Daughter moving into a house where the floor has just been dug up, insulation stuff plut down and floor screeded, finished about 5 days ago. every time its swept more dust comes off. what can it be sealed with please?
thanks,
annie.
there is at least one bonding liquid you can paint on, think Polybond may be a brand (made by polyfilla), and you paint it on, leave to dry and that's it sealed. Get it in paint or DIY shops. Works quite well!
Ronseal make a liquid concrete seal - 5 litre tin covers 30 sq metres and costs around £38 from B&Q. Apply with a roller, it soaks into the surface and is touch-dry in about an hour. We used it (or something similar) on our garage floor about 15 years ago and it's still completely dust-free.
