Does any prime there 6 mm ply before they put in bathrooms an kitchens , then just feather edge join

Does any prime there 6mm ply before they fit it in kichens an bathrooms ? Then feather edge all joins

 

I tend to feather the lot these days.
I prime after not before myself.

 

Might help the adhesive going off so quick ? Even help with the ply absorbing less moisture in bathrooms just thought be good idea to do ... Messy but maybe worth ?

 

Priming prevent your adhesive "retarding"
Sucking the mositure out of the glue too quick (esp with f44)

I prime all my ply floors
Defo improves adhesion to the plywood

Also you rarely will get perfectly clean plywood, always have contaminates on them

 

Gonna start doing it now

 

Always fball

 

Mapei primer t
Or Ardex p51 for me

 

Mapai water based screed is good ,so is fball 300 but what ever primer you use has to be the same screed you use in case all else fails . My opinion but love here what everyone else does

 

131

 

Neat

 

Should be neat according to the spec sheets from Ardex
But I do 2/1 or 1/1 on ply
It drys a lot quicker and don't really make much difference on performance

4/1 over the feather

 

You put water on you ply when you feather edge the lot , depending how wet or thick you have the feather edge

 

Or just sand all the joins and fuck feather off

 

Do you not like?

When I knife the radiator pipe
I normally flood the ply

Chinese ply is the best of gear
