Why can't I tile over bitumen based waterproofing systems? deterioration of the integrity of the bitumen and tile adhesive, and a failure of the installation. If tiling is to take place over a bitumen-based waterproofing system we recommend that a screed, of at least 70mm thickness, be applied over the bitumen.
In this way, what will stick to bitumen?
Where its wanted for something to stick to bitumen, sand is sprinkled on while its wet. Cement, paints etc can then stick to the sand.
Subsequently, one may also ask, will SBR stick to bitumen?
When tacky mix self leveling floor screed , putting sbr in the screed . This will make the screed strong and will adhere over the Bitumen . The only problem being sbr additive is expensive .
A minimum of two coats of Bitumen Paint should be applied, the first been allowed to dry (normally 2-4 hours depending on weather conditions) before the second is applied. Surfaces should be dry and free of millscale, rust and dirt.
