I have a contractor who has recommended Dow CWS as a chinking material. He says it will hold up well and can be stained over if we don’t want a contrast. What is your opinion on the durability of this product and it’s use as a chinking material? Will stain (Sikkens) adhere to this material satisfactorily? Thanks for your help. gary
