Do Diamond paintings need to be sealed? What do you do when you finish diamond painting? What do you use to seal diamond pictures? Diamond painting is done by gluing tiny colored gems (called "drill bits") onto a canvas to create a picture following a pattern. The glue between the bits is a dust collector and once the dust falls between the bits, it is almost impossible to remove the dust, ruining the painting effect. Sealing the diamond painting solves this problem.
There are pros and cons to sealing a diamond painting.
Protection — Sealing diamond paintings prevents drills from coming loose and falling off the painting
Maintenance — Dust built up in the grooves between the painting’s drills is prevented by sealing the painting, making it easier to keep the painting clean
Appearance — A coat of sealant over a diamond painting gives the painting a glossy sheen
Stiffening — Once the painting has been sealed, the canvas becomes stiff and can’t be rolled up for storage
Warping — sealing a diamond painting occasionally causes the canvas to stiffen and warp, ruining the shape of the painting
Tarnishing — some sealants discolor over time, develop a yellowish or brownish tinge, and the painting’s vivid colors dull
What to Use to Seal Diamond Paintings
When it comes to using sealants as a finishing touch to diamond painting, there are many options on the market today. Spray sealants are easy to find and can eliminate some of the problems traditionally associated with applying sealants to frames. Aerosol sealant products typically do not yellow over time, but they do not act as a gelatin-like substance, meaning that any open gaps between your diamonds will not be filled. So if you're still wondering how to seal a diamond painting, keep in mind that spray sealer will retain the natural shine of the diamond and will not yellow, but may leave openings between the diamonds.
Your other option when it comes to sealers is to brush. While this method of sealing diamond paintings is more likely to cause wrinkling or yellowing, it does act as both a topcoat and a glue. This means that any gaps left between the diamonds will be filled with a sealant to keep dirt and dust out of their area. We recommend using mod podge, but be sure to brush in a shallow layer to reduce the chance of yellowing. One disadvantage of using mod podge and other brush sealants is that it will reduce the sparkle of the diamond somewhat, but not completely.
HOW TO SEAL YOUR FINISHED DIAMOND PAINT
As a security measure, put pets and children in a separate room while applying sealant.
Paso 1: make sure all diamonds are correctly positioned by applying weight or using a roller.
Use the same technique that you initially used to flatten your canvas when you first got it. The goal is to make sure all the diamonds are completely flat and glued to the canvas adhesive.
Professional advice : place an old t-shirt on the canvas to avoid scratching or breaking the diamonds.
Paso 2: Dip the tip of your brush into the bottle of brush sealer.
You can use almost any type of brush, foam or bristle. Our official recommendation is theMod Podge brush applicator (in the image): It is sized to give you a lot of control over where the sealer is applied.
Paso 3: start applying the sealer to your canvas with broad strokes.
The sealer will turn thick white at first and look a bit like glue., but it will become more transparent as it dries. Apply a thick but full coat, No need to spill drops!
The glue will work its way through each and every diamond and will harden the next day.
