Greening render :
Why and how to control it.
In the past 3 decades or so self finished renders became popular among architects. There are good reasons for this, both architectural and practical. For the designer, new finishes difficult to obtain with paint were offered. Smooth, textured, with mica sparkles or colour pebbles. They are low maintenance too. Every now and again cleaned, but never painted again. On site, no more curing time before finishing the building. It suits modern building constraints.
Yes, it's raining here Ireland...Give's me a bit of time to add another post here though so not all bad (if only it lasted the twenty mins it took to do this!)
Another great advantage to this warm wet weather?? The moss and algae love it!
I was in Ardara, Co. Donegal a couple of weeks back at a training day for applicators of the Mossgo Pro system, Michael Conway who was giving the course had put together a few pages of information and pictures and among these was a table titled Method/Product Comparison, which outlined the Pro's and Con's for both Aggressive (pressure washing, harmful chemical cleaning) and Non aggressive (Mossgo pro system).

When looking at an ageing building,
few people cast a critical eye at the state of the roof. The windows are clean,
the garden tidy and the interior spotless, but the roof is almost invariably
unkempt. Black moulds hide it's colour and moss slowly mats itself in the bonds,
so slowly that few take notice.
encroachment of grime and moss has it's effects : Beyond the architectural downgrade the fabric
of the building is at risk. Doing nothing is ultimately the expensive option.
Just a quick one on something that we are coming across a fair bit lately.
Walls, roughcast renders and pebble dash treatment.
The extensive use of rough cast renders and pebble dash on walls has
led to the development of appropriate cleaning techniques.
Coloured renders or Monochouche as it’s also known was particularly popular
during the most recent building boom here in Ireland.
Although the new build industry has all but
gone these types of plastering are appearing more and more as services such as
External Insulation continue to grow.
Just when we thought it was time to pack away the winter woollies out pops Met Eireann with a weather warning, and not just an ordinarily weather warning either, an orange status warning! This can mean only one thing Sneachta! The country grinds to a halt, mass chaos in the aisles of Tesco... ok slight exaggeration, but it has given me a few hours to get a post done on here.
While pricing roof cleaning jobs I have been asked a fair bit about Roof Coatings or Roof Painting as it is also known.
Breaking the Mould
Mould is easier to clean than
the soot of old, but with the return of clean air, nature has reclaimed ground
in a way not always foreseen.
Problems sometimes arise when
a building does not receive its full share of sun. In other places there are not
enough sunny days in a year to stop deleterious growth.
The issue does not affect all
materials in the same way. Most roofing materials will someday need cleaning,
but not all, and not at the same intervals.
Its been a while since my last post here, mainly down to the fact we have been very busy over the last few months. A complaint I hope to use more often!!
Anyway, I'd like to thanks those who have took time to read my posts over the last year, and those who have left comments, both positive and negative. Like everyone I learn from the opinions of others.
I recently came across an article written by an american guy called Jeffrey S. Levine, all about natural slate roofing and just wanted to share a short extract with you that highlights some important tips when it comes to repairing and maintaining this type of roofing.
Roof maintenance is very important to promote a long lasting roof. An effective roof is critical to the overall protection, insulation, security, and fiscal investment of a home. Neglect to this vital part of a property can result in significant damage and costly repairs or needed replacement. The type of roofing material utilized has influence over the best maintenance strategies to promote optimum roof condition. Regular inspection, cleaning, and other tactics will help keep the roof operational as long as possible.
I have been asked recently about some of the posts and comments I have been making on things like Facebook and Twitter regarding why you should never pressure wash your roof.
A power washing company recently sent me an e-mail asking for reasons why I think this. So here you go...
The three most commonly used roofing materials in Ireland are probably concrete tiles, fibre cement (man-made) slates and natural slates. I can give you a few examples for each as to why they shouldn't be pressure washed, and anyone experienced in fitting these products will tell you the same.
Algae are a diverse group of simple, plant like organisms. Like plants, most algae use the energy of sunlight to make their own food, a process called photosynthesis. However, algae lack the roots, leaves, and other structures typical of true plants. Algae are the most important photosynthesising organisms on Earth. They capture more of the sun’s energy and produce more oxygen (a by-product of photosynthesis) than all plants combined. Algae vary greatly in size and grow in many diverse habitats.
