I watched the video on preparing the shower floor and the screeding, my question is "Do I seal the floor with a paint on water seal product. including taping the edges to the wall before I tile the floor"
Welcome to the Bunnings Workshop community @Laurens. It's a pleasure to have you join us, and many thanks for your question.
Once you have levelled and graded your shower base towards the drain outlet, you must apply a waterproofing membrane over the screed and up the walls. This includes taping the joints between the walls and the floor.
You should find these step-by-step guides useful:
The products to use would be Dunlop 1L Primer And Additive, Dunlop 10m Express Wet Area Waterproofing Tape and Dunlop 5kg Trade Range Express Wet Area Waterproofing. We also have a fantastic range of floor tiles that you might like to browse through.
Please let me know if you need further assistance or have questions.
