Virobond 505 should never be applied if within 24 hours of application, the ambient temperature is going to drop below freezing, (0 degrees Celsius).
Do not apply Virobond 505 to any non-alkali bearing material, or glass, glazed surfaces, or aluminium, as etching will occur. Use protective coverings to ensure no over-spray contact or wind carried contact. In case of accidental contact, rinse thoroughly and immediately with water.
- Virobond 505 is not meant to fill or seal cracks.
- Virobond 505 does not stain proof.
While a surface properly treated with Virobond 505 will not allow the penetration of any liquid material below the top 1 to 2 mm, materials can penetrate and staining could occur in that top 1 to 2 mm. Therefore, if no other coating, paint, etc., is to be laid down on top of the Virobond 505 treated surface, and a higher stain resistance is required, Virobond 515 (Top Layer Sealer) has been specially formulated for this purpose, and to fill the top 1 to 2 mm, contact your Virobond 505 dealer or distributor on information about Virobond 515 (Top Layer Sealer).
For surfaces not specified in our literature or if uncertain as to previous chemical treatments, we recommend that Virobond 505 be applied to a small test area prior to application.
If Virobond 505 becomes frozen, thaw out completely and shake well to fully remix the material prior to using. Freezing will not harm the product.
