LaChab Posted December 16 Share Posted December 16 Hi, I'm planning to use EWIPro 225, 333 and 076 on our eps blocks. I just wondered whether it's necessary to rasp and or wash the blocks first, and whether we should use 310 primer first under the 225. The blocks are about 6 months old, so not dusty yet. Thanks for reading. Link to comment Share on other sites More sharing options...
ChrisJ Posted December 16 Share Posted December 16 (edited) I don't know the product you are using but any that I have used all requiring rasping The block maybe clean but its also got too smooth a surface so the base coat will not adhere and be loose and potentially fall off And even tho only 6 months old I can assure you there is some UV damage and a light film on it, rub your hand across it and you will see it on your hand but maybe not visible to see Edited December 16 by ChrisJ Link to comment Share on other sites More sharing options...
Conor Posted December 16 Share Posted December 16 Leave that up to your renderer. All of our walls were rasped. Link to comment Share on other sites More sharing options...
