Method for glueing wooden step to masonery using gap filling adhesive.

JohnB47

I have an oak step that I want to glue down onto a mortar bed between two rooms. I have bought some Evo Stick Gripfill and I'm wondering about how to spread it out.
I would usually go for the dab method - five or six blobs of adhesive, then place the step on and load up with several bricks above until the glue is set. The instructions say 'a continuous bead'. I could also spread a continous layer all along the mortar but that might hold the step too high.
Any advice?

how thick is the oak strip? what are you sticking it too, is that surface primed properly?
evo stick gripfill, I have never had much success with this stuff, it just seems to be about as sticky as an old lump of chewing gum or blu tack. I've always used sticks like sh**

Hi John.

Many adhesives will do this job, from cartridge-delivered 'sealant' types like the one you mentioned, to 'expanding' types such as Polyurethane adhesive (eg Gorilla Glue). The method is the same - you can't put on too much, unless it actually squishes out the sides... (the Poly type might do this).

As Fenwick says, tho', the adhesive will only be as good as the grip on the mortar. If this is 'dusty' or loose-surfaced in any way, then the set adhesive could easily peel off. It might therefore need sealing first with a watered-down coat of PVA or stabilising liquid, but that's your call.

My own personal fav adhesive for most jobs is Everbuild 'StixAll'. This sets like 'rubber' and is very tough and sticky.
