After further research by our technical department, we have not evaluated the SealGreen Fishing Sand over the Deck -O-Seal joint filler. You may want to try a quart of our product no guarantees. Depending on how dense the Deck-O-Seal is it may hold the finishing sand on the surface. Our SealGreen 45 SSL and 116 Caulk for joint sealers are denser and will hold the SealGreen Finishing Sand
