Why Paint the Outside Walls ?

 

In the main bricks give a very attractive as well as protective finish to a home and need no on-going maintenace when sound,so ideally should never really be painted as this will start a continuous maintenance cycle.

Bricks are generally painted to keep water out.  When a property has had bricks painted it is normally a clear indication that the bricks have lost their integrity and begun allowing excessive moisture in.

If the wrong type of paint is used this “seals” up the building and causes the interior to “sweat”.

Mould growth

usually follows.

Once a property has been painted it will continually need redecoration every 2 – 3 years.  The more times it is painted the more the “sweating” problem can be worsened and becomes evident in bubbling and peeling paint.

Repeated Re-painting Can Seal Walls  

peeling masonry paintWhen it comes to

external masonry painting

it is virtually unheard of for the painter to fully remove all the previous paint,wire brush the wall down then apply a

primer coat

before applying the final masonry paint. At best they may just remove any loose or flaking paint before brushing or spraying on the latest coat.

Unfortunately,this adding of layer upon layer as the years pass, greatly reduces the ability of the wall to breathe and can lead to interstitial damp ie moisture trapped in the wall that can’t get through the paint to evaporate to the outside. This happens because modern

masonry paints

have minute breather holes within the paint film and these must be kept open to allow the wall to breathe and can become clogged by overlaying extra paint layers.

 

Bricks Need  Breathable Masonry Paints

paint exterior brickwork

or stonework the masonry paint or wall coating needs to be able to firstly adhere strongly and bond to the wall and secondly be able to let the wall breathe from the inside to outside whilst preventing

peeling and flaking paint

caused by water entering the wall.

Preparation of the wall is crucial as all loose and unsound paint or mortar must be removed from the wall along with any algae or mould before the new paint coating is applied.

Of particular neglect in preparing a house for painting is the condition of the mortar pointing between the bricks. In fact this is often the area in which damp penetration can occur so it is crucial that the mortar joints are properly pointed and if possible the pointing should be flush with the brick faces to give an even finish.

Wethertex has its own advanced and uniquely formulated masonry paint coating that self primes so it can go over solid existing paint and still form an unbreakable bond whilst also being

microporous

enough to allow moisture to escape but prevent water from entering.
