Just moved horsies to a new stable. It's single skin 4 inch blockwork, not
rendered, and in the driving rain a lot of damp is coming through on the
courses and some of the blocks. Relative merits of silicone and masonry paint?
I have a compressor so could spray given that it's about 80 square metres.

We've used textured masonry paint for this exact same application (well,
the hay shed - the stables will get done later in the year), and it does
a pretty good job.

textured masonry paint

Thanks, that was my first thought too; but someone on uk.rec.equestrian
recommends Thompsons Water Seal, which I have never used before. Decisions

theyre 2 different things. A clear waterproofer looks way better than
paint in most cases. And it doesnt need regular repainting.

The cause of the problem may be poor mortar, if so repointing is the
best solution. 4" walls are very weak when the mortar is unsound.

There can sometimes be problems with applying waterproofers,
particularly to walls with no DPC. It leaves them far less ability to
dry out, thus mould can occur. If this happens, injecting a DPC is
oten effective, and using only breathable paint etc on the interior
may work too.

It's *definitely* penetrating damp from driven rain on the outside (fairly
exposed spot). I was only planning to treat the outside, when it's dry, so
drying out should not be an issue.
