Should you gap plywood sheathing if installing stucco/cement plaster

Should you gap plywood sheathing if installing stucco or cement plaster, Expansions and sheer wall spacing.

For many of you folks who feel, wow, stucco is not all that great as it’s prone to cracking. The cement plaster s of new, say the last 200 years have different amounts of lime in them, when the romans built statues, coliseums, as well as the people who built the pyramids and magnificent and great castles around the world thousands of years prior, lime was used exclusively, these structure still stand the test of time today. Lime plastering was used and as such this lime took quite awhile to set or dry, days, weeks and even months, however the structures that were built with lime plaster absorbs water and or moister then allow this moisture harmlessly and naturally leach out thus no molding and the lime allows flexibility, the facts that is did require days and sometime weeks or even months for these lime creations to dry was the downfall around 81825 by a fella in of course England, who found a superior product called Portland cement plaster. Lime was put on the back burner as the new Portland cement plasters had incredible strength and set quickly today, thus welcome to the fast modern world where everything must be completed quickly. the fact lime structure were able to absorb water and flex , thus stopping the effect or greatly diminishing the effects of parging or cracking, became yesterday’s old newspapers. Say for example with some projects I have shown in older videos, the cement walls have cracked as time created movement, water then got into these cracks, this water sometimes froze, which then expanded, which in turns pops pieces of cement off, it better know as parging. We will be doing a video soon where I am using a BMI reinforced cement plaster with much lime already in these bags, thus normal vibrations won’t affect the home with hairline cracking as much anyway. It’s a boring topic, but one I feel compelled to finally explain, all coming up in a video where this Portland based cement product has a lot of lime added for specific reasoning.

For more quality products that I have been using, showing and recommending in our videos they have stood the test of time say for more than 20 years,(most of them anyway) the magazine below caters to these products, plus they have a really cool cover page at least for the January 2016 addition.
Don’t guess with your biggest investment purchace products that last longer than old kirk
