Cpes before caulking

I've now got some caulk - I ended up with Sika 290i DC from Whitworths - so over the next couple of days I will clean out the problem caprail and toerail joins and hopefully get some caulk a reasonable way into the gaps. With the gaps sealed I will wait a bit longer before starting on the strip and CPES phase. Well, that's the plan at present.


Seal the wood with CPES first,, Sika is a good product, mask the joint both sides before caulking with sika, this will keep the Sika from filling the grain next to the joint and give a cleaner appearance. If you varnish over the Sika, this will be your first point of failure down the road. I would probably CPES and varnish before applying the Sika the first time. Future coats you pretty much are stuck applying the varnish over the caulk.
