General Information
1. Recommendations made in this selection and specification guide to Childers® Mastics, Coatings, Adhesives and Sealants are general in nature
and scope. Please refer to the individual Product Data Sheet for complete product information and recommendations to assure proper product
selection.
2. Adhesive use should be predicated upon the user testing the suitability of the adhesive for the particular insulation and application desired.
3. Weather barrier coatings, when applied outdoors, should always be applied over sloped horizontal surfaces to prevent ponding water. Industry
experience has demonstrated that all weather barrier coatings may blister when applied over skinned extruded polystyrene board. Also, a white
color should always be used.
