How to Build our Brick Oven Kit | 11. Rendering the Dome

The Ceramic Fiber Blanket that's insulating the oven dome is dense but soft, and easily soaks up any water that gets to it. We take you through the process of applying a 50mm (2") thick render shell over the blanket, which not only protects it, but gives you additional insulation. The Perlite used in our render mix is treated in a solution to coat each particle so that they don't soak up water (which normal Perlite does very well, that's why it's used in hydroponics). You'll mix the Perlite with GP cement, Lime and Wash Sand to create a strong, lightweight insulating render. We recommend putting the render on in two or three layers, which makes it much easier to do.

Our Wood Fired Oven Kits are available in Australia, the USA, Canada and New Zealand! Check out the links below:

Hey Ben, I love your videos your knowledge is impressive. Can you use high heat mortar with perlite for the rendering of the dome? Thank you for your help and your videos!

[olelarsen]

A well directed video...thanks for taking the care!! Will the render also act as a water proofing from the rain and weather too? Hope you wont read this now and are enjoying your xmas break :-)

Hi Ben excellent video, I texted last year asking if you are supplying to UK and to advise using heat resistant rope belween the dome edges not sure if you are now using that .Another question now is that have you ever heard of using foil over the insulating blanket before you apply the render, I heard it prevents the insulating blanket absorbing the moisture from the render, is this true

Hi. Can the perlite render be extended over the top and sides of the brick arch and over the flue gallery to insulate them? In another video you mention that the flue gallery gets very hot which concerns me a bit. I'm also thinking this would then allow me to extend the dome finish (render, tiles, pebbles etc) over those parts as well as I'm wanting a more "rustic" looking finish and not sure about the black paint would fit the style of my place. Thanks.

Any chance that an ecommerce site exists that extra Floats could be purchased for delivery to the US? Or even to be shipped from Down cant cost too much to ship a few pieces of foam?

Is the perlite mixed with regular cement or refractory cement? Thank you!

[rajanshrestha]

Great videos Ben. Just one question, what do you add to the perlite render to water proof it?

[philkalowski]

Where can I buy lite fill perlite in the states ? can’t find anything other than the kind used in gardening thx

[JoshHenery]

I've seen other people on youtube use a perlite render and it looks rough, how do you get a smooth render? Is it a finer grade perlite?

[sanman]

can we do away with perlite and just use the regular cement ?

[Jim-K-Baker]

If I'm putting it on in layers, how much should I mix at a time?
