Flashband : Do I need primer ?

[wbmkk]

A neighbour has just pointed out to me that there is a section of felt loose at the side of our dormer window roof. It looks as if the felt has broken along the corner (roof to the fascia board) with one section just hanging (1m in length)

We have a bungalow and with the layout, it's an easy fix, with no real risk of falling .. so it's a suitable DIY job

I'll buy some flash band, maybe 225mm wide, but I see some rolls come with primer and some don't.

Do I need to use primer for the flashband to stick to felt (roof) and timber (side) ?

Is there any need to overpaint it with any waterproofing after being done ?

thanks !

ps doing it in this heatwave will help I'm sure too .. so I better be quick

Use the primer if there is any degree of porosity - essential on timber.
Once the Flashband has been applied and rolled down it doesn't need any other protection but a coat of Acrypol or Evercryl (both fibre reinforced paints) does no harm and will give you more time.
