Konstrukt™ Durafill™ K-101 Gypsum Putty and K-103 Fast-Setting Gypsum Compound

Konstrukt™ Durafill™ K-103 Fast-Setting Gypsum Compound is a powder-type gypsum-based filler formulated to patch holes and overjoints that are at least 3mm wide in drywalls. It is highly recommended for high-build and fast curing applications prior to the finishing application of Konstrukt™ Durafill™ K-101 Gypsum Putty.
Konstrukt™ Durafill™ K-101 Gypsum Putty is a high quality water-based and asbestos-free putty developed to patch holes and overjoints on gypsum boards. It contains sufficient binders to secure the reinforcing tape and it gradually increases in strength and hardness as it dries. It has excellent crack resistance and sandability, superior paint compatibility, and minimal shrinkage.
K-101 and K-103 are formulated for interior applications only. These products are specially formulated for use on gypsum boards. Do not use products on concrete substrates.
