What does activator do in paint?
activator in the base does a few things.
it helps make the paint more durable by crosslinking it, it helps crosslink the base with the clear.
if you sand through the clear on a repair, activated base will have less of a tendency to wrinkle when recoated..
What does hardener do in paint?
Hardener, (Or activator as it is known in the business) drys the paint by chemically cross-linking the paint into the hardener, making a urethane mix that is much more impervious to chemical attack. Paint will never cure fully if it is not activated.
What happens if you don’t put hardener in paint?
Chances are that without the component that creates the chemical reaction that hardens the paint it will never properly dry. The best thing you can do is take it all off and start over. Painting a finished coat over uncured paint will almost always end in disaster.
Can a 2 pack dry without hardener?
What you’re talking about is Epoxy paint, the answer is yes. Given enough time, the paint will harden without the hardener. Heat is the major cause of Epoxy hardening.
What happens if you put too much hardener in clear coat?
Improper or low quality materials may have an adverse effect on the finished dry paint film. Incorrect mixing ratio: If too much activator/hardener is used, or if the correct ratio is not properly mixed, defects may appear in the finished dried paint film.
Should I sand between basecoat and clearcoat?
Wet-sand the base coat before starting the clear coat. Wet sanding makes the surfaces smoother. … If you wet-sand the base coat, wash the vehicle with soap and water after this step, not before. Once the base coat is smooth and clean, start spraying on about three to four layers of clear coat.
Why did my clear coat wrinkle?
A few different factors can cause the finish to wrinkle or crack when applying another coat of paint. The most common – is applying the paint too thickly – which makes the surface of the paint dry too fast and not the underside. When you re-coat, the solvents in the paint shrink and this causes the wrinkling.
Does 2k base coat need hardener?
With the base coat system, the base coat requires no hardener(only thinner) and really just provides your colour, so 3 coats may not be needed.
How do you mix basecoat?
Mix the paint: 1 part paint 1 part 2k / Basecoat Thinner this may vary depending on spray gun setup and air supply. Apply a cover coat of Basecoat Paint, leave for 10-15 minutes, depending on conditions.
How much hardener do you add to paint?
A mixing ratio given as 4:2:1 normally means 4 parts of base product, 2 parts thinner/reducer, and 1 part hardener. However, some paint manufactures add hardener second, and thinner/reducer last.
How long do you let base coat dry before clear coat?
Allow 30 minutes after base coat color has been applied to apply the clear coat. Apply 4-5 wet (but not dripping) coats waiting 10+ minutes in between coats. Each coat should be dry to the touch (not tacky) before moving on to the next. Do not touch the freshly painted panel to test, you can touch the tapeline.
Why is my clear coat not glossy?
The likely cause is that the paint was applied too thin per coat or the nozzle was too far away. A coat thick enough to get a glossy sheen is seen but not too thick that runs develop is the proper technique. Practice on a similar surface is suggested.
What happens if you put too much hardener in paint?
too much hardener makes paint a bit brittle….. however the bigger issue is adhesion. in the old days you could mix paint to preference. however modern paint formulas rely on “flash times” chemical reactions between layers.
Do you rub down base coat before clear coat?
Do not scuff the base coat beforehand. The clear coat goes on a smooth surface, not a rough one. The clear coat is meant to protect your car, but it needs some special care at first. Do not wax it or take it through a power car wash for the first thirty days.
Is hardener and activator the same?
From a general standpoint activators and hardeners do the same thing; initiate cure of 2K products. However, you must use only the activator each product calls for on the tech sheet and not interchange hardeners/activators from different brands or products.
Do you add thinner to clear coat?
Adding a small percentage of reducer will thin out your clearcoat, making it easier to atomize and give it a better flow while its drying out. I do 10% on 4:1 Clears and up to 20% on 2:1 clears.
How much hardener do I mix with paint?
Mixing Ratios You will normally mix 4 parts paint to 1 part hardener 1 part reducer. If you need to mix part of the paint to do door jams then you should follow the same ratio. Factory Acrylics such as Kirker paints will come in a 3 quart gallon and require a full quart of hardener to be added.
How long should clear coat dry before buffing?
24 hoursIf you have recently applied clear coat to a paint job, it’s time to buff it out to a high shine. Clear coat should be allowed to harden for at least 24 hours before attempting to use a buffer.
Does automotive paint need hardener?
Modern automotive paints are activated with hardeners to promote faster drying times. Reducer is added to help the material flow through the spray gun easily. The mixing process is a vitally important aspect of automotive refinishing work.
What is the difference between activator and reducer?
Some paints simply term their activator an “activator reducer”; most likely due to the activator already having the reduction components in the mix. You probably over-reduced the primer by adding more reducer but it’s not a huge deal – you’ll get less material thickness (film build).
