Beschreibung
Deck-O-Seal Pour Grade is a two-part, polysulfide-based joint sealant for expansion joints in pool decks and horizontal concrete. It pours and self-levels into the joint, then cures to a firm, flexible rubber that stretches or compresses up to 25% as the slab moves. Available in Gray (4701032), Desert Tan (4701033) and Dura-White (4701031).
Highlights
- Pours and self-levels: Flows into the joint and finds its own level — no tooling required on horizontal joints.
- Moves with the slab: Handles up to 25% joint movement in extension or compression without splitting.
- Pool chemical resistant: Unaffected by chlorine, salt systems and normal pool water chemistry.
- Will not chalk or crack from UV: Stays flexible in direct sun; elevated temperatures will not discolour it.
- Meets ASTM C920: Type M, Grade P, Class 25, NT. Also CRD-C-506 Type I Classes A & B.
- Pre-measured two-part kit: Base and setting agent come in the correct ratio — no mixing math.
Joint Sizes & Coverage
- Minimum joint width: 1/4″. Do not use in joints narrower than this.
- Maximum joint width: 1″. Joints over 1″ wide require REZI-WELD LV primer.
- Sealant depth: Never less than 1/4″ or more than 1/2″. Maintain a 2:1 width-to-depth ratio.
- Coverage per 96 oz kit: 231 ft at 1/4″ x 1/4″ · 106 ft at 1/2″ wide x 1/4″ deep · 58 ft at 1/2″ x 1/2″ · 29 ft at 1″ x 1/2″.
Not Compatible With
- Underwater or below the waterline: Use Deck-O-Seal 125 or Deck-O-Seal Gun Grade instead.
- Asphalt: Cannot be used in asphalt pavement or with asphalt-impregnated joint filler.
- Painted surfaces: Paint is not recommended over any Deck-O-Seal product.
- Aquatic life: Not recommended for use in ponds or tanks holding fish.
Includes
- (1) 96 oz base material can
- (1) Setting agent
- (1) Stirring paddle
- (1) Applicator squeeze bottle
Note: Backer rod and joint filler are not included and are sold separately. Most installations need them to control sealant depth.
Frequently Asked Questions
Can Deck-O-Seal Pour Grade be used underwater or below the waterline?
No. Pour Grade cannot be used underwater. For joints below the waterline, W.R. Meadows specifies Deck-O-Seal 125 or Deck-O-Seal Gun Grade instead.
How much will one 96 oz kit cover?
Between 29 and 231 linear feet, entirely depending on joint size. A typical 1/2″ wide by 1/4″ deep pool deck joint gets about 106 feet from one kit. A 1/2″ x 1/2″ joint gets 58 feet.
Do I need backer rod?
Almost always. Sealant depth must stay between 1/4″ and 1/2″ at a 2:1 width-to-depth ratio, and backer rod is what holds that depth. W.R. Meadows specifies Kool-Rod or Deck-O-Foam for this. Joints deeper than that waste sealant and perform worse.
How long before it cures?
Tack-free in about 4 hours and firm and rubbery within 24 hours at 77°F. Keep it dry for at least 24 hours after application — cooler temperatures extend cure time. Once mixed you have roughly one hour of working time, so mix only what you can place.
Which colour should I choose?
Gray (4701032) suits standard grey concrete and most poured decks. Desert Tan (4701033) suits warm-toned pavers, sandstone coping and coloured concrete. Dura-White (4701031) suits white coping, light travertine and bright decks. All three are the same sealant.
What is the difference between Pour Grade and Gun Grade?
Pour Grade is self-leveling and is meant for horizontal joints like pool deck expansion joints. Gun Grade is non-sag and holds its shape, so it is the one for vertical or sloped joints and for below-waterline work.
