Environmental Conditions Varying weather conditions can impact both the quality and appearance of taped drywall joints. Relative humidity, plus temperature, will affect the working characteristics of all joint compounds. For bonding of adhesive, joint treatment, texturing and decorative finishes, temperatures within the building should be maintained at minimum 50˚F (10˚C), both day and night, during joint finishing and drying. Adequate ventilation should be provided to eliminate excess moisture.
ProForm BRAND Quick Set Setting Compounds ® TM ProForm® BRAND Quick SetTM Setting Compounds are quick setting (hardening) type compounds that are not affected by humidity once they have set and dried. They were developed to reduce joint deformities such as ridging and beading and provide shortened joint finishing time. ProFormQuick Set Compounds are suitable for filling voids left in above-grade interior concrete. Required for finishing joints on exterior soffit board.
ProForm® BRAND Quick Set TM Setting Compounds Mixing Mix no more compound than can be applied in the designated set time. Place the amount of water recommended on the compound packaging in a clean 5-gallon pail. A plastic container is recommended because of its ease in cleaning between batches. Add the compound gradually to room temperature clean, drinkable water. Mix the compound until it is smooth and free of lumps. Allow to stand (soak) for one minute, then remix until consistency is smooth and uniform.
ProForm BRAND Joint Tapes ® ProForm BRAND Joint Tape is designed for use with ready mixed or setting type compounds to conceal and reinforce joints of interior walls and ceilings. ProForm® Paper Joint Tape Description Packaging Conceals and reinforces wallboard joints. Tape is 2-1/6" wide and is buffed on both sides to ensure the best working qualities and bond. Center crease allows easy folding for use in corners. Can be used with all ProForm Ready Mix and Quick Set Setting Compounds.

Five Levels of Finish 14 Joint Photographing: The shadowing of the finished joint areas through the surface decoration (telegraphing). Drywall Primer: A paint material specifically formulated to fill the pores and equalize the suction difference between gypsum board surface paper and the compound used on finished joints, angles, fastener heads, and accessories and over skim coatings.
are specified or where severe lighting conditions occur. This highest quality finish is the most effective method to provide a uniform surface and minimize the possibility of joint photographing and of fasteners showing through the final decoration. COMMENTS Critical (Severe) Lighting Areas Level 3 All joints and interior angles shall have tape embedded in joint compound and one additional coat of joint compound applied over all joints and interior angles.
Problems and Solutions Conditions Probable Cause Preventive Action Corrective Action Tape Photographing Slow drying of finishing coats. Too much compound under tape. Joint compound too thin. Correct drying conditions. Embed tape properly. Use joint compound thicker. Use ProForm BRAND Joint Tape. Sand down the tape outline and seal. Refloat if necessary before decoration. Prevent finish coat moisture from re-wetting the tape by applying a thinner coat for fast drying.
Conditions Probable Cause Preventive Action Corrective Action Joint Blisters Too little joint compound under tape. Joint compound too dry before embedding tape. Improper bedding of the tape into the joint compound. Loss of bond (see bond failure). End ply separation. Ruptured wallboard ends or edges. Joints too wide and unfilled. Follow joint compound mixing and application instructions. Embed tape properly into ample joint compound.
Conditions Probable Cause Preventive Action Corrective Action Bond Failure Improper heating and drying conditions. Old stock. Excessive thinning of compounds. Too little compound under tape. Unbuffed joint tape. Oily surfaces. Mixing with dirty or excessively cold water. Compound too dry before embedding tape. Proper drying conditions. Mix in clean container with clean tap water. Rotate stocks. Avoid over-thinning of compound and removing too much compound from under tape.
Conditions Probable Cause Preventive Action Corrective Action Mix too thick for proper spray viscosity and/or improper application such as spraying too slow, overloading surface with spray material and using incorrect spray pressures. Use recommended water volume for mixing to ensure sprayable viscosity. Use proper spray application to ensure uniform dispersion of aggregate and proper coverage. Carefully add water to mix. Use proper spray techniques. Adjust spray pressure.
Conditions Probable Cause Preventive Action Corrective Action Shrinkage Compound used too thin or watery. Applied too soon after mixing. Improper drying between coats. Painting before joints are thoroughly dry. Too deep fills in one coat. Slow drying. Use compound at heaviest workable consistency. Allow to stand before using. Allow thorough drying of compound between coats and prior to painting. Apply additional coats on deep fills. Provide proper drying. Allow to thoroughly dry and re-coat.
