A Poll for Primer Application

roller or brush, depending on the size of the area.

Roller on floors, sponge on walls

Roller

Sponge or brush for walls, and for priming plywood floors I use a grout float. What type of roller do you all use? Never tried a roller on floors but sounds like a quick way of doing it.

For priming over old tile adhesive before SLC, I use a stiff brush. Pulls the primer back out of the grooves.

I might try a spray bottle, sounds efficient

I'm losing big style with the sprayer!!!!
It does work, not on all stuff, it's controlable and then you can back back roll for floors or wipe with a sponge for walls, it doesn't run down your arms.

What sprayer would you recommend? Just general purpose spray bottle?

 

[d noulton]

brush for me

 

[Peter]

A pressurised spray pump would be a good job perhaps.

i'm not a fan of spraying primers. i think its better to use a brush or a roller so it actually gets worked into the substrate.
if a surface substrate is low suction then a sprayed primer can sit on the surface whereas a brush or roller agitates it in more.
