cast, brick, block, pavers, stucco & more!
​"You mean to tell me you just mix this in [our concrete mixture] and we won't ever see that [efflorescence]? Ever?...Now that's something I've gotta get in on."

What Makes EffLock So Darn Innovative?

No other admixture is guaranteed* to completely and permanently prevent efflorescence. Unlike silane or silicone based products, EffLock’s nano-fusion chemistry reacts with and binds sodium chloride deposits and other impurities of concrete mixtures. The reaction efficiently converts them into non-sodium chemicals and other harmless matter.

The nanotechnology of EffLock’s chemistry is 100,000 times smaller than even the smallest cement particle. This allows it to literally pass through cement minerals or (hollow) sand and become part of the cement or sand with which it reacts. While other products try to minimize water intrusion, EffLock uses the presence of water to its advantage.

Other products react with oxygen. EffLock reacts when hydrogen is present, meaning it needs water to react; it stops reacting when the concrete mixture dries out. But EffLock will continue to react each time the concrete gets wet. This prevents the formation of efflorescence for the life of the concrete. But EffLock’s efficient reaction during hydration allows treated concrete to retain moisture longer, which improves the initial curing process and enhances the green strength of concrete.

A more efficient reaction during the curing process also helps brighten integral colorants because there are fewer chemical impurities present that would normally dull the finish. It reduces the amount of integral color pigment needed, which means greater value to concrete professionals.

EffLock also improves the performance of densifiers and penetrating sealers. It binds contaminants and other salt-based minerals that can inhibit penetrating sealers’ ability to absorb and react. When the excess salt is bound within the slab and more free lime is present, penetrating sealers will penetrate deeper and react more efficiently.

The overall quality of concrete is tremendously improved when treated with EffLock. The cosmetic appearance is improved as the concrete cures properly, resulting in a more uniform finish. Fewer air pockets and pinholes appear during the finishing process. 

EffLock can be used with all cement types and ingredients, including lime, calcium, alpha and beta gypsum, fly ash, volcanic ash and hydraulic cement. Cure and seal products may still be used on EffLock-treated concrete. Other admixtures may also be included in the cement mix. However, EffLock should be added first and mixed with water before other admixtures are introduced to the mixture. This allows EffLock to react properly.

*Note: EffLock Admixtures MUST be mixed exactly according to instructions to produced desired results.
