pva dot n dab brickwork

[jrob]

Do you pva before dot n dan on bare brick?


Best thing to stick plasterboard to a steel lintel, the underneth?


Brick opening is a bit rough, could i fill gaps with morter, then dot n dab, or use something else, some gaps about 2 inch diff in the brickwork, that was cut out


exterel corner do you leave a slight overhang when a corner meets, to make up for ther adhesive?

Do you mean bricks or blocks? Either way it won’t do any harm, will give you a bit more time but the adhesive won’t grab quiet so quickly.

Fort steel lintels, I always use a trade grab adhesive.

I would use render to fill the deeper holes; you could then use Bonding plaster (or render) to fill out level to D&D some PB or use either as a base coat to fill out & level, ready for the skim, depends on your skill level.

exterel corner do you leave a slight overhang when a corner meets, to make up for ther adhesive?

Within reason the gap wont really matter; make the corners flush & fix thin corner bead over ready to accept the skim coat.

I did say is or bricks or blocks but you shouldn’t really have had a problem with either; perhaps you did mixed it too wet!

If your filling holes use 4:1; as a base coat 5:1 or even 6:1 on new blocks; + a little Febmix in each case.

just damp the bricks down would be fine, dab some strips of board just to pack out. if you mean the head beneath a window just dab it with adhesive and use the boards for the reveals to hold it up. Try and measure it without the overhang other wise when you cut back it might run out. fill all the external corner with adhesive and it makes it easier to nail skim beads on.
