High Build Vinyl
A vinyl based, anti-corrosion primer/finish for metal. It is ideally suited to single coat, high build application and can be applied directly onto galvanized metal.
- For galvanized ironwork - no previous treatment or acid wash is required. However, surfaces must be dry, clean and free from dust, grease or oil. Hi-Build vinyl adheres directly onto galvanized or aluminium surfaces. After galvanizing, the ironwork is usually dipped into a tank of water to cool and in damp weather, this can take some time to dry thoroughly.
- For non-galvanized surfaces - the surfaces must be clean and free from rust, dust and grease. Although blast cleaning is best, Hi-Build vinyl outperforms most coatings on manually prepared surfaces. Two coats are usually sufficient.
- For pre-painted surfaces - as for non-galvanized surfaces, with the addition that any loose material is removed. Hi-Build vinyl is compatible with most finishes, however we recommend painting a small section to test compatibility first.
By spray, brush or roller. Please note that High Build vinyl is much thicker and conventional paints and should not be "brushed out" when applied. Use a well loaded brush and apply evenly. Two coats are recommended.
We recommend a minimum of 80 µ dft in normal conditions and 120 µ dft in salt water conditions. We suggest using a different colour for the first coat. This makes it easier to ensure that two coats are applied evenly (recommend stone grey when spraying). We recommend using a maximum of 15% Thinners.
NB : After galvanizing, some galvanizers use a chromate wash to ensure that the galvanizing stays shiny. This is fine when work is going to be left in a galvanized finish but can prevent adhesion of any finish. We do not recommend the use of chromate wash if applying a painted finish.
Coverage: Approx 5m² per litre @ 50 µ dft in good conditions. This can vary with the method of application
Composition: Based on a modified vinyl resin, pigmented with suitably selected pigments and zinc phosphate anticorrosive pigment.
