Glazed terracotta tiles are extremely slippery and the utmost care must be taken when walking on them, the use of anti slip shoes is recommended. Terracotta tiles are extremely delicate and are prone to shattering, extreme care is required when walking on them.
Prior to restoration disconnect downpipes which are connected to rainwater tanks or direct water into garden bed or lawn. Following the coating application leave downpipes disconnected for at least two significant rains or wash the roof after three weeks of curing.
Cut a small cross hatch through existing paint with sharp blade. Press cellulose tape firmly across cut and rip tape off. If paint comes off, it is unsound and should be removed. Repeat test at random across painted surface to test soundness of area.
Ensure all screw and nail fixings are fixed correctly. Replace all rusted screws and any faulty sheet or valley irons as required.
High-pressure wash with a minimum of 4000+ PSI and a minimum flow of 15-23 litres per minute with a turbo head/nozzle to remove dirt, excess grime, lichen, moss and other contaminants.
¹PREVIOUSLY PAINTED SURFACES: High-pressure wash with a minimum of 4000+ PSI at 15-23 litres per minute with a turbo head/nozzle to achieve a satisfactory clean surface before application commences. Multiple passes may be required to effectively remove previous coatings.
Note: Allow the roof surface to completely dry between 1st and 2nd pressure wash, prior to the application of new coatings. Any remaining paint film should be checked using the cross hatch adhesion test to determine if existing paint is sound prior to coating – Refer to data sheet for full details.
Use a power tool or wire brush to clear all loose or flaking rust, where applicable. Then clean down with a broom or blower to remove all rust contamination or loosely bound material.
