Exterior concrete stairs on block of flats must be anti slip and colour grey any products that suit that Many thanks Phil modern futures
We would suggest our 501 Anti Slip Floor Paint, existing painted surfaces should be cleaned, degreased and sanded to ensure an adequate "key" is produced. Remove all loose and flaking material and treat bare areas as new substrate and prepare accordingly. Bare concrete should be first primed with 10% thinned 301 Industrial Floor Paint.
