Stone wall sealants

[WelshDadOfThree]

Since our flooding, we've decided to leave exposed a few walls that were previously behind stud walls. I've nearly completed the raking out and repointing with lime and thanks to all the good info from this forum, I'm going to repoint the outside and install a zebcolm trench.

Once the non stone walls and ceilings have been plastered we'll be looking at decorating and the question has been raised about sealing the walls to stop dust etc. After a good chat with uncle google, I came across these two and wondered if anyone has had any experience with them:

Kingfisher Dust Sealer
Kingfisher Extreme Climate

Both claim to be breathable and usable for stone walls. The dust sealer will be used on some red brick walls in our lounge but could be useful on the stone walls and will likely enhance the effect of the ironstone. The external one looks like it could be really useful for the outside that is exposed to driving rain and currently we're getting moist patches on the newly exposed internal wall although that side does need repointing.

Thoughts would be appreciated

Let’s talk about the sealing you’re considering for the internal walls:

What precisely is the concern you have about plastering your stone walls which you are looking to this product to address?

Edit: oh I think you’re saying that you’re not going to plaster the stone, you’re just leaving it bare and you’re worried about the walls being dusty to the touch?

That's correct, bare stone walls. The brick walls we have generate quite a bit of red dust which this should help. I'm conscious that the newly exposed stone wall could add to that

Ok I understand what you're after now, sry that was my misunderstanding. I've never used any stone sealer personally so I shouldn't comment on that part. I do question whether it's necessary as long as the stone is properly scrubbed / rinsed / hoovered and all the pointing is brushed back with a churn-brush. Maybe they are still dusty after all that, idk. I am just thinking about the outside surface of our stone walls and I don't think those are constantly producing dust. Maybe they do and it just blows away in the wind or is washed away by rain and therefore I never notice it, not sure.

Although it's normally recommended to seal masonry in bathrooms and kitchens, I didn't bother when I did our kitchen, which I put a lot of reclaimed bricks into, and my wife hasn't mentioned anything apart from woodworm frass coming from the oak beam.

I've bright red bricks that seem much softer than the ones in your pictures. I'll take a few next time I'm there

Presume you don’t want to limewash then? Limewash with a bit of casein added (purchasable pre-mixed from Ty Mawr or Mike Wye) would 100% do the job but might not be the look you are going for

These will be getting sealed as they shed dust more than the dogs shed their fur:



This is the recently pointed toilet. I was going for the "built by a farmer look" as it is a barn:


Its this that I'm considering sealing
