Directions

Where to Use
Interior Water- Based Sanding Sealer is recommended for use on interior wood surfaces as a sand-able base coat or sealer prior to the application of varnishes and polyurethanes. This product may be applied to all types of bare or stained woods.

Surface Preparation
All surfaces must be clean, dry and free from dirt, wax or grease.

New Wood: Sand the wood thoroughly with medium grit sandpaper and progress to fine grit sandpaper. Always sand in the direction of the wood grain. Sand smooth and remove dust particles with a rag dampened with water.

Previously Finished Surfaces: Completely remove the old finish to bare wood and follow the surface preparation directions above. When applying over stained wood, ensure stain is thoroughly dry. Remove all dust prior to application.

Application
Stir thoroughly before and during application. DO NOT SHAKE. Sanding Sealer appears milky in can but dries clear.

• Sanding Sealer can be applied by brush, roller or sprayed. If necessary, thin with approximately one pint of water per gallon, as needed for            spray application.
• Apply in full, even coats in the direction of the grain. If brushing, apply liberally and keep a wet edge, working quickly to ensure an even coat.
• Large, flat surfaces may be rolled and quickly leveled off with a brush. One coat thoroughly seals and prepares the surface for succeeding coats    of clear finish.
• Allow surface to dry approximately 30 minutes before sanding. When sealer has dried completely, smooth sealer by sanding with fine                    sandpaper. Be careful when sanding not to sand through the sealer film and remove the stain color.
• Remove all sanding dust with a clean rag dampened with water and apply desired finish coat.

Please note: Testing is very important when applying this product over paints or stains because the appearance of these products may change when a water-based finish is applied. This product gives a soft wood amber that ONLY becomes noticeable when applied over white or pastel paints and stains.

Thinning
Thinning is not recommended, but if necessary, a small amount of water may be added. For spray applications, up to one (1) pint of water per gallon may be used.

Coverage
Approximately 200 to 400 square feet per gallon depending on the type and porosity of the wood.

Drying Time
Apply when air and surface temperatures are between 60° and 90°F and humidity is between 30% and 70%. Interior Water-Based Sanding Sealer will dry to touch in 10 to 15 minutes and can be sanded after
30 minutes.

Cleanup
Wash brushes and equipment in warm, soapy water. Rinse clean.

Recommended Finish Coat
We recommend Old Masters® Water-Based Polyurethane and Exterior Water-Based Spar-Urethane. However, Old Masters® Oil-Based clear finishes can be used when sealer is completely dry. If necessary, this sealer can be topcoated with most types of water-based polyurethanes and varnishes.

MAX VOC: 335 grams/liter (2.8 lbs/gal)

Proper Surface Preparation

Proper surface preparation can be the most important step of any stain or finish project. Below are some helpful tips that will help you achieve a professional looking finish every time.

FILLING WOODGRAIN     Some open-pore wood species or woods with large imperfections may require an additional step to prepare the surface for staining and finishing. Creating a smooth finish on these woods can be obtained by using Old Masters® Woodgrain Filler. Use on hardwoods, such as oak, ash and mahogany. Use as directed.

CONDITIONING       Some woods like pine, fir, maple and poplar absorb stain unevenly creating a blotchy appearance. Old Masters® Wood Conditioner is a clear wood sealer which enables uniform stain application under oil or water based stains. Stain must be applied over Wood Conditioner within 2 hours.  Ideal for use on soft woods which are being stained with or adjacent to hardwoods.

SANDING SEALERS     Use a sandable basecoat or sealer prior to the application of varnishes or polyurethanes. Old Masters® Oil-based and Water-Based Sanding Sealers may be applied to all types of bare or stained woods.  Using these products helps to promote a smooth, fine finish.
