Everbuild 501 PVA Bonding Agent 5L

This 501 PVA bonding agent from Everbuild is a construction-grade glue that helps to insulate and strengthen porous building materials to help them last longer. Use PVA Bond to seal your wall before applying paint, or to bond flaking concrete and mortar, increasing the life of your structure. 
The substance spreads well before setting so you can apply it easily. The glue also works for crafting and more detailed DIY work, and you can dilute it to achieve the right consistency for your application. It is constructed in compliance with BS 5270, the British Standards Authority's criteria for safe-to-use sealants.
