see Bostik Adhesive Trowel product description
manufacturer part# B11125
size: 1/4” wide x 1/4” deep
Bostik trowel size is suggested to maximize coverage of adhesive. Periodically, check coverage of adhesive during installations.
For moisture control:
• 100% coverage is required for solid wood flooring that is less than 1/2” thick or any bamboo wood flooring;
• >95% coverage is required for all other wood flooring.
For bonding only, check coverage to insure there is 80% coverage for engineered and >95% for all solid wood flooring and bamboo. Uneven subflooring may require the use of either a leveling/patching material, or a larger notched trowel for proper coverage of adhesive.
