In the process of sealer/undercoat of interior cement rendered walls skimmed with white set.

I am using Pascol Uniseal.

However - I am having trouble determining where I have just rolled and the amount of sealer I have just rolled on - as the walls appear very "blochy" as I go - nothing like using an acrylic. On close inspection it appears that the blochy spots (darker spots) actually have some sealer on them - perhaps just the cement showing through.....and it is very slow going - about 3 times white it takes me to paint an acrylic undercoat.....because I can't readily determine where I have been and with how much....

In any case - anybody got any tips for using the oil based sealer for interior white set walls? :?
