200' (Feet) Roll - Old Style Elite Greenhouses Glazing Seal - Non Setting Butyl Mastic

Used for putting glass in greenhouse . Excellent and easy to use. Arrived on time too.

Used to replace rubber grip type glass contact surface for aluminium and glass greenhouse.Does the job.Issues:Stretches as you pull, so could have been twice as wide imo. But also stretches when pressure applied, so you can mould it on with minimal pressure and practice. Also the glass compresses it when added. Overall good deal.It’s sticky stuff and hard to work. Sticks to itself. I threw some water over the strips while still on the paper it and worked with hands a bit damn and that made life easier.Overall, I’m theory a better seal than the rubber strip option. And you don’t need to get the exact right rubber strip size. Could do with being a tad wider to make it easier to work with.I’ll probably use the camper mastic for gaps not quite covered by greenhouse design.

Bit tricky but works as expected. Great job

Very tacky, just as it should be. A bit of a fiddle to fit until one gets the hang of it. Could be a bit thicker as it is inclined to stretch a little during fitting, but that's down to my inexperience rather than a product fault.

The product its self is Great, but the weight of the Roll is difficult to use on your own. So have to cut it into smaller pieces.

This is an easy to use, perfectly designed product that just works.Very impressed, replaced all the roof panels of an 8'x6' aluminium greenhouse in about four hours: remove, clean glass & old mastic, re-mastic, re-glaze and put in new clips.

Great alternative to rubber inserts. Grips the glass giving you time to attach clips.

Very good product
