Render, like all things can get a bit grubby over time.  If you don’t clean your car or your windows, they become grubby and dirty and render is no different.  Brick, cladding, fencing, glass, paint everything that is left outside can get a bit grubby over time.  Luckily render is very easy to keep looking its best if some basic routine maintenance is carried out.  Like having your windows cleaned, render loves a wash down.  You can do this yourself, or there are a number of specialist companies that are very experienced in this.  For now let’s assume you are going to do this yourself.  You don’t need much, but a trip to Screwfix or B&Q (there are other suppliers out there…) and grab a small 7l hand pump vacuum sprayer.  They are not too expensive and can be used for lots of odd jobs round the house when you aren’t cleaning your render.  Now buy some Alkem for your local Rowebb depot.  Available in 5l and 25l drums, Alkem is an environmentally friendly algaecide that works very well on most grime, dirt and algae that we come across.  It can be diluted down 1:5 with fresh clean water, or used neat for areas that need a bit more oooomph.  Add/dilute this in your spray bottle and then you are ready to go.  Choose a dry day and a time when you are forecast to have a few dry days thereafter to give the Alkem a chance to work.  Don’t apply this on a windy day as you will only be causing yourself more problems than you need.  Use protective equipment and remember, this is an algaecide and should be treated with care. It is not lemonade……  Now you have chosen a good day for the application, spray it onto the render from top to bottom.  Be careful that you cover the entire area.  You don’t want a big grubby patch in the middle of a beautiful clean wall at the end.  Spray each elevation with your Alkem mix and the leave it.  Once everything has been sprayed you really are finished.  Just sit back and wait for the Alkem to kill off any algae and the rain will wash it off.  If you feel it isn’t quite clean enough, give it another treatment. Some times it can take 2 or 3 treatments, depending on the location or how much maintenance has been carried out over the years.  Each job is slightly different.

We can also supply some more aggressive cleaners if required, but please call us for details on this.  Alkem is a great product and should improve most areas.
