Need best way to affix hardiboard to brick

[Cliff Newton]

I'm hanging new hardiboard on my house and have run across a problem area. I need to hang some trim on a bricked area. Is there some sort of adhesive available at my local borg that will do the job and hold up as long as the trim?

I am assuming that by hardiboard trim you are referring to the fiber cement types of trim rather than the polyurethane molded trims. Franklin or Titebond heavy duty construction adhesives are excellent for this purpose, with some caveats. Both remain somewhat flexible, therefore, heavy veritcal tirm or long horrizontal trim could sag after awhile. Your trim may conform to surface irregularities of the brick and look wavy over long runs. Also, the brick surface must be strong and clean - no glue can stick to poor surfaces.

Having said that, I would recommend you to anchor a nailer over the brick using a combination of masonry nails and glue. Shim low areas, shave high areas. That gives you better control over the finish trim and should provide a better looking finish. A photo would better define your problem area, I would be happy to take a look to offer other suggestions if you can post one.

I would also suggest that you call the glue manufacturer help line and ask for technical assistance. (Titebond Help line 800-347-4583) I do this often and have with great success.

Its not a bad idea to glue and nail a backer
to the brick as has already been noted
I have used this product extensively, never
had a call back.

I have used several of the PL products, including the PL400 & PL500 - always found the products to be very good. Have never used the PL Poly, but I would tend to believe it would be a superior product just as Per mentions - so I'll cast a vote for the PL Poly.

I have used PL premium to fasten backsplashes, and it is very good. Need
just a little. Clamped overnight it really stays in place. Never tried to glue
a board over brick. Jim

if you dont mind drilling holes in the brick you can use tapcons.
