Things to remember when working with Aerosol Finishes....
- Shake Well. When working continue to shake up every so often.
- Check nozzle before spraying on wood. lightly mist a test spray in the air. spray on a white cleaning cloth to check color and uniformity.
- Always use light dust coats - 8-12" from surface. This requires practice and patience.
- Clean nozzle and spray hose after each use-turn upside down and spray until air comes out. Make sure to spray into drop cloth or area that will not be damaged.
- Shelf life of spray products is approximately 12 months from the time of purchase. Change annually to ensure consistent results.
Blushing and water rings can be repaired as long as_______
the damaged area is white in color. Once the area has turned dark, the water has mildewed the wood and the finish and stain will have to be completely stripped.
What are the steps to remove water rings?
- Evaluate damage area to make the water ring is white in color.
- If white, start by cleaning the area thoroughly with wax wash. Wipe off excess and let dry prior to making any repairs.
- Lightly spray with no blush. Use light dust coats until water ring disappears. Repair should take 15-30 min to dry. If white area reappears, repeat current step.
- Once the water ring is gone and repair has dried, evaluate sheen. If sheen needs adjusting, start with 0000 steel wool and oil. Adjust sheen as needed until repair area is no longer visible to the eye.
What are the typical reasons for dark streaks showing up in wood?
- Mineral deposits that were naturally in the wood.
- Water under the finish which resulted in mildew.
What are the steps to removing dark streaks from light colored wood?
- Mix a solution 50% household bleach and 50% water in a spray bottle.
- Spray this solution onto a small test area of the wood to see if it damages the finish.
- If the finish doesn't damage, spray the solution onto the dark areas and let sit. The stain will start to lighten or the dark will start to run down the cabinet.
- Rinse area by spraying with KTU All Purpose Cleaner
- Repeat as necessary.
- Perform repair and continue with the cabinet reconditioning.
What are the steps to adjust the sheen to blend with the surrounding finish?
- When a repair area is too shiny, lightly rub with 0000 steel wool. Use the dry steel wool to work down the sheen.
- (Wool-Lube mixed 50-50 with water can be used also.)
- Once the sheen is leveled, rub out the area along with the surrounding wood using KTU Cream Polish. Repeat until an even sheen is achieved.
What are some potential reasons for the repair area to have a duller sheen than the surrounding area?
- The repair area is not built-up to the surrounding topcoat. From some angles, the repair will look fine but from other angles it looks dull. The area needs additional coats.
- The top coat has a sheen that is not a glossy as the existing finish. Therefore, recoat with a glossier sheen.
- Mohawk offers training on additional methods which include rubbing compounds and waxes found in the Mohawk Finishing catalog.
What are the 2 basic types of slides? And what does Kitchen Tune-up recommend?
- Side mount slides
- center mount slides
- Kitchen Tune-up recommends an epoxy coated side mounted drawer slide system.
What os the one of the most important aspects of installing drawer slides correctly?
The levelness of the installation. Generally, the slides should be installed and the drawer fully inserted before marking the installation points on the back of the cabinet wall. This will often require a helper to ensure accurate work.
What may need to be added to the two mounting brackets installed on the cabinet box when installing drawer slides?
Filler blocks made from scrap pieces of wood, when the back of the cabinet box is too deep for the drawer slide.
What are the 5 properties of a good cabinet finish repair?
- levelness(follows the surface contour)
What is the most important step when repairing badly damaged areas?
Preparation phase. Clean out any grease, grime or dirt so as to prepare the wood to accept stain. Allow extra drying time because the water or solvents will cause blushing of the topcoat if still found in the fibers of wood being repaired.
Tips for successful Aerosol use...
- Shake well for proper mixing of solids and solvents
- Always check temperature. Ingredients of the aerosol of less than 60 degrees can lead to poor atomization and an orange peeled finish.
- Apply several light coats instead of one or two heavy coats
- Always follow directions on the can for proper cleaning of the valve and tip after each use.
- Plugged tips can be soaked in lacquer thinner to clean and make reusable.
- Before spraying over an existing finish, especially catalyzed and urethanes, the surface should be cleaned and lightly scuffed.
How do paint and varnish absorb into the substrate differently?
Because stains contain lower amounts of binder, the binder from a stain resides mainly below the surface while the pigment remans near or at the surface. Stains that employ metallic pigments, such as iron oxides, usually are more opaque...both by nature of the opaqueness of the particles and also because the particles are much larger than organic pigments and therefore do not penetrate as well. Most wood stains for interior uses require further application of varnish or finish for protection and gloss.
How do stains and varnish differ?
Stains are different from varnishes in that the latter has no added color or pigment and is designed to form a surface film. Some products are marketed as a combination of stain and varnish.
What reminders are necessary when discussing painted cabinets?
Painted cabinets are moving a little closer to the ferrari, both in cost and production time. For an up charge or additional fees, some vendors offer a glaze for a higher end look, and/or custom paint matching. Vendors are very particular about getting painted finishes right before they sign off on a product.
What is often the wood of choice for painted cabinets? And why are painted cabinets often more costly?
Maple. its a very high-end look and will take longer to build. A ferrari is handmade and take much longer to build than a factory line car. The same is true for painted cabinets. While the end results are worth the wait, each step in the process takes longer. It is not uncommon to have an entire order held because a few doors are still not quite right.
What are the benefits of the more costly painted doors?
Painted cabinets tend to provide more depth to a solid color door versus an RTF or laminate. Hand rubbed glazing on RTF provides a higher end look too.
