Abstract
We executed research for compatibility of the building coating materials and the sealants for construction,in the last couple of outdoor exposure test.These outdoor exposure tests were the collaborative research with Japan Building Coating Materials Association,Japan Sealant Industry Association and Building Research Institute.We started outdoor exposure test again from 2005 October with the recent building coating materials and the sealants for constraction,because 10 years had passed from previous collaborative research.In this study,reports concerning the result ot 1 year later.The surface soil of the building coating materials had an influence on the type of the sealants for construction.Several types which consider soiling prevention (non-bleeding type of polyuretane sealant and the like),it was verified that it is difficult to get dirty.In addition,the soiling prevention effect by the barrier primer was remarkable.And the surface crack of the building coating materials,it had an influence on the type of the building coating materials.
