这怎么理解？ paint over in 60 minutes

liaotang

在用Selleys , Paint Over SIlicon，
paint over in 60 minutes
。 什么意思？
1》 必须在60分钟内油漆， 否则SILICON 干了后就油不上了。 （ 一般的silicon 是油不上漆的）。
2》 必须在60分钟后油漆， 否则SILICON 还没有干，油不上了

How to use this product
- Ensure you tape both sides of the gap before applying the product. This ensures a neat finish and makes it easier to clean up.
- When first applying product, extrude a small amount onto a piece of scrap material to ensure a smooth continuous flow of silicone sealant.
- Remove the tape before the silicone sealant skins.
- For a better finish use a spatula dipped in detergent and water to tool off the sealant.
-
Allow the surfaces to skin prior to painting, which is approximately 30 minutes
. Protect from rain until firmly skinned. Allow for longer skin and cure times in damp conditions.
- Some water based under coats & flat paints may crack on drying. To reduce this effect allows the product to cure for 24 hours in small gaps or 48 hours in larger gaps before painting with such paints.
- To improve the paint finish, wipe the sealant with detergent solution immediately before painting.
- Avoid smearing sealant on the surrounding surfaces as this may effects its paintability.
-
Ability to paint is reduced over time as the product contains silicone oils.
Paintability reduces after 48 hours. Paintability can be improved by over coating exisiting sealant with a fresh layer of sealant.
- Work in sections that can be completed before sealant skins. Tooling off and tape removal must be completed before skinning occurs or a rough surface may result so working in sections allows for a better finish.
- Keep a pack of SELLEYS Hand Kleen Wipes handy to wipe up any spills and for cleaning any material off the skin before it cures. They are an easy and effective way to keep clean on the job.
