When levelling a Burn-In stick with a hot knife, marks are left in the finish, what is the cause and remedy?

A: The finish is being damaged by the hot knife melting it. Always keep the hot knife moving as close to the same plane as the repair. B: Apply plenty of Burn-In Balm around the repair area to prevent damage.


After levelling a Burn-In stick small holes appear, what is the cause?

A: You are seeing air pockets that were trapped in the burn in stick. To eliminate this add the stick slower and if possible with less heat. B: Bubbles may be from air being trapped in the repair/fill. "Dab" knife into repair to aid in air removal, refill slowly and re-level after.


Why, when sanding down a Burn-In stick to level, the finish around the repair is removed, leaving a halo?

Could be caused by not using a block with clean "wet and dry" paper, or in some cases the finish is so thin that before any sanding is done a couple of clear finish coats should be applied to give something to sand on.


How do I get rid of the shiny spot after I've done a Burn-In?

A: Padding the area with a padding agent prior to spraying with an aerosol will act as protector and not allow the solvents from the aerosol to be absorbed into the Burn-In. 
B: Use Burn-In Sealer over repair area being careful not to spray too heavy because this will show through on final topcoat.


When spot spraying repairs with clear aerosols, it leaves a "haloing" effect.

You can start by making sure the aerosol is the correct compatible product for your use. Our Pre-Cat Lacquer aerosol does an outstanding job of blending in on most nitro and synthetic finishes. However, if need be, take Wool Lube with 4/0 steel wool; rub gently with the grain, end to end. This should correct the "halo" by evening the sheen.


What can I use to mix the Furniture Powders with?

There are several different types of vehicles for the Furniture Powders; Most commonly it can be applied by a cloth or a wetted brush with Qualasole or Wipe On Water Base Urethane. It can also be padded on with French Lac or brushed on with 2 Minute Repair Liquid.


When doing Burn-Ins, I always have "little marks" left in the finish. What causes this?

This is generally caused by the burn in knife coming in contact with the surface too hard. Instead of "dropping and dragging" your knife, try to let the knife come in contact with the surface while dragging. This is something that needs to be practiced, so don't be discouraged if it doesn't happen right away. Try to use an action like an aircraft performing a ‘touch and go’.


How do you properly mix the Epoxy Putty Stick?

You knead it like bread. It should be 1 colour when mixed correctly and should not have any marble like streaks.


How hard does the Epoxy Putty Stick get?

It gets hard enough to saw, shape, sand or carve. It is very similar to the hardness of a hardwood.


On open grain woods repair doesn't look natural.

Repair is "solid." A: Cut pores or grain into repair. B: Use graining pen or pencil to create grain and/or pores.


Fill Stick is hard/brittle.

Stick is very old or stick is very cold. A cure may be simply warming the stick, or replacing it.


Fill Stick colour specks in the repair areas.

Some of the pigment colours are not finely dispersed. Usually only found in sticks at the end of a batch. No cure for it except to notify Behlen.


Burn-In Stick supplied is broken.

This is normal. Broken sticks perform the same. If excessively broken notify Behlen.


Burn-In Stick repair pops out of damaged area from any type of impact.

Damaged area could be too smooth where stick is melted in or the damaged area may be contaminated with wax. Clean the damaged area but leave it somewhat rough to give repair material tooth.


Burn-In Stick repair area "glosses up" when finish is applied.

Burn-In material is glossy and needs a barrier over it to control sheen. Apply Burn-In Sealer over the repair. Use 2-3 light coats (mist coats).


EPOXY PUTTY remains tacky after curing.

This tackiness on the outside of Epoxy repairs is part of the chemical nature of the product. It is easily eliminated by lightly sanding it.


EPOXY PUTTY will not harden.

The 2 parts were not measured accurately. Or: The 2 parts were not mixed sufficiently. Or: 2 like parts were mixed (both parts are hardener or both are resin). Be sure to measure reasonably accurately and mix thoroughly (at least one minute of blending before using.)


Need to tint the EPOXY PUTTY.

Epoxy Putty can be tinted with small amounts of Furniture Powders by thoroughly mixing it into the resin part. Adding large amounts of Furniture Powder weakens the epoxy repair.


Qualarenu Amalgamator does not soften the finish at all.

Qualarenu Amalgamator works on conventional lacquer and shellac finishes. Catalysed lacquer, polyurethane , conversion varnishes and other Hi Tech finishes cannot be amalgamated.
