BEST PRACTICES for STUCCO APPLICATIONS GUIDE Revised April 1, 2019
LENEXA – BEST PRACTICES for STUCCO APPLICATIONS GUIDE Revised April 1, 2019 This document is provided through endorsement by the Johnson County Building Officials. General Exterior wall coverings, along with the roofing, flashings, windows and doors, are designed to provide a weather-resistive barrier that separates the interior of the structure from the elements. Low maintenance and attractive appearance are just two reasons why hard coat stucco has become so popular over the years. At the same time, the building industry has become aware of the need to protect the exterior wall sheathing from moisture damage. The walls shall be constructed so that water does not accumulate within the assembly. This means creating a water-resistive plane behind the exterior veneer that allows moisture that does get into the wall to drain down and out without coming in contact with the wood framing. Detailing around windows, doors and other penetrations in the envelope is equally important in protecting the wood frame structure behind the stucco from being damaged by water infiltration. Since the wall sheathing behind the stucco is the lateral load resisting system of the structure, in addition to the supporting surface for the exterior siding, it is important to see that continuous undetected penetrations of the siding by moisture do not create structural damage such as decay and corrosion or environmental damage which may cause health related problems such as the growth of mold and mildew. To this end, the removal of moisture that gets past the exterior envelope before it contacts the wood framing is the primary goal of the weather-resistive barrier and why it is critical that it be installed properly. -

The peat harvesting will be from several farmland sites in Far North. The processing plant will be located on land owned by the local Iwi Te Runanga o Ngai Takoto (Ngai Takoto)at Kaimaumau. RWHL have agreements with the farm owners and Ngai Takoto (at their Sweetwater property) for access to the resource. Ngai Takoto has agreed to provide land for the process plant at Kaimaumau property as part of their strategy to reclaim and derive income from their unproductive Kaimaumau land. The resin and wax project is seen integral to the Iwi’s plan to develop their land and has their full support. The project has significant economic benefits for the region. It will generate $60 million in export earnings when fully implemented and will provide full-time employment to 50 people of which 80%+ will be local hire. -

BEEVER1 1 Landcare Research, Private Bag 92170, Auckland, New Zealand Corresponding author; [email protected] 2 University of Hawaii at Manoa, Hawaii, United States of America Abstract Phytophthora Clade 5 is a very poorly studied group of species of oomycete chromists, consisting of only two known species P. castaneae (≡ P. katsurae, nom. illegit.) and P. heveae with most isolates from East Asia and the Pacific Islands. However, isolates of two important disease-causing chromists in Clade 5, one of kauri (Agathis australis) in New Zealand, the other of coconut (Cocos nucifera) in Hawaii, poorly match the current species descriptions. To verify whether these isolates belong to separate species a detailed morphological study and phylogenetic analysis consisting of eight genetic loci was conducted. On the basis of genetic and morphological differences and host specificity, we present the formal description of two new species in Clade 5, Phytophthora agathidicida sp. nov. and Phytophthora cocois sp. nov. To clarify the typification of the other Clade 5 species, an authentic ex-holotype culture of Phytophthora castaneae is designated and P. heveae is lectotypified and epitypified. Key words: nomenclature, oomycete, phylogeny, species description Introduction Phytophthora species are important oomycete chromists (Oomycetes, Peronosporales, Pythiaceae) plant pathogens causing significant disease (Kroon et al. -

Photo: Prof. Chen Hualin, CC BY-SA 4.0, zh.wikipedia.org Kauris (Agathis sp.) are conifers Conifers, along with the other Gymnosperms (Cycads and Ginkgoes), first appeared about 300 Ma (Million years ago) at the end of the Carboniferous when the world’s coal deposits were being laid down with the remains of the spore-producing trees of that period. The early conifers looked like modern Araucaria. These trees spread throughout the world and displaced their predecessors. The age of the seed plants had arrived. The conifers are a hardy lot. They survived the largest mass extinction the earth has known, 252 Ma, at the end of the Permian Period. But more challenges lay ahead. Sometime in the next 50 Myr (Million years) one of Gymnosperms gave rise to the flowering plants, the Angiosperms. By 100 Ma, in the Cretaceous period, Angiosperms were widespread. And so the battle began - and still continues to this day. The flowering plants have many features that make them more successful in many environments, so their take-over of many habitats was complete by about 65 Ma at the end of the age of the dinosaurs. But in the world’s harsh environments the conifers continue to not just survive, but flourish. -

Components and Types of Varnishes
Components and types of Varnishes Varnish is traditionally a combination of a drying oil, a resin, and a thinner or solvent. However, different types of varnish have different components. After being applied, the film-forming substances in varnishes either harden directly, as soon as the solvent has fully evaporated, or harden after evaporation of the solvent through curing processes, primarily chemical reaction between oils and oxygen from the air (autoxidation) and chemical reactions between components of the varnish. Resin varnishes "dry" by evaporation of the solvent and harden almost immediately upon drying. Acrylic and waterborne varnishes "dry" upon evaporation of the water but will experience an extended curing period. Oil, polyurethane, and epoxy varnishes remain liquid even after evaporation of the solvent but quickly begin to cure, undergoing successive stages from liquid or syrupy, to tacky or sticky, to dry gummy, to "dry to the touch", to hard. Environmental factors such as heat and humidity play a very large role in the drying and curing times of varnishes. In classic varnish the cure rate depends on the type of oil used and, to some extent, on the ratio of oil to resin. The drying and curing time of all varnishes may be sped up by exposure to an energy source such as sunlight, ultraviolet light, or heat. Drying oil There are many different types of drying oils, including linseed oil, tung oil, and walnut oil. These contain high levels of polyunsaturated fatty acids. Drying oils cure through an exothermic reaction between the polyunsaturated portion of the oil and oxygen from the air. -

Course Description This presentation will describe how wood lath and plaster ceilings were designed so that the plaster is suspended from – not adhered to – its wood lath substrate. As such, a wood lath and plaster ceiling functions as an interconnected, suspended system, and also deteriorates systemically. This presentation will focus on chronic deterioration and compare two methods of plaster assessment: (1) the traditional method of sounding; and (2) an advanced method, which numerically quantifies the structural integrity of an entire plaster ceiling system. Various traditional plaster treatment methods will then be compared to the advanced method of treatment called “Plaster Consolidation”, which also addressed the entire ceiling system.
