Acrylic Sealant for uPVC Doors and Windows
Acrylic sealant is a popular choice for sealing uPVC and aluminium doors and windows. Often, manufacturers ask which sealant to use. The usual answer is the cheapest option.
However, buyers rarely check sealant quantity per bottle. As a result, the lowest bottle price may not mean the lowest sealing cost.
True Cost of Sealing
If cost matters, should we compare bottle prices alone? Or should we calculate total sealing cost per door or window?
This cost includes:
Sealant quantity per door
Application labour
Repair costs during warranty
Reputation loss from leakage
Cost per ml or gram
Therefore, choosing the right acrylic paintable sealant is essential.
Making the Right Choice
Several acrylic sealants work as uPVC gap fillers. Hence, selecting a quality product reduces repairs and lowers long-term costs.
There are few popular options to be used as uPVC window/door gap filler sealant.
Advantages | Disadvantages | |
Silicone Sealant | Flexibility Weather Resistance | Inadequate adhesion with surface Difficulty in finishing, aesthetics Higher cost |
Acrylic Sealant | good adhesion Finishing easy, aesthetics Paintable Low cost | Low flexibility not high gap fill ability |
Putty | Low cost Paintable | Cracks with time Rigid High application cost |
Window Sealant – Key Properties
A good window sealant stays flexible. It stretches during expansion and contraction. Therefore, high elongation matters. Moreover, it resists UV and weather. Strong bonding ensures long life. In addition, it must be paintable and cost-effective. It should fill gaps up to 6 mm. Finally, anti-mould protection is essential.
Best Acrylic Sealant for Windows
This acrylic sealant suits uPVC doors and windows. It bonds to uPVC, concrete, brick, and granite. Furthermore, it fills gaps well and gives a smooth paintable finish. It also resists UV and harsh weather. Plus, its water-based formula stays solvent-free. Most importantly, it costs less than silicone.
Application Method
First, clean the surface. Next, apply a uniform bead. Finally, smooth with a wet sponge or finger.

Acrylic vs Silicone Sealant: Key Differences
Acrylic and silicone sealants look similar. Both fill gaps effectively. However, choose based on your needs.
1. What They Are Acrylic sealant dries matte. Silicone sealant cures glossy. Both feel rubbery when cured. Acrylic uses water-based formula. Silicone relies on silicone polymers.
2. Main Applications Silicone stays permanently elastic. Use it where joints move a lot. It excels in bathrooms and kitchens. Anti-fungal types prevent mold. Apply it for expansion joints, sanitary areas, floors, and walls.
Acrylic offers plastoelastic properties. Paint over it easily. Use it on porous surfaces like plaster, walls, wood, masonry, concrete, plasterboard, and window sills. It suits interior strain joints and connections. Avoid constant water contact.
3. Advantages & Disadvantages Acrylic advantages: Paintable, low odor, good on porous materials. Disadvantages: Not for damp areas (risks mold), attracts dust, shrinks during curing.
Silicone advantages: Fully elastic, waterproof, great movement tolerance. Disadvantages: Not paintable (except specials), strong odor in cheap grades, shrinks in low-cost versions.
4. Application & Curing Both load into caulking guns (manual, battery, or pneumatic). They come in cartridges or sausages.
Acrylic cures fast in warm, dry air. Water evaporates outward. Thicker joints take longer. Use on absorbent, porous substrates. Primer usually not needed. Not for waterproofing.
Repair old acrylic joints with the same material. Clean first. New bonds stick well to secure old ones.
Pick acrylic for paintable interior jobs. Choose silicone for wet, moving areas. This ensures durable seals every time.
