EFFLOCK Efflorescence protection additive

Use With all cement based products.

• Screed bedding
• Tile adhesives
• Grouts
• Brick mortars etc.

Product Description

Efflock is a high performance, water based, VOC free, liquid additive designed for the bulk impregnation of cement based building materials to protect against efflorescence and damp. By controlling water absorption, efflorescence is locked and the potential for waterproofing failure is dramatically reduced.

The hydrophobic effect of Efflock:

• Prevents capillary action that can lead to waterproofing failure.
• Repels waterborne contaminants like dirt and salt, resulting in a cleaner appearance with excellent resistance to salt attack, and concrete cancer.
• Provides fast evaporative function to inhibit moss and mould growth.
• Provides unique protection against picture framing and/or crypto florescence.

Efflock can also be used as a high performance impregnating water repellent sealer for concrete, brick and sandstone.

The Efflock Technology

The Efflock additive creates a hydrophobic molecular structure within the pores of cured concrete without filling the pores of the material. The product dramatically reduces water absorption whilst remaining permeable to allow the controlled release of any moisture. Efflock provides bulk impregnation to protect concrete throughout the entire mass, so that performance is not affected by traffic wear or movement cracks.

Why Use EFFLOCK?

• Excellent additional barrier to a waterproofing system to promote drier, healthier wet areas. Complete efflorescence protection for a tiling system – compatible with tile beds, tile adhesive and grout.
• Negates the practice of installing a secondary membrane, saving around 80% cost and faster construction.
• Protects against picture framing and crypto florescence in stone, brick and concrete. Water based, environmentally friendly, VOC free.
• Concentrated formula dilutes 100 times for convenience, minimal plastic waste and minimal transport impacts.
• Prevents absorption of damp, salt attack and frost attack.
• Invisible bulk impregnation of the entire concrete mass.
• No detrimental effect towards adhesion of paint, adhesives and other finishes.
• Good workability.
• Improves curing.
• Permeable to vapour and UV stable

Always use Type GP cement
We recommend the use of General Purpose Cement (Type GP) wherever efflorescence is a risk. Both grey and off white cement is available as Type GP cement. “Builders Cement” is classed as General Blend Cement (Type GB) and should be avoided when using hydrophobic additives generally.
The increased proportion of fly ash and/ or blast furnace slag contained in Builders Cement contributes to efflorescence.
Other additives
Please refer to the recommendations for each type of mix listed in this document.
Weather
The ideal temperature for concrete to cure is 23°C. Protect concrete from premature moisture loss with shade and damp curing. Efflock should have up to 24 hours to cure with concrete before exposure to rain.
Workability
The workability of mortar can be altered with the addition of Efflock in a mix. Please refer to the recommendations for each type of mix listed in the PDS.

Please Read PDS before use.
