I have just had a conservatory installed. We have not decided which type of
floor to have laid on the concrete yet and may take a while to decide. Can
anyone advise me of how to seal the concrete to prevent dust being blown up
when you sweep up.
You could paint it either with masonry stabilising solution, or with PVA
adhesive, one part PVA diluted with four parts water. Either solution will
seal the concrete. You may need to apply two coats. Stabilising solution
works out more expensive but is no better in my experience. You will find
both products in many hardware stores, DIY sheds and builders merchants.
Roger, PVA is an adhesive in its original state but is also used to seal
porous surfaces such as plasterboard and concrete when diluted with water.
If bought in 2.5 or 5 litre containers for building use it explains on the
container which dilutions to use for different jobs. Regarding PVA and
latex, I can't answer that, I would check that out with a flooring
contractor. Good luck.
