Preparation work
When painting your cement or concrete tiled roof remember that preparation is most important! Before you do any work on your roof you have to remove all down pipes. Then, you will need to apply with a soft broom Mouldshield C diluted 5:1 with water then pressure washer your roof to clean it, preferably pressure washer that has a pressure of at least 3000 psi. While you are up there you need to check that the ridge capping tiles are in good condition, it is most likely that they will need at least to be re pointed with Roofbond Flexible Pointing. If some of the ridge caps are loose then you will need to re lay them with Shieldcoats Ridgerite before you apply the Roofbond Flexible Pointing. Also check that there are any broken ridge caps or tiles, and replace them with new or second hand ones. Note that they don’t have to be the same colour as your existing cement or concrete tiles as you are about to paint them all. Just ensure that they are the same style cement tile as your existing cement tiles as your roof.
Preparation coatings
It is important to evaluate the condition of your cement tiled roof at this point before you proceed with purchasing your preparation and finish products to ensure a long lasting durable job on your cement or concrete tiled roof. Check your valleys to see if they are rusty, if they are you will need to wire brush them down and apply a coat of Rustseal or Rustshield W and allow at least 24 hours to dry before applying your finished coats. Next, you apply a coat of Shieldseal W to seal your cement or concrete tiled roof, allowing at least 4 hours drying time, depending on the weather.
Finish coatings
Then you apply 2 coats of your desired colour of Roofbond Roofing Paint to your well prepared cement or concrete tiled roof.
