Best Bond is a versatile PVA bonding agent and mortar additive supplied in a 4L bottle, suited to a wide range of building and renovation tasks. It is ideal for cement toppings, rendering and sealing, and works well for plaster and hard plaster work as well as dust proofing. As a bonding agent it helps join new concrete to old, improving adhesion between fresh and cured surfaces so patches and toppings hold firmly. Added to a mortar or render mix, it improves workability and bond strength, while as a general adhesive it also performs in woodwork and carpentry applications. Reliable and easy to use, Best Bond is a practical choice for builders, renderers and DIY renovators who need dependable bonding across masonry, concrete and timber. Note that it is not suitable for continuous exposure to wet conditions, so it should be reserved for internal and protected external applications rather than areas of permanent water contact.
