Sanding sealer dries to the touch in 10-20 minutes. Example of use: • Apply 1 coat of Sanding Sealer: finish sand before applying topcoat. Apply 1 coat of Sanding Sealer; finish sand before applying paint.
Just 1 hour after application, it sands quickly and easily to a fine powder, delivering great results with minimal time and effort. This sanding sealer builds even faster than two coats of varnish and is more forgiving of application inconsistencies - even if it drips or sags, it quickly sands out.
Sand Down the Sealer: Once the sanding sealer has dried for at least an hour, sand it with a fine-grit (240 grit and up). Use the shop vacuum to remove the sanding sealer dust, followed by clean rags to clean up any remaining dirt. After cleaning off the dust, you can paint or clearcoat the surface.
Application. We recommend no more than 1-2 coats, then finish with 1-2 coats of topcoat. Sanding sealer can be used with all of our water-based and oil-based finishes EXCEPT Endur-o-var.
Sanding sealer gives an added layer of protection to the wood and creates a nice smooth finish. It can be used on stained or unstained wood. Staining or leaving the wood natural is your first step in finishing. The second step of the 3-step process is a sanding sealer to create a stronger, longer-lasting finish.
The thin viscosity makes it easy to spread and allows it to penetrate into porous woods. To start apply 1 thin coat and allow it to dry. Lightly scuff sand to remove any raised grain fibers, then apply an additional 1 to 2 coats to seal wood and provide an excellent surface that will be ready to topcoat.
Ingestion May cause nausea, headache, dizziness and intoxication. Skin contact This product is rapidly absorbed through the skin and may cause symptoms similar to those of ingestion. Repeated exposure may cause skin dryness or cracking. Eye contact Causes serious eye damage.
On bare wood, the first coat will dry to the touch in 5-10 minutes and can be sanded or recoated in 20-30 minutes. Subsequent coats or coats applied over existing finishes will dry to the touch in 10-15 minutes and can be sanded or recoated in 1 hour.
Finish sand between coats with a fine-grade (220-320) foam sanding pad or 400-grit sandpaper to improve smoothness and adhesion.
Regular readers will know that we do not recommend over-thinning the Cellulose Sanding Sealer; it's a common myth that it needs to be thinned 50/50 to work better, but as a general rule this is incorrect.
It's a good idea to do this fine sanding between coats anyway to remove dust nibs. But polyurethane doesn't bond so well over finishes marketed as sealers, especially over sanding sealer. This sealer is good for use under non-polyurethane varnishes because regular alkyd varnishes gum up sandpaper.
Expert Tips For an Extra Smooth Finish:
A sanding sealer is not the same as a wood conditioner. Whereas a wood conditioner is a pre-stain treatment that reduces blotchiness when staining, a sanding sealer is applied only to bare wood that is not going to be stained.
Allow the second coat to dry 1 hour before sanding lightly and applying a finish coat. Brush Application – For best results, use a natural bristle brush. Apply the sealer to the surface using long and even strokes, brushing back into the wet material to maintain a wet edge.
Thinning: Mix Sanding Sealer SS-501 with Lacquer Thinner at a rate of 1:1 (equal parts). Brush: Use a good quality nylon or polyester brush.
It's the perfect sealer for acrylic finishes because it brings out the natural beauty of wood but will not turn yellow with age.
Unlike cleaning and polishing, sealing requires not using the surface at all for 2 hours and waiting 24 hours before polishing to allow the sealer time to cure.
Wood dust becomes a potential health problem when wood particles from processes such as sanding and cutting become airborne. Breathing these particles may cause allergic respiratory symptoms, mucosal and non-allergic respiratory symptoms, and cancer.
Apply one single coat with a brush or cloth and wait for it to dry. Not very long, an hour or so in warm conditions. Apply a coat of wax, or you can give it a second application of sanding sealer and then wax it.
(In fact, sanding sealer will hinder the bond of polyurethane, so you shouldn't use it.) Think of sanding sealer as a production tool. If you're finishing large objects such as a set of kitchen cabinets, it will speed your work. Sanding smooth will be easier before applying the topcoats of varnish or lacquer.
You can achieve an excellent finish with polyurethane without toner or basecoat, which gives it more edge than sanding sealer.
The main difference between an undercoat, sealer, and primer is that primers are applied to a new surface, while sealers are used as either the substitute to a primer or they are applied before the primer. An undercoat is typically used on a surface that has already been painted.
