RICHARD+PHILIP Posted March 4, 2022 Share Posted March 4, 2022 Echoing Damper man The 2 on block garages I have done without electricity I have sweeped the floor first, dampened and mopped any remaining grit Then then mixed a 90/10 mix of white spirit and floor paint to get the paint into the floor, once dry (which takes a few days) roll on the remaining neat paint from the can. Pretty sure I used Dulux floor shield although looking at the spec sheet that does say don't use in car showrooms. 2nd garage I used cheaper wilkinsons floor paint which has stuck fine and was half the price but I used double the quantity.

Mole Posted March 4, 2022 Share Posted March 4, 2022 Without sounding like a modern day health and safety executive.. please note that silica dust is the new asbestos..and I am sure there I'll be loads of claims in the building industry in the future..well at least from the non self employed! Our local inspector says he does not sweep his garage floor with out a full mask on..and at work we have to vacuum rather than sweep because of the dust hazard.. So wear a decent mask if you are working in the dust.. Quote Link to comment Share on other sites More sharing options...

I have also dampened the floor first to keep the worst of it down 'cos toxic or not, it's still pretty unpleasant. 1 Quote Link to comment Share on other sites More sharing options...
Marcus Barlow - Show and Events Co-ordinator Posted March 5, 2022 Share Posted March 5, 2022 Ive used this on my garage floor which was bare dusty concrete which also had damp seeping up through as its an old garage which I think has no dpm under the concrete, its has stood up pretty good after two coats no dampness any more and doesn't get dusty https://www.screwfix.com/p/no-nonsense-trade-floor-paint-grey-2-5ltr/74591 Quote Link to comment Share on other sites More sharing options...
SXRORY Posted March 6, 2022 Share Posted March 6, 2022 i have done the hoover and pva mix like others. its ok, does work needs doing again now. I also after this, used one of the strips and it stuck to the floor fine with the sikaflx it came with. that has held up very well Quote Link to comment Share on other sites More sharing options...
Blatman Posted September 16, 2022 Author Share Posted September 16, 2022 OK, so as per my OP, I want to stick down that weather strip. After much Googling and Youtube-ing, and heeding the excellent advice here I settled on some Evostik PVA. Of course, I wanted to test it. So I also purchased some black solvent free polymer adhesive and stuck down one of my old trainers... I mixed the PVA in a strong 4/1 mix of water/PVA, brushed a section of floor to clear dust and debris, spread the PVA solution and allowed it to dry. It darkened the floor quite significantly which I don't care about, but be warned. Then I took my trainer and coated the ball of it liberally with adhesive and placed it on the gnarliest roughest bit of floor I could find. I weighed it down and left it to dry for two days. All I can say is that I now need to invent a use for the trainer that seems to be permanently attached to my garage floor... The weather strip goes in tomorrow 😄 😄 😄 4 Quote Link to comment Share on other sites More sharing options...
Terryathome Posted September 17, 2022 Share Posted September 17, 2022 You should have used SBR not pva as pva is water soluble. 1 Quote Link to comment Share on other sites More sharing options...
Jim RS Posted September 17, 2022 Share Posted September 17, 2022 Always used SBR as a bonding agent between existing and new. Maybe good to use a watered down primer then full strength for the bond coat, all according to the strength of your concrete. Just remember your concrete is fairly rigid and the stuff you adhere to it may be flexible so the difference in this must be taken into account.

Blatman Posted September 17, 2022 Author Share Posted September 17, 2022 Well it's done now. If the adhesive does it's job the underlying PVA will never get wet. But we'll see. We had to use tools to remove the trainer and the adhesive that remained is so far resisting our attacks... Quote Link to comment Share on other sites More sharing options...
Blatman Posted November 16, 2022 Author Share Posted November 16, 2022 Terry and Jim, you were right. The PVA dissolves pretty effectively and unsticks the weather strip I shall set about removing the weather strip, washing off the PVA and using SBR before bonding a(nother) weather strip to the floor. I have to say, prior to the biblical rain the weather strip and the adhesive stood up very well, keeping everything out of the garage, but the sheer volume of rain we have had recently simply overwhelmed the preparation and water forced it's way in. So, plan B starts with SBR!!! 1 Quote Link to comment Share on other sites More sharing options...
Blatman Posted January 26, 2023 Author Share Posted January 26, 2023 Ok, so PVA washed off, SBR applied along with copious amounts of black polymer bonding/sealing adhesive. They have survived the winter and snow etc with no issues at all, so no water coming in the door. However, now we KNOW that there is no water coming in the door we have discovered water coming through the breezeblocks from next doors garage (which must be epically wet inside) as well as possibly up from the ground. I have tried to seal this already with Bostik Cementone but it cracked which was both annoying and also revealing as I hope can be seen here: So my next thought is to seal this area with Bostick Flexacryl. Any thoughts or better options? I don't want to lay a new concrete floor (yet) as the garage is rented, and the landlord is unlikely to spend any money on it (long story...) so repair to stop as much water as I can is what I am looking at.

Jim RS Posted January 26, 2023 Share Posted January 26, 2023 This infiltration of water is difficult to seal and prevent. Any waterproof coating will allow any water to still find a way through. The way I solved leaking structures was to render them using a product called "Xypex", this you can mix with a standard sand/cement mortar and screed over the blocks. It basically works by growing crystals into the damp areas and forming a waterproof structure, the wetter the problem the more the crystals grow and they stay active even sealing cracks that may develop later. In fact sometimes the repairs can produce a white powdery coating which is a sign that the material is working quite hard. Some of their products can seal up flowing water when applied correctly. As with any product that works the costs are quite high but I can vouch for the stuff and I used to give a warranty on the finished work. Xypex UK are based in Malvern, however they don't stock materials there, just contact them for advice. Quote Link to comment Share on other sites More sharing options...

Thanks Jim, I'll take a look But first, I wonder if Amazon will bulk deliver the feminine hygiene devices. It a good job they are thin these days. I can post them under the adjacent garage door... 1 Quote Link to comment Share on other sites More sharing options...
