Vysa-Bond RAPID Fast setting adhesive for bonding Vysa-Pron to all sub-floors
Vysa-Pron thermal insulation sheets are the most convenient, cost effective thermal floor insulation for use with all electric underfloor heating systems. They provide an essential function for the economic operation of your installation throughout its lifetime
Vysa-Pron thermal insulation sheets must be securely bonded to the sub-floor to ensure that the final floor finish has integrity once applied.
We offer two high performance adhesives for Vysa-Pron thermal insulation sheets. Vysa-Bond RAPID adhesive is suitable for non-porous surfaces. Vysa-Bond PLUS adhesive is suitable for use on porous surfaces.
Vysa-Bond RAPID adhesive
is a single component, moisture curing polyurethane adhesive developed for use as a rapid setting adhesive for bonding Vysa-Pron thermal insulation to non-porous surfaces.
Vysa-Bond RAPID has two main purposes when bonding Vysa-Pron thermal insulation to sub-floors
A) Bonding non-porous surfaces such as:
1) Smooth or polished concrete sub-floor.
2) Floor covered with self levelling compound.
3) Floor with a water resistant epoxy membrane.
4) On top of existing ceramic tiles.
B) Rapid cure so that installation can proceed without any delay.
Vysa-Bond RAPID will cure in about 30 minutes at 20°C.
Vysa-Bond RAPID must be used at temperatures of 10°C ~ 25°C
Vysa-Bond RAPID is the professionals’ preferred adhesive because it enables them to be certain that a strong bond has been established between the Vysa-Pron insulation and the sub-floor whatever the type of sub-floor.
NB at temperatures below 10°C even Vysa-Bond RAPID takes longer to cure and should be left overnight.
PREPARATION It is important that the floor surface is grease free and swept clean of any contaminants liable to impair adhesion such as loose particles and any dust.
APPLICATION Vysa-Bond RAPID should be applied neat to the sub-floor surface only using the roller provided. It should then be ‘activated’ by spraying a fine mist of water onto the adhesive layer. Once ‘activated’ the installer has only 10 minutes to lay the Vysa-Pron thermal insulation sheets. Planks or sheets of plywood should be applied to hold the insulation sheets in contact with the adhesive as they have a tendency to curl or lift.
COVERAGE 1 kg can cover from 3 to 5m2 – depending on the floor surface.
STORAGE Store Vysa-Bond RAPID in cool dry conditions between +5°C and +25°C . Lower temperatures can cause permanent damage to the solution. Protect from frost.
Vysa-Bond RAPID has a shelf life of only 3 months. Please refer to the date stamp on the bottle to ensure that the Vysa-Bond RAPID has not exceeded it’s shelf life.
NB The bottles of Vysa-Bond RAPID are sealed with a Nitrogen atmosphere during packing so exclude water vapour which initiates the curing process. A partially used bottle of Vysa-Bond RAPID will not keep for later use because the water vapour present in the air will cause the contents to cure.
