Wedi/Marmox on hardwall - dowels plus dot and dab or dowels plus full addy bed? - TilersForums.com

[Andysblacksoul]

Just about to line my en-suite out with Marmox boards onto the existing (new build) hardwall finish. Primed with Mapei G first and will use spankers/dowels but what's the consensus on dot n dab vs full bed of addy?

Will end up with 300 x 600 9mm porcs on top, but the spankers are there to support the weight? Walls are flat and true...

If the walls are very good trowel with a 10 mm notch and mechanically fix
