Remove any efflorescence with a suitable efflorescence remover / brick cleaner in accordance with the manufacturer's instructions. Rinse the surface thoroughly with clean water. Remove all visible signs of organic growth and treat the areas with
Painted surfaces already damaged by efflorescence must NOT be repainted until the source of the moisture is identified and eliminated or blocked (by waterproofing). It may be necessary to engage the services of a qualified waterproofing specialist.
Penetrating sealers are the best defense against efflorescence. These silicone-based sealers work by penetrating the surface and reacting with free lime to form calcium silicate. It's like filling the capillaries and pores with cement to block the migration of water.
The application of DRYLOK® Wet Wall Bonding Primer will minimize the reoccurrence of efflorescence when the surface is properly treated. Patch all holes and cracks with DRYLOK® Fast Plug®.
The problem with Drylok is not price, it's performance. As we've established (and Drylok admits), Drylok isn't really a waterproofing material, it doesn't adhere to concrete, it doesn't block out moisture, and still requires more material to cover less space.
Remove any efflorescence with a suitable efflorescence remover / brick cleaner in accordance with the manufacturer's instructions. Rinse the surface thoroughly with clean water. Remove all visible signs of organic growth and treat the areas with Zinsser Mould Killer in accordance with the manufacturer's instructions.
The acidity in the vinegar helps remove the efflorescence and calcium deposits by breaking down mineral crystals. After cleaning the surface, let dry for 48-72 hours (moisture content below 25%).
Efflock. 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 dampness. By controlling water absorption, efflorescence is locked and the potential for waterproofing failure is dramatically reduced ...
To prevent efflorescence coming back or out you must prevent water going in. Applying Remedial Membranes Clear Waterproofing Membrane over the tile creates a continuous waterproofing barrier over the tiles so that water does not have access to the substrate which is key to preventing the process of efflorescence.
Efflorescence must be removed before applying a penetrating sealer.
If desired, it may be topcoated with any quality paint, but will nullify the mould and mildew protection portion of our warranty. To maintain the warranty, use Perma-White® Mould and Mildew-Proof* Interior Paint for interiors and Perma-White® Mould and Mildew-Proof* House and Trim Paint for exteriors.

In all but very extreme cases, efflorescence will stop as capillaries in the stone become blocked by crystallized salts. Once the process stops, the white deposits will eventually wear off with use and exposure.

A solution of baking soda (sodium bicarbonate) and water (Approx. 1 lb. Of baking soda per 5-gallons of water) can be used to neutralize the stain. The solution should be applied until it stops fizzing.
A stiff scrubbing brush and a dry brushing technique will remove the efflorescence. Muriatic acid can be used for efflorescence removal, but it poses risks such as discolouration and potential surface damage. Consider safer commercial solutions.
In these situations, use LastiSeal Brick & Concrete Sealer for an unbeatable 15-years of protection, or go for DryWay Water-Repellent Sealer, which is a DOT approved silane/siloxane water-repellent. Efflorescence is a very common and controllable condition.
Efflorescence appears as a result of salt being pushed to the surface of masonry. It's a painting issue that's easily overcome by the use of Zinsser Watertite®.
