Best to apply in warm weather . But I warmed the flash band as I didn’t have that benefit so it was extra sticky **Q: does this include 2 items - roll of flashing tape and tin of paint on primer** A: Yes is the answer,to your question,when you purchase flashband 150mm x 3.75mt.now the primer does not always come with the product,its main use is for use on on unstable surfaces,ie flaky surfaces.FLASHBAND was a evo-stik product,and I have used it for over 30 years,having sold it to trade and retail,whilst working in builders merchant.great product,many uses. **Q: does this include both the Flashing tape and a tin of liquid/paint on primer - so separate items?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product, when used right! *by A***A on 1 January 2026* Works really well, plus comes with the added primer which is just about enough for each role, adding a little bit of water to the primer helps it spread over well. I'd definitely recommend using a heat gun with this, to get the adhesive backing / tar melting for it to stick well to surfaces and activate the adhesive, otherwise it will fall off, especially on cold days. Great product when you know how to use it well! ### ⭐⭐⭐⭐ Sticks well once warmed up. *by A***R on 31 March 2026* Good product but easier to use in the summer. ### ⭐⭐⭐⭐⭐ Good DIY product - with PRIMER included *by B***E on 1 June 2025* Great product, sticks well and easy to cut. Difficult to manipulate into tight spaces and secure over uneven surface - but no fault of the product. Comes with small tins of PRIMER inside centre of roll - I missed that and so bought a tin of primer - which helped seal the surface prior to sticking down. Would buy again without hesitation. ## Frequently Bought Together - Bostik Flashband Self Adhesive Flashing Tape for Roofs, Provides an Instant Watertight Seal, Colour: Grey, 100mm x 3.75m Complete With Primer - ZIP System Liquid Flash | 29 oz.
