<p>A surface access cover (10) comprises a cover body (12). The cover body (12) has a primer layer (13) secured on a surface thereof. The primer layer (13) has secured thereto a resin layer (14) that defines an in-use engageable surface of the access cover (10). The resin layer (14) has embedded therein at least adjacent the said engageable surface a plurality of aggregate particles (15). At least some of the aggregate particles (15) give rise to undulations in the engageable surface. The primer layer (13) serves to bond the resin layer (14) to the cover body (12). <IMAGE></p> |
