VAPORiTe®+PLUS is a deep penetrating, high solids, water-miscible two-part epoxy system which is designed for the creation of a moisture/vapour barrier on cementitious screeds and concrete surface beds, where excess screed moisture poses a problem for the installation of moisture sensitive finishes such as vinyl, rubber, linoleum, textile and wood.
The product is designed to allow very low levels of vapour to permeate through the coating, at a rate which will not affect the performance of the flooring system i.e self-levelling screed, adhesive and above-mentioned coverings, thus allowing it to remain unaffected by rising, residual moisture within the substrate.
In the application of VAPORiTe®+PLUS, the substrate must be sound and free of any loose particles or dust. The surface must be thoroughly swept or vacuumed prior to the application.
Any contamination of the substrate, such as old adhesives, oil, grease, paint, bitumen, skim plaster or any other substance which can inhibit the adhesion must be removed.
VAPORiTe®+PLUS can be applied by steel trowel, mohair paint roller, or brush.
VAPORiTe®+PLUS must be applied in two coats directionally to ensure full coverage of the surface. This is to ensure no pinholing, or gaps are present in the finished coating. This must be done in a north-south/ east-west fashion, and care must be taken to ensure a defect free surface is achieved. Allow 4 hours between coats to ensure the product is adequately cured; this is highly dependent on atmospheric conditions thus this time may vary.
Care must be taken to ensure any ponding of the product is removed by means of a brush or roller to ensure a thin uniform coating is achieved. Failure to do so may result in prolonged curing times and affect the ability of the product to perform as prescribed.
Following the final coat, sufficient time must be allowed for the product to cure completely prior to proceeding with the application of iTeSLURRY®.
VAPORiTe®+PLUS comprises of two parts, which must be thoroughly mixed for 4 minutes with an electric paddle mixer. Care must be taken to ensure all the product from both part A and B are combined, as failure to do so could compromise the product’s performance.
VAPORiTe®+PLUS is suitable for use on porous cementitious surface beds, suspended slabs and wall surfaces where residual moisture levels exceed the permissible levels stipulated by the relevant floor covering manufacturer. The maximum is typically 3-3.5% moisture content (MC).
Should the screed moisture content exceed 6%, iTe Products technical department must be contacted for assistance on ensuring the application is performed correctly.
VAPORiTe®+PLUS yields a coverage of approximately 8m2/kg per coat. It must be applied in 2 coats, yielding a total of approximately 4m2/kg for the system. This will yield an approximate overall coverage of 18m2/4.5kg pack and is highly dependent on the porosity and conditions of the surface onto which it is applied.
Note: For the first coats, consumption is generally higher than that of the second.
Should LEVELiTe® self-levelling screed be utilised as part of the system, VAPORiTe®+PLUS must be utilised in conjunction with iTeSLURRY® as the key promoter.
Once mixed, VAPORiTe®+PLUS has a pot life of approximately 30 minutes. This is highly dependent on atmospheric conditions thus this time may vary.
Note: The 2 coats cannot be applied from the same VAPORiTe®+PLUS 4.5kg pack.
