Plaster Finish Instruction
All our invisible speakers are already primed with Ardex P4. For further processing, we recommend a filler based on a gypsum-plastic base. We have tested the following plaster:
– Ardex 828
– Ardex R1
– Ardex 820 Superfinish
– Knauf Uniflott (available in most DIY stores)
(For the US market a pre mixed joint compound can be used with standard drying time)
Do not apply more than 2 mm of filler. Less is more, otherwise the maximum volume will be impaired.
In addition, a joint tape should be used, this is especially important with our full-range speakers and subwoofers to strictly prevent cracking in the wall and ceiling.
We can recommend the following jointtapes:
– Knauf Easy-Tape
