Sealing hallmark brickwork

lastbuilders

I moved into my self build last year and am hoping to seal the brickwork before the end of th year. The whole external of the house is Hallmark Nickle blend brickwork.



I was hoping to get some pointers on doing this or what products to use for it?



I have seen sika and Thompsons brick sealer in the builders providers. The sika is much more expensive. Is there a difference between them?

If your walls a a modern cavity construction, outer leaf brick,gap,High density insulation, inner leaf block or timber frame with a brick skin why do you want to seal the brick ?

Hi bradnailer,

It is a new build of timber frame construction. My query was really if it is recommended practice to apply a sealer to this type of brick or not. If not then it saves a lot of brushing for me.

I'm not familiar with the particular brick, I wouldn't think sealing the brick was required, even if there is any water that makes it's way through it's not going to affect the inner leaf.
A Engineer once told me that the outer leaf of a traditional cavity build runs wet on the inside during heavy periods of rain, the whole idea is that it doesn't make it to the inner leaf, providing all ties ect are installed correctly
