Precautions to be taken in the process of sanding –
1. The hardness of epoxy resin – The epoxy resin gets hard after curing, which is the primary reason why sometimes it becomes hard to sand the surface as the abrasive paper becomes dull easily.
Try replacing sandpaper frequently when sanding epoxy resin.
2. The change of sandpaper – Sandpaper gets clogged and has to be replaced or cleaned from time to time, or else it will leave sanding marks on the surface of the epoxy resin.
For better results, check what sandpaper you use to sand epoxy resin to avoid complications.
3. The creation of dust – In the process of dry sanding, the emission of dust is widespread and tough to deal with. Use protective masks and gloves with a ventilated area while casting epoxy resin.
4. Excessive heat – The evolution of heat is often faced in dry sanding, which may lead to cracks in epoxy resin. As far as possible, opt for wet sanding to eliminate this issue.
1. Can we use warm water when performing wet sanding for epoxy resin?
Yes, in wet sanding, the water temperature can be anything from normal to mild warm, as it will not affect the epoxy resin in any way.
Avoid too cold or too hot water as it may make the surface of the newly epoxy resin get spoiled and prone to damage easily.
2. Is the process of dry sanding hazardous to health?
Well, when dry sanded, the dust emitted by epoxy resin can produce air-borne effects and damage the lungs and other respiratory organs.
The epoxy resin dust is carcinogenic, so proper double masks and hand gloves are essential.
3. What should be the grain size?
The grain size is available from 60-1000, but I recommend you start with 120 and increase it to 1000.
Too small a size can invite scratches to your epoxy resin surface, increasing your work and eliminating them, which is a complicated process. (Check whether you can sand epoxy resin with 80 grit or not).
