Full Description

Everbuild Everflex AC50 is a strong and flexible acoustic sealant and adhesive. It can be used for filling gaps in areas where sound might escape and is specially formulated for sealing and bonding plasterboard or insulation boards. It can be used for walls, ceilings and dry linings, and is for indoor use only.

It's acoustic-rated to BS EN ISO 140/3 requirements (the measurement of sound insulation in buildings and of building elements) and is also non-flammable. As the name Everflex suggests, the sealant is permanently flexible throughout its working life, allowing for natural movement. The high-strength silicone is solvent-free, making it more pleasant to work with.

Unlike many sealants, the white Everflex AC50 can be painted over. British brand Everbuild has specialised in sealant, adhesive and building chemicals for almost 30 years, so you know you're in safe hands.

Rated 2 out of 5 by from Beware Had to take 2 tubes back because the seal that pushed the adhesive out was distorted, when you get them check the back that the silver pusher is not miss shaped with adhesive visible

Rated 5 out of 5 by from Great Product Great and easy to apply, very strong and flexible Using 2 Acoustic boards and a Techsound membrane inbetween, i do not hear my neighbours anymore when they were very clear before This product is applied around the edges and joins to prevent any hard edges which may cause reverberations, it remains spongy

Rated 5 out of 5 by from Decent acoustic sealant Used this sealant to soundproof all my new stud walls on my house I just renovated. I placed a bead on every stud beam before placing the plasterboard then sealed the entire outside edges 5mm gap. Each 4 inch stud was filled with acoustic rockwall.. Made a big difference.. Takes away the drum effect with sound travel. 1 tube will do about a 4m stud wall.

Rated 1 out of 5 by from Dryliner with 21 years experience In 21 years working as a dryliner this is the worst acoustics sealant, it drips all the time if the gap is more then 5 mm , I don’t recommend it to any one, better off buying a more expensive one at least you don’t have to go back to redoing it and clean up after it .

Rated 5 out of 5 by from Exactly what I expected Arrived in good time. Exactly as expected.. I would buy this again

Rated 5 out of 5 by from Actually works... I recently installed soundproofing to 2 alcoves to suppress noise from inconsiderate neighbours . Having fitted everything (but not sealed around the required 5mm gap) I was disappointed in the performance of the system. Once I used this to seal the gap everything was so much better! It applies easily and can be smoothed over straight away. It dries to a firm finish but retains flexibility. However much you think you need get another on top as you will definitely use it. Much better deal from Toolstation than the company providing the soundproofing. Very happy with this product.
