Hi,

Got screed down. Someone suggested 'painting' Unibond on to new screed to prevent dust rising. Is that a good idea ?
 
Unibond PVA alright - mixed it 4:1 (it specified 5:1) and spread it using a roller. What exactly does this do ? Should I notice anything ? It was difficult to get the PVA to dilute.
 
Its much easier to put on with a brush. :D

As it loses the water and binds with the concrete, the PVA / water emulsion forms a very thin flexible "skin" that prevents dust rising.
 
It's glue , just binds the dust together, stops it rising.. also forms a skin to stop new dust...
