Got my speed skim

[spunky]

As a Darby jj or scraping it before you float it

Yes it tears it and puts loads of tiger stripes in it

you must have been using it wrong then, I use mine on both coats and get neither of the problems you had

 

[Ianspreader]

I don't always use it on second coat but never had problems with tiger strips with it but them plastic trowels they are a waste of time lol
