Has anyone ever used the “Surfboard Sealer and Polish” from Fiberglass Supply? I thought it was a spray, but it seems that you apply it with a cloth rag. Here is the description from their website:
Surfboard Sealer & Polish, a tough durable acrylic sealer for a quick and easy way to seal “sanded finish” surfboards. Provides a shinny invisible ultra violet resistant coating for protection against salt water damage and scuffing. Saves weight by eliminating the requirement of a Gloss Resin for sealing. Use on “sanded finish” sailboards also.
I’m curious to hear any feedback, because I just purchased a quart of it. I’m thinking of sanding the hotcoat to 320 or 400 and then applying some of this stuff. Do you think I need to sand again after applying like on a gloss coat. Let me know what you think.
The board was sanded down to 220. Then I brushed on the sealer. Ended up not liking it. Brush strokes over the enitre board. Lost the smooth feel of a 220 sanding. I suppose sanding the sealer would help but it would probably all sand off. It has very lil thickness to it.
Howzit rick, I have used acrylic sealer for years. The trick to applying it is to either sray it on or use a sponge ( my way ). put 3 coats on the board making sure each coat is completely dry before applying the next coat. After the board has 3 coats on it use a green rice pot scrubber attached to a 6" ferro pad to knock down the shine of the sealer. This is the better finish since it is slocker than before sealer is scruffed. One way to see the difference is to try and slide a towel on the finish before you scruff it and after. the towel won’t slide very much before, but after scruffing it will slide right off the board which in turn makes for a really good finish.

Hi Kokua. When you say you apply with a sponge, do you mean you use a foam brush? What size would you reccommend? Also, is the attached picture the type of rice pad scrubber that you use? Thanks for your help…I’m anxious to try it out.
Howzit FishGuts, I buy those big Cello sponges That are about 6" long and about 2" thick and cut them in half to apply the sealer. Start at one end of the board and use 1 continious stroke to the other end. I usually start down the center of the board and work my way towards the rails on both sides of the stringer. I guess you could use a foam brush. One thing is after using the sponge I rinse it out with water and put it in a ziplock bag to keep it from drying out. The pads in your picture are the right ones, you can get ones that are big enough to cover a 6" ferro pad and attach the scrubber to the pad with tacky or super 77 and use that pad only for this application. Just knock down the shine of the sealer, you don’t want to scrub the sealer off. Hope this helps. Aloha,Kokua
Howzit reverb, I never do posca pins on a sanded board that isn’t getting a gloss. The acrylic sealer I normally use is also a acrylic thinner so it might just erase the pin line. I always spray the pin lines on the foam if it’s a sanded finish. But I can see that spraying the seaker over pins would be OK since you aren’t running a sponge over them. I just found that it was easier to use the sponge so I didn’t have to clean the spray rig. Yeah the sealer I use is water based and if I don’t clean the sponge the acrylic will build up and leave the sponge yuchy after a while.
ozzie I think 220 might take the acrylic off but I might try 600 grit to knock the acrylic down, but the scrubbers work fine for me and they are cheap.Aloha,Kokua
I meant dust it lightly with the palm of your hand to knock the shine off. Even under a piece of foam. 320 does ok also. But if you put it on a machine, it definitely would take it off. The finer grits clogged up to quick for me. But that’s just in a pinch if you don’t have anything else.
