| + | It is very important that these are well maintained as leaks from them are a frequent source of water ingress to buildings and cause expensive and destructive outbreaks of dry rot. These items are made from cast iron, which can rust. | ||

| - | ===== How to fix ===== | + | |
| + | Examine the pipework, gutters and rain-hops carefully for any cracks or loose joints – watch for tell-tale marks on walls after rain. These must be repaired before any repainting is done. | ||
| + | ===== How to fix ===== | ||
| + | |||
| + | Any areas of rust should be wire brushed back to a clean bright metal surface and then primed with two coats of a suitable metal primer. For more information see [[Railings]]. | ||
| + | |||
| + | The insides of gutters were traditionally painted with two coats of bitumen or tar as this is extremely water proof and is still the best material for this use. | ||
| + | |||
| + | === Re-painting Pipework === | ||
| + | |||
| + | Some older down pipes may have been previously painted with a black glossy bitumen finish. This can bleed through a paler coloured oil paint applied on top of it, giving dirty and unsightly brown streaks. To check if this is likely to happen, rub the black surface vigorously with a rag soaked in white spirits to see if the black paint will soften. If you do get streaks, then the black must be sealed with a bitumen sealer before applying an oil gloss paint, or a water based masonry paint can be used; this should not discolour. | ||
| + | |||
| + | Down pipes and the underside of gutters are frequently painted a stone or grey colour in a gloss finish to blend into the stone. One colour that is particularly successful is called ‘Jim’s mix’, which is a mixture of equal parts of BS 08 B25 and BS 12 B21. //[NOTE: check if this is appropriate for Wirral Council Conservation]// | ||
| + | |||
| + | As an alternative to black gloss finish, there are other excellent hard-wearing paints which are suitable, such as dark grey micaceous iron oxide paint which gives a discrete matt finish. | ||
| + | |||
| + | It is often possible to find the original colours used on doors, windows, ironwork or other painted areas by examination of the hidden paint layers. | ||
| + | |||
| + | Where the wall is being painted with a masonry paint, the down pipes may also be painted in the same material to help camouflage them. | ||
| + | |||
| + | However, changing colour from Black may require [[seeking_list_planning_permission|Seeking Listed Planning Permission]]. | ||
| ===== Avoiding creating problems ===== | ===== Avoiding creating problems ===== | ||
| + | |||
| + | Do not use plastic or PVC piping for down-pipes, gutters or rain-pots. | ||
