Sorting Arrays. PHP has several functions that deal with sorting arrays, and this document exists to help sort it all out. The main differences are: Some sort based on the array keys, whereas others by the values: $array['key'] = 'value';
Can I install Roof-TopÂ® EPDM membrane directly over an existing roof? You can install Roof-TopÂ® EPDM membrane over an existing roof only if a new layer of 5/8â plywood, 5/8â OSB board, or polyisocyanurate board with a fiberglass backing is used as a barrier to protect the EPDM.
Liquid Rubber EPDM will be somewhat tacky for 12 hours. It will still not be fully cured, but you will be able to walk on the roof/surface within three days. Assuming temperatures are above 70Â° a full cure can be expected in 5 to 10 days.
