Fixing / Reinforcing Door Lining?

paperclap

Hi all,

We’re keeping our existing door linings, but fitting new (heavier) doors.

The door linings (going into brick or block) and the stops (going into the lining) are a touch loose in areas… so I’d like to reinforce them a little more, so they’ll happily take the weight of the new heavier doors. The door linings were undercut (for laminate to slip under), so no even less support now, as they’re not sitting on/in the floor screed.

What are the best nails to use for both jobs?

Thanks!

4 inch screws for the lining. Lost heads for the stop.

Thanks, but can’t / don’t really want to use screws for the lining… as the lining is already on the wall (no plugs behind it). Hence the need for nails

There are screws designed for fixing directly in to concrete & brick without the use of plugs - https://www.screwfix.com/c/screws-nails-fixings/masonry-screws/cat840054

You could also use hammer fixings - Hide them behind the door stops and counterbore the holes so that the head is recessed slightly.

You can drill through the lining into the wall. Then stick a plug on the end of the screw and knock it through. Then tighten the screw.

Dragged into the 21st century I’ve started using these, absolutely fantastic!

Do they hold well in Thermalite blocks?

I was very wary of them but they got delivered with some windows and a conservatory I fitted, so far I’ve had a solid bite in thermalite, soft red brick and standard brick, not sure how they would perform in an engineered brick though!

I'm old enough to remember the chippies using cut nails to fix the frames.

And I'm young enough to be cursing those same chippies. Just about every bit of wood here has multiple cut nails hammered into the bricks. Sometimes, three nails through one hole.

Still carry them!
When I was a youngster I was given an axe to cut wedges for brick joints then fitted skirting with cut nails!
Bomb proof!
