Site Preparation

Introduction

In cold weather (outdoor temperatures less than 13º C.), controlled heat in the range of 13º C to 21º C must be provided during application of gypsum wallboard.

This heat must be maintained both day and night 24 hours before, during and after entire gypsum wallboard and joint treatment application and until permanent heating system is in operation or the building is occupied.

Ventilation should be provided to eliminate excessive moisture. In glazed buildings, this may be accomplished by keeping windows open approximately 50mm (2") top and bottom (or side-pivoted windows approximately 100 mm (4")) to provide air circulation.

In enclosed areas lacking in natural ventilation, temporary circulators should be used. Under slow drying conditions, additional drying time should be allowed between coats of joint compound. Drafts should be avoided during hot, dry weather to prevent too rapid drying of joint compound.
