Do you want to know how to apply a roof membrane to a tile roof surface?
The coatings experts at Globalcote have put together a step-by-step guide below to make the process as smooth and hassle-free as possible.
Most people will know that there is plenty to be done before the first lick of paint can be applied, but there are quite a few tasks which need to be done before coating a tiled roof.
How to Paint A Tile Roof
Here’s your Step-By-Step Guide by applying Globalcote product to your tiled roof.
- Step 1: Inspect Surface
Carry out a thorough examination of the entire roof. Check if there is any moss or lichen, or if there are any loose or damaged tiles.
- Step 2: Replace defective tiles and valley irons
If you have any broken tiles or defective valley irons they need to be replaced.
- Step 3: Clean your roof
A high-pressure cleaner (at a minimum 3000psi) needs to be used to wash your surface down.
If you want a better clean you can use Globalcote Roof Wash, which can be applied at a spread rate of 8m2 per litre with a garden pump up sprayer or airless spray gun. Heavily soiled, painted surfaces may require brushing with a soft-bristled broom to remove ground-in dirt and/or contaminates. Wash the area throughly with water, ensuring no residue remains.
Warning: To avoid damage, due care should be taken on previously painted surfaces when using a pressure cleaner.
If your roof has been painted previously, any coating that is loose, flaking or blistered needs to be removed.
- Step 4: Rebed if necessary
If you need to rebed ridge capping, this can be done after cleaning. We recommend that bedding cement be applied by a trowel and mixed at a ratio of 4:1 sand to cement.
- Step 5: Repoint
The surface must be dry, dirt and dust-free before you apply Globalpoint Flexible Pointing to repoint all ridge capping.
Apply the flexible pointing with a trowel and ensure the thickness is uniform and between 3-5mm.
If you think it’s going to rain, we recommend spraying Globalpoint QuickSet where Globalpoint Flexible Pointing has been applied.
- Step 6: Sterilise your surface
Use Prepcote Surface Treatment before coating.
It can be sprayed to noses of tiles and any fungi/mould affected areas
We recommend using an atomising gun to apply the treatment.
Ensure the treatment is left on for at least 4 hours before moving onto the next step.
- Step 7: Seal your surface
Seal the surface with Primecote Sealer Primer at a spread rate of 8m2 per litre.
Depending on the porosity of your roof, you may need multiple coats to seal the surface completely.
Alternatively, you may need to use Primecote High Build at a spread rate of 6-7m2 to seal your surface.
*Expert tip: You should be able to tell when your surface is primed adequately, as the surface should be visible shiny.
- Step 8: Apply first coat of roof membrane
The first coat of your Globalcote Roof Membrane (such as Elastacote or Infracote) can be applied.
The spread rate should be 5m2 per litre.
- Step 9: Apply second coat of roof membrane
Add the second coating of your Globalcote Roof Membrane at 5m2 per litre.
