INTERIOR FINISHING

If products cannot be finished immediately, cover with clear plastic to protect from dirt, damage 

and moisture. Remove any construction residue before finishing. Sand all wood surfaces lightly 

with 180 grit or finer sandpaper. DO NOT use steel wool. BE CAREFUL NOT TO SCRATCH 

THE GLASS. Remove sanding dust.
Pella products must be finished per the below instructions; failure to follow these instructions 

voids the Limited Warranty.

• On casement and awnings, it is optional to paint, stain or finish the vertical and horizontal 

   sash edges.

• On single-hung and double-hung, do not paint, stain or finish the vertical sash edges, any finish   

   on the vertical sash edges may cause the sash to stick; it is optional to paint, stain or finish the 

   horizontal sash edges.

• On patio doors, it is optional to paint, stain or finish the vertical and horizontal panel edges.

Note: To maintain proper product performance do not paint, finish or remove the weather-

stripping, mohair dust pads, gaskets or vinyl parts. Air and water leakage will result if these 

parts are removed. After finishing, allow venting windows and doors to dry completely before 

closing them.

Pella Corporation is not responsible for interior paint and stain finish imperfections for any 

product that is not factory-applied by Pella Corporation. Use of inappropriate finishes, solvents, 

brickwash, or cleaning chemicals will cause adverse reactions with window and door materials and 

voids the Limited Warranty.

For additional information on finishing see the Pella Owner's Manual or go to

®

 

or EnduraClad Plus baked-on factory finish that needs no painting. Clean this surface with mild 

soap and water. Stubborn stains and deposits may be removed with mineral spirits. DO NOT use 

abrasives. DO NOT scrape or use tools that might damage the surface.

Use of inappropriate finishes, solvents, brickwash or cleaning chemicals will cause adverse 

reactions with window and door materials and voids the Limited Warranty.

IMPORTANT NOTICE

Because all construction must anticipate some water infiltration, it is important that the wall 

system be designed and constructed to properly manage moisture. Pella Corporation is not 

responsible for claims or damages caused by anticipated and unanticipated water infiltration; 

deficiencies in building design, construction and maintenance; failure to install Pella products in 

accordance with Pella’s installation instructions; or the use of Pella products in wall systems which 

do not allow for proper management of moisture within the wall systems. The determination of 

the suitability of all building components, including the use of Pella products, as well as the design 

and installation of flashing and sealing systems are the responsibility of the Buyer or User, the 

architect, contractor, installer, or other construction professional and are not the responsibility 

of Pella.
Pella products should not be used in barrier wall systems which do not allow for proper 

management of moisture within the wall systems, such as barrier Exterior Insulation and Finish 

Systems, (EIFS) (also known as synthetic stucco) or other non-water managed systems. Except 

in the states of California, New Mexico, Arizona, Nevada, Utah, and Colorado, 

Pella makes no 

warranty of any kind on and assumes no responsibility for Pella windows and doors installed 

in barrier wall systems. In the states listed above, the installation of Pella Products in barrier 

wall or similar systems must be in accordance with Pella’s installation instructions.

Product modifications that are not approved by Pella Corporation will void the Limited Warranty.
