Polyester UV-Cure Grain Sealer

Rated 4.00 out of 5 based on 9 customer ratings
(9 customer reviews)


Reactive (high-solids) finishes cure by chemical reaction and require less build-up (coats) to fill open grain woods. They have less shrinkage than solvent-borne or water-borne “evaporatives” – those that cure by drying. One problem in applying reactives to oily woods is that the natural oils in the woods interfere with the curing of the reactive finishes. Shellac is often used to seal the grains on oily woods but this takes a fair amount of time. Solarez UV-cure grain filler and sealer reacts not by evaporation but by photochemical reaction and does so in seconds, not hours.

Solarez Grain Sealer was ranked in the top 10 of all wood fillers and epoxies. Check the review out here.

    I’m still getting my moves down with the sealer but my initial impression is that it is a very good product. It is very thin and brushes on and squeegees off easily. It sands easily too which is always a good thing. My testing with this product so far is limited to mahogany and walnut and I’ve had good results so far with multiple coats to fill the deep pores. Because this stuff cures rapidly under UV light you can apply about 5 coats in the time it takes for one coat of paste filler to dry enough to be recoated. That means you can take a mahogany guitar body from raw to high gloss in about 3 hours. Crazy stuff.

    I am not to happy with these products they are not setting as described I am brushing these on my pieces and letting them sit for brush strokes to even out then I move them to direct sun light but the are not curing in set time periods they are taking 20 to 30 mins to cure and even then they are still tacky to the touch according to your sight they are supposed to be fully cured in 3 mins at this point I am very disappointed in these products not to mention they have ruined two of my projects wich now have to be re done

    I used this product on both the hull and deck of a plywood paddle ski I just completed. The deck is so firm after 2 coats I will probably only fiberglass the hull now.

    I would get up early and apply a coat and then wait for the surise as I was working under a carport.

    Pretty awesome stuff!

    I give this 5 stars because it is the fastest, easiest way to grain fill open grained wood for electric guitar bodies. What makes this so good for this purpose is the fact that you can put on a coat…pour in on and level with a credit card…or you can spay it on. (In my use I have found that it does not level very well when sprayed..I think it is too thick to “flow out” when sprayed. It will stiffen very quickly as you move it around with a spreader or credit card so you cannot overwork it…….But the great thing is it cures in under 3 minutes in direct sunlight. You can sand it down after this 3 minutes..It sands easily…Put on another coat..cure and sand until you get all the grains filled. If you have just a few spots still not filled just fill those spots…cure and sand. No problems with witness lines…If you are a guitar maker you will be thrilled with this. You body will be ready for the top coat in an afternoon.

    Well worth the price. product can be replaced into continer it came from (as long as it has not been exposed to UV). This makes for multiple uses. Cost effective.

    I have made several live edge cedar end tables, and have used Solarez Grain Sealer and High Gloss Polyester finish to to seal and finish the end tables. These products worked better than I expected. The dry time of the UV cure is approx 6 mins. I can finish my projects in one day versus several days of using varnishes.
