Christy's Red Hot - Blue Glue
Combination glue and primer for flexible PVC
Christy's Red Hot Blue Glue is the original all-weather, wet or dry PVC cement
The Pond Advisor say...
This is by far the best PVC glue I have used for my solvent welds. The great thing about this is you can see were you don’t have enough glue on the black or grey pipe fittings.
Also you can see the join so you know 100% at a glance you have glue a fitting. Nothing worst than doing a dry run and then forgetting to glue them all.
