5 Effective Solutions for Efflorescence

Plumberparramatta efflor

Efflorescence is a marking on the floors or walls that is white in colour and usually appears chalky and powdery. This is caused by crystalline deposits along the masonry. They are usually brought by winter rains but can also be present during warm weathers. The main damage that efflorescence bring to a structure or plumbing system only extends to its aesthetic fa├žade. While extremely unpleasant to the eyes, efflorescence does not harm any facto in the plumbing system nor does is interfere with its activities and functions. They are merely patches on the surface of the cement that are considered unpleasant to some.

Here is additional information about efflorescence that you might find interesting:

The Causes

1. Groundwater

Crystalline deposits that cause efflorescence are also present in groundwater which is the reason why they might appear at random places in your home. They get carried by water that circulates underneath the foundation of the building. Whenever the body that carries the water travels upward and precipitates, the efflorescence is left behind forming patched and markings.

2. Humidity Rate

As the water evaporates, it leaves behind the salt that it was carrying around. During the winter, efflorescence does not make it to the surface since the humidity rate is slow. However, during the summer when there is a high humidity rate, water evaporates faster leaving the efflorescence on the surface of the concrete.

The Solution

1. Foot Traffic

Occasional foot falls or foot traffic can remove the markings gradually. Letting people walk all over the white blotches will help you remove them without having to spend money on tools or cleaners to help you with the job.

2. Rain

Given that the efflorescence is made up of salt deposits that are left after the untreated water evaporated into the air, they can be removed by exposing the area to rain. The impact of the cascading water can effortlessly remove the stain.

3. Natural-Coloured Concrete

Over the course of designing your home, consider having light-colored finishes. The light hue will help greatly in concealing any blotches of efflorescence in the future. This way, even though the size will exceed your expectations or if there are numerous patches all over the floor, you will still be able to hide the white markings and not be too concerned about the aesthetic disturbance it creates.

4. Brushing

If you are very concerned about the damaged that the markings have imposed to your floorings, you can proceed to brush it off. Dilute your laundry detergent with water and pour the mixture over the markings. Brush away any evidence of efflorescence and proceed to rinse the detergent mixture off the concrete bearing in mind that any leftover residue will come back as another batch of efflorescence.

5. Chemical Cleaners

This method may be effective but it does not come without a consequence. Soak the surface with water and apply the acids or cleaners you prefer and follow the application directions that the manufacturer provided. Note that acids and chemical-based cleaners can open concrete pores and discolour the surface of your flooring. If you are adamant in using chemicals, test the item on a small portion of the slab first before applying in large quantities to observe its effect on the surface.
